Preparation of Low Free TDI Polyurethane Crosslinker

Xuefen Zhang

Abstract

A low free TDI polyurethane crosslinker,through catalyst polymerization technology,has been prepared.The influence of catalyst level,and temperature and time of reaction on the content of free TDI was discussed.The pilot and scale production results have shown that this technology will reduce the free TDI content dramatically without influencing on other properties of the product.
