Shin-Etsu KR-510 Epoxy Resin Modifier
Shin-Etsu KR-510 is an organosilicon oligomer specifically engineered for epoxy resin modification, delivering significant improvements in heat resistance and weather resistance. Manufactured by Shin-Etsu Chemical Co., Ltd. of Japan, this product offers excellent compatibility and reactivity, making it ideal for epoxy resin systems requiring high-temperature stability and outdoor durability.
Product Overview
KR-510 utilizes a unique organosilicon structure that chemically reacts with epoxy resin molecular chains, incorporating organosilicon segments into the epoxy network. This chemical modification enhances heat resistance while maintaining stable mechanical properties under high-temperature conditions, and significantly improves weather resistance to effectively withstand environmental factors including UV radiation, heat, and humidity. The product cures without producing small molecule by-products, ensuring system compactness and performance stability.

Key Features
KR-510 features a molecular structure containing both reactive functional groups and organosilicon segments. The reactive groups undergo ring-opening reactions with epoxy groups to form stable chemical bonds, while the organosilicon segments provide excellent flexibility, hydrophobicity, and thermal stability. This design ensures modified epoxy resin maintains high strength and modulus while acquiring the low surface energy, weather resistance, and heat resistance characteristic of organosilicon materials.
The product maintains stable performance across a temperature range of -50°C to 200°C, making it particularly suitable for harsh environment applications including automotive electronics and outdoor equipment.
