2-part Moulding rubber silicone for GRC mouldings
Introduction of RTV silicone:
It is generally called Two-part of RTV 2 molding silicone rubber , part A is a kind of flowable liquid silicon ,part B is catalyst..
Cured at room temperature within 2-4 hours.
Application of RTV silicone:
It is mainly applied for making various molds:
1. Reproduce concrete or cement, gypsum, gypsum, architecture, decorative arts and crafts, big statue, cultural relic product, etc.
2. Reproduce poly resin, epoxy, polyurethane-polymer, plastic toy, gift and stationery.
3. Reproduce soaps, candle & lighting.
FEATURES of RTV silicone for decorative grc moulding concrete statue molds:
1.Exceptional fluidity and good operability.
2.Good Temperature and deformation resistance as well as low shrinkage.
3.High duplication times.
Operation step for liquid RTV silicone for GRC mouldings concrete statue molds:
Step One to use RTV 2 molding silicone rubber: Take 100g of part A and add 2g of part B and mix the silicon rubber and the curing agent evenly.
Step Two to use RTV 2 molding silicone rubber: vacuum pumping
Without exception, this takes less than 10 minutes. Otherwise, it will cause cross linking reaction, and no more further steps will be available.
Step Three to use RTV 2 molding silicone rubber: Brushing cast & Perfusion Molding operation.
