Polyurethane Systems for building and industry

Polyurethane systems with high fire resistance

Polyurethane systems with high fire resistance offer a totally safe insulation in building construction, both structurally speaking and for the safety of its occupants. The false myths surrounding this type of insulation must not be taken into account as shown by the different tests that have been carried out.

 Synthesia Internacional is a manufacturer and distributor of polyurethane systems that provide multiple applications in the construction sector and other relevant sectors such as the industry. Next, we are going to present our products with high fire resistance, accredited by means of a test certificate that shows the maximum thicknesses in order to comply with the different classifications according to the conditions or final applications of use.

Poliuretan® Spray RF-351-C

Poliuretan Spray RF-351-C is a two-component polyurethane system containing HFC’s and formulated to obtain closed-cell rigid foams to be sprayedin-place for thermal insulation. It is applied by spraying with a high pressure equipment fitted with heating, with a mixing ration of 1:1 in volumen.

The main applications are the thermal insulation of building closings, houses (partitioning), industrial buildings, roofs, farms, ships, tanks, cool stores, etc.

Protection of the foam

Rigid PUR foams applied outdoors are darkened and brittle by the action of UV radiation. Thus, all foams that are to be used in these conditions must be protected with a suitable coating (acrylics, butyl rubber, vinyl, asphalt, mono and bi-component polyurethanes, etc.)

Synthesia Internacional, supplies an acrylic coating AQ 3300 and urethane bi-components URESPRAY F-75.

The ideal coating is one which meets the following requirements:

  • Physical properties:
    • Resistance to atmospheric and chemical agents.
    • Good tensile strength.
    • Good foam adherence.
    • Resistance to UV radiation.
  • Regarding the application:
    • Fast drying.
    • Possibility of spray gun application.
    • Minimum thickness 0,5-1,0 mm.
