Epoxy‑terminated Diphenyltrisiloxane

Name: Epoxy‑terminated Diphenyltrisiloxane
Brand: Siwin
Rating: 5.0 (60 reviews)

Siwin‑EP279 is epoxy‑terminated diphenyltrisiloxane, a diphenyltrisiloxane functionalized with glycidyl epoxy groups at both chain ends.

It acts as a high‑performance toughening modifier for epoxy resin, polyurethane and polycarbonate systems. This product can take part in curing and polymerization reactions, greatly enhancing mechanical‑physical performance of finished materials, lowering cohesive energy, and imparting copolymers with outstanding high‑low temperature shock resistance, water resistance, weather resistance, electrical insulation and atomic‑oxygen‑resistant capability.
