Rubber & Products

Description Addition cure silicone rubber:
E642# addition molding silicone is generally named two-component silicone rubber, Part A and part B. It features an exceptional fluidity and good operability. The mixing ratio is 1:1, mainly be suitable for making molds application.
E-642 addition cure silicone rubber is mainly used for molds making for food grade products. And it is also develop to solve the problem of not lighting of the candles and the problem of sticky and white stains on the surface of cement & stone products.

Applications of Addition cure silicone rubber:
E642# addition molding silicone could be mainly used for making concrete stones, precision molds, PU molds, resin molds, gypsum casting, candle molding,for life casting, fabric finishing, seal for electronic components and solar circuit board, trademark decoration. etc.

FEATURES of Addition cure silicone rubber:
1. Two-parts, flowable liquid silicon & curing agent.
2. Can solve the problem of not lighting of the candles and the problem of sticky and white stains on the surface of cement & stone products.
4. It gets cured at room temperature 25 0C within 5-7 hours.
5. An exceptional fluidity and good operability, easy to be demolded.
6. Suitable for pouring methods of operation for small sized molds making.
