THIXOTROPIC AGENT THAT CAN BE ACTIVATED USING ACTINIC RADIATION, A METHOD FOR ITS PRODUCTION AND THE USE THEREOF

摘要

A novel thixotropic agent comprising urea crystals which comprises at least one compound containing at least one functional group having at least one bond which can be activated with actinic radiation; a novel process for preparing a thixotropic agent comprising urea crystals by reacting at least one primary and/or secondary amine and/or water with at least one polyisocyanate in a liquid organic medium consisting of or comprising at least one compound containing at least one functional group having at least one bond which can be activated with actinic radiation; and the use of the thixotropic agents to prepare coating materials, adhesives and sealing compounds curable thermally and with actinic radiation.
