Technical Information
Product Description

Colmefoam LHD is a polyurethane spray foam system for the production of rigid foam with closed cells, used for roofs, walls and floor insulation over metal, concrete and plywood. The system is CFC-free and has Zero Ozone Depletion Potential (Zero ODP) value.

 

Colmefoam LHD is a composed of  Polyol Component (A), a mixture of polyol, catalyst, blowing agent and other additives  and Isocyanate-Component (B), a mixture of diphenylmethane- disocyanate, isomers and halogen.

Application Information
Instructions for use

Application:

  • Must be applied using plural-component spray equipment. The mixture reacts on the surface, adhering to it instantaneously, and expanding into a rigid foam
  • Thickness should be between 10-20mm. In order to maintain the designed density and  dimensional stability, it is not recommended to apply thicker layers.
  • Higher than recommended layer thicknesses, cause a decrease in density and worse dimensional stability of the foam. Very thin layers will increase the density and decrease product yield.
  • When applying a total thickness of (>6 cm), it is important to keep a time gap of 10 min between the layers. Longer time gap is necessary for thicknesses above 10 cm.
  • The distance from the spray gun to the substrate is recommended to be approx 80 cm.
Additional Information
Health & Safety

The isocyanate component irritates the respiration sytem, eyes and skin. This can have allergic reactions if inhaled or when comes in contact with skin. The required measurements indicated in the safety data sheet should be noted during handling of isocyanate. The same procedure should also be applied during handling of the A system (polyol) considering the risk available.
