PACKAGING

Metal drums of 250 kg for isocyanate side, and 230 kg for the poliol side.

SHELF LIFE

POLYOL COMPOUND: 3 months

ISOCYANATE COMPOUND: 6 months

Temperature within 5 ºC ~ 35 ºC, provided it is stored in a dry place, nondirect contact with the sun.

APPLICATION METHOD

In general, you should take the following factors:

  • the application of polyurethane foam system TECNOFOAM I-2035 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
  • SHAKE STRONGLY POLYOL COMPONENT, TO SO ENSURE THE UNIFORMITY
  • injecting the mixed product through the reactor equipment, through perforations located on the element to be insulated.
  • consider that the time of expansion of the two components, once mixed is one 25 ~ 30 seconds.
  • repeat this action as many times as necessary to fill the entire element

APPLICATION REQUIREMENTS (reactor equipment)

For the formation of TECNOFOAM I-2035 HFOpolyurethane foam, it's necessary to mix the two components, polyol and isocyanate, through specialized reactor equipment. (Proper reactor equipment maintenance and cleaning it's necessary too). Stir the polyol component before the mixing, is recommended.

The most general parameters of this equipment are as follows:

  • Heater isocyanate temperature: 40~45 ºC
  • Heater amines temperature:±35~45ºC
  • Hose temperature:± 35~45 ºC
  • Pressure:>1200-1600 psi( the exact pressure depends on the kind of needs of the application)

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
