METHOD FOR USING URETHANE RESINS

摘要

A method for curing an isocyanate group-containing compound, which comprises treating with a tertiary amine in a vapor-phase state an isocyanate compound having in one molecule not less than two isocyanate groups linked to an aromatic nucleus through a methylene group or an isocyanate-terminated urethane resin obtained by the reaction thereof with an active-hydrogen contain-ing compound. The isocyanate compounds or isocyanate-terminated urethane resins are allowed to cure and dry for a shortened period of time ranging from about 1 to 10 minutes, thus providing high-speed curing. The method of this invention can be advantageously employed in the fields, such as continuous painting step ant printing step etc.
