Addition Cure Silicone Rubber
Description Addition cure silicone rubber:
Addition cure silicone rubber is generally named two-components 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:
Addition cure silicone rubber 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.

OPERRATING INSTRUCTION of Addition cure silicone rubber:
1. Stir part A and part B with right mixing ratio (1:1) evenly. And get the mixture for vacuum-pumping. (If there is no vacuumizer, you can just pour the mixture slowly from the corner so that less bubbles caused)
2. Enclose the product (the original model) with four plastic plates or wooden plates.
