MATERIALS:

One-component polyurethane adhesive-sealer, supplied in plastic packaging
Grey/White color
Adheres well to many building materials. Resistant to water, cleaning agents, oils, acids and diluted bases
For insulation and sealing inside and outside
Cured sealer is resistant to moisture, UV radiation and weather conditions
Class E reaction to fire acc. PN-EN 13501-1+A1:2010.

INSTALLATION:

The surfaces on which the application is made must be clean, dry, free from water and dirt, oil, grease or rust
Glass, metal and other non-porous surfaces must be free of painting layer and cleaned with a solvent
Adhesive-sealer should be applied using suitable injection gun by smoothly moving the nozzle along the gap. Steady application prevents formation of air bubbles
Wide gaps should be filled in two steps, by pre-covering both walls of the gap, and then filling the middle part of the gap
Completely cured adhesive-sealer can be painted with dispersion paints
Uncured adhesive-sealant can be removed with crude oil. Cured can only be removed mechanically. Hands can be cleaned with Premium Cleaning Wipes
Detailed information on storage, transport and safety are available in the safety data sheet (SDS).
