Renewable-based polyol for low temperature elastic PU coatings

[image_0]As a main feature, the new polyol offers very high elongation values also at low temperatures while maintaining its good tensile strength. According to Alberdingk Boley, thanks to the low glass transition temperature, it is even possible to achieve an elongation at break of approximately 400 % and a tensile strength of 15 N/mm2 at a temperature of -20 °C. By crosslinking with an appropriate aromatic polyisocyanate, PU coatings and adhesives with outstanding crack-bridging properties can be formulated. These can be used especially for car park deck coatings, sealings or flooring solutions, which need to be resistant to cold temperatures. Albodur 904 is a hydrophobic polyol with low viscosity and offers good deaeration and workability properties, says the company. Alberdingk Boley at the ECS 2015, hall 7, stand 455
