Development of a high performance hybrid epoxy silicone resin for coatings

Abstract

Purpose

The purpose of this paper is to develop a novel organic‐inorganic (epoxy‐silicone) hybrid resin for application in heat resistant surface coatings.

Design/methodology/approach

Thermally stable aminosilicone resin was prepared by using diethoxydimethyl silane and γ‐aminopropyldiethoxy methyl silane.

Findings

The hybrid epoxy silicone resin shows significant properties such as toughness, chemical resistance and thermal stability.

Research limitations/implications

The prepared amino siloxane was cured by commercially available epoxy resin PG 100 and toluene diisocyanate in different ratios at high as well as at room temperature to develop high‐temperature vulcanisation and room temperature vulcanisation resin systems.

Practical implications

The hybrid epoxy silicone resin may be used as heat resistant coatings due to their low shrinkage and lesser internal stress.

Originality/value

The developed hybrid epoxy silicone resin was novel for application in thermally stable coatings.
