Uses

The polyurethane foam system TECNOFOAM G-2060 HFO can be used in these situations:

  • It’s specifically designed for thermal insulation in construction, industrial, farming or agricultural facilities.
  • In applications where flat roofs, interior floors, and installations with a floor heating system, all those with high compression needs on the surface. (including vehicular traffic)
  • It is specially designed to be coated with TECNOCOAT P-2049, without the appearance of bubbles, "pinholes" or other pathologies.

PACKAGING

Metal drums of 250 kg for the isocyanate and 230 kg for the polyol side

SHELF LIFE

POLYOL COMPOUND: 3 months

ISOCYANATE COMPOUND: 6 months

Always store the drums before use at a temperature between 5 ºC and 35 ºC, always in dry areas, without the possibility of humidity entry, and without direct contact with the sun or sources of heat. Very low temperatures increase the viscosity of the polyol which makes it difficult to mix and apply, and in the isocyanate they can generate crystallisations, which can cause its mixing ratio to vary and the consequent internal problems in the mixing and application equipment.

Very high temperatures can modify polyols, causing  loss of the blowing agent, increasing consumption and producing the swelling of the metallic drum. To avoid these last situations, it is recommended to let the drums rest for a while before use, in a cool and ventilated place.

APPLICATION METHOD

In general, you should take the following factors:

  • the application of polyurethane foam system TECNOFOAM G-2060 HFO 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
  • minimum recommended surface temperature: 5ªC
  • 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 2~3 cm each one
  • wait to apply the second layer, until minimum temperature on the first layer 40-50ºC
  • TECNOFOAM G-2060 HFO adheres firmly to most common materials such as wood, plasterboard, steel, OSB, plywood, cement, inside masonry exterior plaster panels, and construction itself.
  • not shrinkage after performing the expansion.
  • reactivity times (in laboratory conditions):
    • REACTING TIME: 3-5 seconds
    • EXPANDING TIME: 9-12 seconds

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:1.700-2.000 psi

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 as 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.
