DESMOPOL DW. Polyurethane membrane designed and approved for contact with water destined for human consumption

Desmopol DW. The polyurethane approved for contact with water destined for human consumption  The DESMOPOL range of polyurethane membranes continues to grow; just recently we introduced the new DESMOPOL CB, a modified polyurethane elastomer with one component bitumen, now it’s the turn of the new DESMOPOL DW (named after the initials of “drinking water”), specifically designed for use in situations where the membrane will inevitably come into contact with water designed for human consumption. The Tecnopol R+D team has been working hard on the development of this membrane for more than a year, and after numerous tests, they have successfully perfected the formula which now meets all our exacting internal quality standards and with which we are fully satisfied.     The quality tests are designed to determine the suitability of the product in terms of the following mechanical properties: elongation, adherence, viscosity, tensile strength, etc.  After completion of the first phase of testing, we then proceeded to the second stage to determine whether the product complies with the requirements of the purpose for which it is ultimately intended, namely, in this case, contact with drinking water.  After several months of rigorous testing it was confirmed that there was no transfer of membrane particles to the water, after which the product was sent to the NSF laboratories in the UK to undergo the official test procedures for formal approval and certification of use.   DESMOPOL DW has now successfully passed all the tests conducted at the UK based NSF laboratories, and has been duly granted the certificate for use on surfaces designed for contact with water destined for human consumption.   Results were excellent on all the test certificate procedures, which included the following:    Smell and taste of the water (unchanged) Appearance of the water (unchanged) Growth of aquatic microorganisms (no signs detected) Release of potentially harmful or toxic substances (no signs detected) Release of metal traces (no signs detected) DESMOPOL DW passed all the tests conducted by the NSF laboratories and is now officially classified as safe and suitable for use in contact with water destined for human consumption. 


We have expanded our PRIMER range with a variety of new resins.

We will go on to explain their properties and how to select the one best suited for each type of use.   Buying a suit off the peg in a large store is not the same as one made to measure  from a tailor. We could go out dressed in either, but if we expect it to fit perfectly, just like a glove, we would have to opt for the second.   The same is largely true with primers; if we want the job to be finished perfectly and avoid problems in the future we need to select the right product, designed for the type of surface, the prevailing climatic conditions and the system employed. In other words we need to select a primer that has been “tailor made” for our specific needs.  We have developed a range of resins with different properties to maximize adherence to all types of surface, porous or non-porous, and in different temperature and humidity conditions, designed to facilitate the application of all our membranes and flooring systems.     Which primer do I need? PRIMER PU-1000 Resin suitable for repairs and overlaps   PRIMER EP-1040 Maximum adherence on systems used on metal   PRIMER PU-1050 The best option for concrete  PRIMER EPw-1070 All types of surfaces in medium-damp conditions   PRIMER PUc-1050 For concrete in cold environments  PRIMER WET Porous surfaces subject to maximum damp PRIMER EP-1020 Resin ideal for epoxy systems on concrete PRIMER T For use in totally transparent systems   Chief properties of the primer range

Pin-holes, what they are and how to prevent them.

PINHOLES are small craters which form in the applied product during the drying process and which, apart from an aesthetic problem, can also cause functional difficulties, especially in waterproof membranes as they can adversely affect the resistance and efficiency of the coating.       Pin-holes through air or solvent trapped inside the membrane  When membranes are applied which contain solvents it is important to apply thin coats to prevent the appearance of pin-holes. The reason for this is that solvents are very volatile and tend to rise once the membrane has been applied. With a thin coat this is not a problem; the solvents will evaporate more, but if the coat is very thick, apart from a greater concentration of solvents, they will not have time to escape and will remain trapped inside the membrane forming bubbles in the surface. In some cases these bubbles may actually break through the surface, causing the appearance of pin-holes.   In the case of DESMOPOL polyurethane membrane, we can completely eliminate the risk of the appearance of pin-holes or bubbling with the addition of DESMOPLUS. This additive allows the application of DESMOPOL in a single coat with the desired thickness, producing a completely smooth finish with no bubbling or pin-holes. This same problem can occur if the product is foam based or contains air. This is usually due to over energetic stirring of the product. To prevent this we simply need to take the precaution of stirring the product on a slow speed and, if possible, with a basket shaped head.        Pin-holes through trapped air below the membrane  If one applies a polyurea or polyurethane membrane, using spraying equipment, directly onto an untreated or inadequately prepared surface, one is bound to end up with air trapped under the membrane.  This air is less dense than the product which contains it, and while the latter is drying, the trapped air rises to the surface and may cause the feared pin-hole effect.  This same phenomenon occurs when a primer is not applied or the coat is too thin or insufficient.  With the application of hot membranes the drying process is much shorter, which might lead us to believe that the air would not have time to escape, however the membrane temperature in fact also warms the air, making it rise faster, also causing the pin-hole effect.     THE 4 BASIC TIPS FOR PREVENTING PIN-HOLES Always stir the product at low speed and with a “basket” type head  Always correctly prepare the surface to leave it as smooth as possible. Ensure there are no cracks, cavities and other irregularities.  Correctly prime the entire surface, using one or more coats, to ensure that it is as flat and smooth as possible.  When not using the DESMOPLUS additive, which allows application in a single coat, always apply several thin coats.     



