CHEMICAL-RESISTANT VERY FLEXIBLE POLYURETHANE PLASTICS AND COATING AND PRODUCTION THEREOF

CHEMICAL-RESISTANT VERY FLEXIBLE POLYURETHANE PLASTICS AND COATING AND PRODUCTION THEREOF

A process for the preparation of highly elastic, chemicals- resistant polyurethane plastics, in particular surface coatings, involves reacting a) a polyisocyanate component with b) a polyol component which is essentially a liquid polybutadiene resin having a molecular weight in the range from 500 to...

Zusammenfassung:A process for the preparation of highly elastic, chemicals- resistant polyurethane plastics, in particular surface coatings, involves reacting a) a polyisocyanate component with b) a polyol component which is essentially a liquid polybutadiene resin having a molecular weight in the range from 500 to 10,000 and containing terminal hydroxyl groups, c) water in an amount from 10 to 50% by weight, based on the weight of component b), d) alkaline earth metal hydroxides or oxides in an amount of from 20 to 500% by weight based on the weight of component b), if desired in addition to further inorganic assistants and additives, and, if desired, e) organic assistants and additives.
