METHOD FOR PREAPARING POLYORGANOSILOXANE MODIFIED UREA-ACRYLATE COMPOUND, POLYORGANOSILOXANE MODIFIED UREA-ACRYLATE COMPOUND PREPARED THEREBY AND COATING COMPOSITION COMPRISING THE SAME

摘要

Provided is a method for manufacturing polyorganosiloxane-modified urea acrylate, comprising the following steps: manufacturing a urea compound by having a compound including amine groups on both ends represented by chemical formula 1 and including a dialkyl siloxane chain, reacted with a cyclic oligomer of a diisocyanate compound represented by chemical formula 2; and having an acrylate-based compound having a hydroxyl group on the terminal or an acrylate-based compound having an amine group on the terminal, reacted with the urea compound. Additionally, provided are a polyorganosiloxane-modified urea acrylate compound manufactured by the method, a coating composition including the same, a high hardness film coated with the coating composition, and a product protected by the high hardness film.