DESMOPOL obtains the anti-roots certificate. Membrane with guarantees for the construction of green roofs, an ever more common feature in architectural projects in city centres.   In 2014, together with the Eduardo Torroja Construction Science Institute, we began tests to determine resistance to root penetration, in accordance with the EN-13948 standard, for the DESMOPOL polyurethane membrane (system listed under ETE/ETA 10/0121).     DESMOPOL DW obtains the certificate for contact with drinking water.  The new DESMOPOL DW has successfully passed all the tests conducted by  the UK based NSF laboratories, officially certifying that DESMOPOL DW is suitable for use on surfaces in contact with water destined for human consumption.

What is Polyurea

Polyurea description The polyurea is a synthetic polymer obtained from the reaction of a diamine with a diisocyanate, polymerization reaction is very similar to polyurethane one, but in case of polyurea, resulting link is a "urea", so it is called polyurea. By this link we get from generating molecular structure an insensitivity to moisture, thus making the polyurea (if pure) the best waterproof membrane. We say "if pure" because in the market there are numerous polyurea-called "hybrid", which are a mixture between polyurea and polyurethane. These membranes do not have the same mechanical properties as the pure polyurea (elongation, abrasion resistance, etc ...). The following graph clearly shows the difference. Polyurea (pure) = Polyamine + Isocyanate Polyurethane = Polyol + Isocyanate + Catalyst Polyurea (hybrid) = Polyamine + + Polyol+ Isocyanate   Polyurea types (pure) Depending on polyurea chemical structure, it could be of two types: aliphatic or aromatic. The aromatic polyurea is more tenacious and not resists UV exposure, causing some discoloration and loss of shine, which is not recommended for applications "face side". On the contrary, aliphatic polyurea is resistant to UV radiation and it is excellent as a finish coat, because of its raw materials high costs, it makes it  a polyurea of higher price range.   Polyurea application The application of the polyurea is normally performed in hot state; for that is needed a hot spraying plural components (2-components) equipment under high pressure (type GRACO Reactor E-XP2). This equipment is capable of providing a pressure of 2700 psi at a temperature of 70 ° C.  This kind of polyurea dry only in 3 or 4 seconds once applied. There is also the called cold polyurea or polyurea cold applied, it not requires a spraying equipment because it is processed manually using a rubber float, spatula or trowel. This polyurea takes longer to dry than faster one hot sprayed. Advantages and Properties of Polyurea There are many advantages and properties of polyurea membrane, then the most important detail: membrane without joints or overlaps and of maximum flexibility - up to 600% elongation. Polyurea uses Polyurea properties make it a product for applications where waterproofing, protection and durability are fundamental. The endless possibilities for polyurea coloration are a clear advantage in those applications where the aesthetic aspect plays an important role. The adaptability and adhesion of the polyurea allow use in almost any application requirement waterproofing, coating and / or protection can include: waterproofing and corrosion protection on steel, concrete and many other supports.   Polyurea varieties In Tecnopol, we are constantly innovating in the creation and development of new products and the improvement of existing formulations. Currently, we have different membranes according to your needs:  


