Uses

The polyurethane foam system TECNOFOAM G-2100 can be used in these situations:

  • a complete and continuous coating system in construction, industrial, farming, or agricultural facilities.
  • in applications on asbestos or steel roofs.
  • on vertical walls, ceilings (not subjected to permanent weight)

NOTE: For other applications/situations, please, consult our technical department

GENERAL FEATURES

  • TECNOFOAM G-2100 is a product with high insulating capacity, easy to apply covering all surfaces
  • the application and training is done by our spray equipment TC2049 (spray-equipment.tecnopolgroup.com) or similar
  • the blowing agent is water
  • it is free from harmful to the ozone layer, so do not promote the greenhouse effect (NOT contain HFCs, HCFCs, VOCs, etc ...).
  • TECNOFOAM G-2100 system is 100% recyclable by mechanical means friendly to the environment
  • no gas collection for recycling and/or destruction is required
  • it does not emit any substance to the environment once installed.
  • the properties of this polyurethane foam system allow it to adhere to any surface such as concrete, ceramic, metal, polyurethane foam, wood, acrylic paints or thermal insulation foam(checking the situation of areas recommended).
  • the application of TECNOFOAM G-2100 is a completely continuous system, saving any kind of union between applications, and providing optimum mechanical protection 
  • recommended thickness: 5 -10 mm

PACKAGING

APPLICATION METHOD

In general, you should take the following factors:

  • the application of polyurethane foam system TECNOFOAM G-2100 should be performed under non-presence of moisture or water from the support stand on which to apply either at the time of application as a posteriori.
  • the substrate must be clean and free of dust
  • in applications with high-temperature gradients, a vapor barrier is placed on the warm side of the insulation to prevent condensation
  • perform successive layers of a thickness 1.5~2 cm each, until the desired thickness
  • TECNOFOAM G-2100 adheres firmly to most common materials such as wood, plasterboard, steel, OSB, plywood, cement, inside masonry exterior plaster panels, and construction itself.
  • no shrinkage after performing the expansion.

APPLICATION REQUIREMENTS (spray equipment)

For the formation, it is necessary to mix the two initial liquid components, isocyanates and amines by our spray equipment TC2049 (spray-equipment.tecnopolgroup.com) or similar (proper maintenance and cleaning it is recommended). The general parameters for this material will be the following:

  • Heater isocyanate temperature: ±40-45 ºC
  • Heater amines temperature:±40-50ºC
  • Hose temperature:±40-50ºC
  • Pressure:60-120 Bar

These temperature and pressure parameters have to be valued, ratified, or be varied by the applicator, depending on the conditions of each climate zone, weather situation, or projection equipment specifications.

HANDLING

These safety recommendations for handling, are necessary for the implementation process as well as in the pre and post, on exposure to the loading machinery.

  • Respiratory Protection: When handling or spraying use an air-purifying respirator.
  • Skin protection: Use rubber gloves, remove immediately after contamination. Wear clean body-covering. Wash thoroughly with soap and water after work and before eating, drinking or smoking.
  • Eye / Face: Wear safety goggles to prevent splashing and exposure to particles in the air.
  • Waste: Waste generation should be avoided or minimized.
  • Incinerate under controlled conditions in accordance with local laws and national regulations.

Anyway, consult the material and safety data sheet of the product.

COMPLEMENTARY PRODUCTS

The TECNOFOAM system may be complemented with the following products as a means of protection or to improve its physical-mechanical properties depending on its exposure, the desired finish, or the type of substrate.

TECNOCOAT P-2049 LV: pure low viscosity polyurea. Approximate consumption 2 kg/m²

DESMOPOL: single component polyurethane membrane for waterproof. Approximate consumption 1,5 kg/m²

TECNOTOP 2C: two-component colored aliphatic polyurethane resin used to protect against UV rays, to use after DESMOPOL or TECNOCOAT waterproofing membranes

TECNOTOP 1C/2C: colored aliphatic  resin used to protect against UV rays; to use after DESMOPOL or TECNOCOAT waterproofing membranes
