Application cases of epoxy double seals:
Electronic and electrical potting glue: For example, in the potting of the power module of the computer motherboard, the epoxy-terminated polysiloxane potting glue synthesized by epoxy double seals can effectively protect the internal circuit from dust and moisture erosion, ensure stable operation under different temperature environments, and improve the service life of the motherboard.
Aerospace coatings: The epoxy resin modified by epoxy double seals is added to the outer surface coating of the aircraft fuselage, which enhances the weather resistance, corrosion resistance and adhesion of the coating, can resist the friction caused by complex high-altitude climate and high-speed flight, and maintain the appearance and performance of the fuselage.
Automotive parts bonding: The bonding of the automobile engine hood and the body uses the epoxy double seal as the epoxy resin dilution modifier to prepare the adhesive, which reduces the viscosity and facilitates construction while ensuring the bonding strength and temperature resistance, so that the engine hood is firmly bonded.
Photosensitive dry film materials: In photosensitive dry film materials, epoxy double heads can react with aminostyrene to prepare plasticizers, participate in the polymerization reaction of the dry film system, introduce flexible - si-o-si - chain segments and rigid benzene ring structures, strengthen and toughen the dry film, and improve its tensile strength and other properties.
Fabric finishing agent: When preparing acrylate-modified block silicone oil, the product of epoxy double heads and linear diamine amination can be used as amino double heads to participate in the reaction. The obtained block silicone oil is used for fabric finishing, which can give the fabric softness and smoothness.
