Abstract
Allyl carbamates are disclosed. The allyl carbamates are prepared by reacting an isocyanate with an allylic alcohol or alkoxylated allylic alcohol. Suitable isocyanates are selected from hexamethylene diisocyanate (HDI), HDI biuret, dimer, HDI trimer, HDI allophanate, isophorone diisocyanate (IPDI), IPDI trimer, IPDI allophanate, bis(isocyanatocyclohexyl)methane, and mixtures thereof. The allyl carbamates have at least two allyl functional groups per molecule. UV-curable and air-drying coatings formulated from the allyl carbamates show excellent chemical resistance and physical properties.
