20150087774 | LIGHTFAST POLYURETHANE COMPOSITION - The present invention relates to a composition comprising 10 to less than 50 wt.-% of at least one oligomeric polyisocyanate a-1) based on hexamethylene diisocyanate and more than 50 to 90 wt.-% of at least one polyisocyanate a-2) based on isophorone diisocyanate, comprising monomeric isophorone diisocyanate and at least one oligomeric isophorone diisocyanate, and an isocyanate-reactive component selected from the group consisting of polyester polyol, polyether polyol and mixtures thereof. It has been shown that the above mentioned mixture of the specific isocyanate group containing components improves the thermal and mechanical properties of a cured composition. Thus prepared molded articles are particularly suitable for the preparation of spectacle lenses, inter alia due to these properties. | 03-26-2015 |
