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- diisocyanate, isomers and halogen.

Packaging, Coverage / Consumption

Part A : 220 Kg
Part B : 250 Kg

Shelf Life & Storage

Before the usage, the system should be made homogenous by mixing. The empty tank should be clean. More detailed information can be obtained from MSDS.

Materials must kept sealed and closed in covered shaded area.

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.
