Forming Silicone resin X-40-2667A X-40-2756

Silicone used as a molded product, the product list has a silicone composition of X-40-2667A/B and X-40-2756 which are 100% heat resistant. In particular, X-40-2756 has a higher Tg than conventional products and is excellent in workability because it can be cured in one liquid.

X-40-2667A (two-component addition curing silicone)

Excellent heat resistance

X-40-2756 (one-component addition curing silicone)

Excellent heat resistance and low water absorption
