摘要:
The invention relates to NCO-functional prepolymers prepared from dicyclohexylmethane diisocyanate (H12MDI hereinafter) and polyether polyols, with a reduced tendency to crystallization, a fraction of the H12MDI being blended with further monomeric isophorone diisocyanate (IPDI hereinafter), so making it possible to reduce or prevent entirely the tendency to crystallization, and also to the preparation and use.
摘要:
The invention relates to water-soluble or water-dispersible, hydrophilic polyisocyanates and polyisocyanate mixtures, to a process for preparing them, and to their use as a starting component in the production of polyurethane polymers, more particularly as crosslinkers for water-soluble or water-dispersible film-forming binders, adhesives binders, or sealant binders or binder components with or without groups which are reactive towards isocyanate groups.
摘要:
Provided is a coating material comprising a crosslinker component and a catalyst component, the coating material curing at temperatures of 10 to 80° C., to the use of the coating materials to coat a variety of substrates and to coating compositions comprising coating material.