A practical guide to ensure that you always choose the right primer

TECNOPOL PRIMER, DISCOVER MORE ABOUT OUR RANGE OF PRIMERS We are sure that it would no surprise you to hear us say that every project is different. The characteristics of each project are determined by the type of substrate to be treated, as well as its state, prevailing climate conditions (temperature and humidity) and the system to be used. Based on our experience we can affirm that one of the most important steps to guarantee the system’s success is the primer, both in terms of choosing the right product and as regards its application. Carrying out this step correctly guarantees the success of the job and avoids the setbacks and problems that could arise in the future. At the moment we have a range of 5 different kinds of primers that cover the wide range of substrates and conditions that you may have to deal with in your projects. PRIMER EP-1020. 100% solids epoxy based primer PRIMER EPw-1070. Water based epoxy primer PRIMER PU-1000. Polyurethane primer solvent based PRIMER PU-1050. Polyurethane primer 100% solids PRIMER PUc-1050. Polyurethane primer 100% solids for low temperatures  The following comparative table shows the main characteristics of our primers:   PRIMER EP-1020 PRIMER EPw-1070 PRIMER PU-1000 Type 100% SOLIDS EPOXY WATER-BASED EPOXY SOLVENT-BASED POLYURETHANE Density 1.050 kg/m3 1.000 kg/m3 1.110 kg/m3 Adherence to concrete > 2 MPa > 2 MPa > 2 MPa Maximum substrate humidity 4% 8% 5% Pot life 50 min (23ºC) 60 - 90 min (23ºC) -- Time to touch dry +/- 5 hours (23ºC) +/- 5 hours (23ºC) +/- 1 hours (23ºC) Re-application time 24 hours  (23ºC) 24 hours (23ºC) 24 hours (23ºC) Use temperature 10 ~ 30ºC 5 ~ 35ºC 5 ~ 30ºC Dilution NO Water (max. 20%) DESMOPOL SOLVENT (5 ~10%)     PRIMER PU-1050 PRIMER PUc-1050 Type 100% SOLIDS POLYURETHANE Low temperature 100% SOLIDS POLYURETHANE Density 1.110 kg/m3 1.110 kg/m3 Adherence to concrete > 2 MPa > 2 MPa Maximum substrate humidity 5% 5% Pot life 35 - 50 min (23ºC) 35 - 50 min (15ºC) Time to touch dry +/- 2 hours (23ºC) +/- 2 hours (15ºC) Re-application time 24 hours (23ºC) 24 hours (15ºC) Use temperature 5 ~ 35ºC 5 ~ 15ºC Dilution NO NO     THE RIGHT CHOICE THE DESMOPOL POLYURETHANE AND TECNOCOAT PURE POLYUREA SYSTEMS All you have to do is establish the type of substrate to be treated. We differentiate between “porous substrates” and “non-porous substrates”. In the case of porous substrates in cold environments, priming with PRIMER PUc-1050 is recommended as it is specific for this type of application. In some cases we can use the PIMER EPw-1070 as a vapor barrier with a consumption next to 1 kg/m2 .   SUBSTRATE TEMPERATURE PRIMER POROUS   (concrete, cement, etc.)   5-35ºC PRIMER PU-1050 PRIMER EPw-1070 PRIMER PU-1000* 5 -15ºC PRIMER PUc-1050 NON-POROUS (metal, ceramic, laminate, asphalt, wood, etc.) 3 - 35 ºC PRIMER EPw-1070 * Use only in DESMOPOL systems   THE TECNOFLOOR EPOXY PAINTS SYSTEM In the case of epoxy paint based systems, it all depends on the TECNOFLOOR products used.    FINISHING PRODUCT SUBSTRATE PRIMER TECNOFLOOR Tw-3040 Water-based epoxy coating ANY PRIMER EPw-1070 TECNOFLOOR T-3020 100% solids epoxy coating POROUS PRIMER EP-1020 NON-POROUS PRIMER EPw-1070   CORRECT APPLICATION The steps described below are for guidance purposes only; to ensure correct application we suggest you read carefully the technical specifications for the product, available on our web page.  Prepare the substrate correctly, in accordance with the procedures indicated in the technical specifications. Mix the two components using a mechanical agitator for approximately 2 minutes. Apply one or several coats using a roller or suitable airless equipment until the required thickness is achieved. Wait until touch dry between each coat and do not exceed, in any case, the maximum re-application time. If this time is exceeded, the substrate preparation must be repeated and the process started again. Wait until the drying time has elapsed before continuing to apply the chosen system.   EXCELLENT REPAIR CEMENT In most cases when preparing concrete, it is necessary to fill in unevenness and holes. A “trick” to achieve an excellent and extremely hard repair cement without using any water in the mixture, which avoids retraction and makes it really quick drying, is to mix 1 part of PRIMER EP-1020 resin with three parts of calcium carbonate CaCO3.
