  • Patent number: 4740577
    Abstract: A polymerizable composition of polyurethane precursors is rapidly cured using energy-activated catalysts to provide polyurethanes. The polymerizable composition is comprised of polyisocyanates with polyols, fillers, coating aids, adjuvants, and a latent catalyst. Latent catalysts are ionic salts of organometallic complex cations. The cured polyurethanes are useful as abrasion resistant coatings, protective finishes such as furniture finishes and floor tiles, binders for magnetic media, adhesives, and have various applications in industries which use photoresist technologies such as graphic arts and electronics, and in the paint and ink industries.
