Research progress in improving adhesive property of addition-type liquid silicone rubber

Abstract

The research on improving the adhesive property of addition-type liquid silicone rubber to the substrate at home and abroad in recent years were reviewed with 28 references, and those researches mainly included surface treatment of the substrate, introducing functional groups into the polyorganosiloxane molecular chain, adding adhesion promoter containing functional groups, and adding primer coat layer between the rubber and the substrate, and the advantages and disadvantages of various methods were also analyzed. What′s more, it was pointed out that the development direction of the research on the adhesion performance of addition-type liquid silicone rubber in the future was the development of various functional adhesion promoters.
