Development of a high performance hybrid epoxy silicone resin for coatings
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
?-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.
