Preparation and surface properties of silicone-modified polyester-based polyurethane coats

Article

Abstract

A series of novel silicone-modified polyesters (SPE) were prepared by substituting part of diol with low molecular weight hydroxyl-terminated poly(dimenthylsiloxane) (PDMS). Then, isophorone diisoclanate (IPDI) as hard segments and 1,4-butanediol as chain extender were added to SPE to prepare a silicone-modified polyurethane (SPU). The effects of the type of diol, diacid, and hydroxyl-terminated PDMS, and the amount of hydroxyl-terminated PDMS on the preparation and surface properties of SPU were investigated. It was found that the amount of PDMS incorporated into a polyester chain was relatively higher when 1,6-hexanediol (HDO) and 1,10-decandiol (DDO) were used as diol and the PDMS with lower molecular weight was used as organosilicone compound. Consequently, the SPU coats with HDO as diol, adipic acid (AA) as diacid, and short chain PDMS as silicone segment had the lowest surface-free energy since it had the highest and most homogeneous distribution of silicone segments at its top layer surfaces.
