Description

(Epoxycyclohexylethyl)Methylsiloxane - Dimethylsiloxane Copolymer, Viscosity 650-800 Cst is a specialized reactive silicone copolymer engineered to deliver enhanced adhesion, flexibility, and chemical resistance in demanding formulations. This product is valued for its unique combination of a reactive epoxy-functional siloxane backbone with the classic properties of polydimethylsiloxane, creating a versatile performance additive. It is primarily sought by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in advanced composites and release agent formulations, where it acts as a key modifier to improve material performance.

Application

• Adhesion Promoter: Enhances the bonding of coatings, inks, and adhesives to low-surface-energy substrates like plastics and metals.
• Coatings Modifier: Imparts improved flexibility, scratch resistance, and weatherability to industrial and protective coatings.
• Sealant & Elastomer Formulation: Used as a reactive intermediate or additive to modify the mechanical properties and chemical resistance of silicone-based sealants and elastomers.
• Release Agent Component: Serves as a key ingredient in premium solvent-based or solventless release coatings for pressure-sensitive adhesives.
• Composite Material Additive: Improves the interfacial adhesion between fibers and resin matrices in advanced composite materials.
• Lubricant & Surface Treatment: Provides a durable, low-friction, and protective surface layer on various materials.
