TWO-COMPONENT POLYURETHANE COMPOSITION WITH DELAYED CROSSLINKING |
摘要 |
The invention relates to a crosslinking two-component polyurethane composition consisting of (i) a constituent A containing polyols and additives, and (ii) a constituent B containing between 100 and 65 wt. % of aromatic polyisocyanates, between 0 and 35 wt. % of aliphatic polyisocyanates, and between 0.05 and 3.0 wt. % of a retarder, and optionally additives, the mixed composition having a viscosity (EN ISO 2555) of between 100 mPas and 3000 mPas at 25°C, and the crosslinked composition having a glass transition temperature (Tg) of higher than 50°C and a pot life of longer than 60 minutes. The two-component polyurethane composition is suitable as an adhesive and as a matrix substance for composite materials. |
