Cast stone moulds RTV silicone mould making rubber
1. Applications of Cast stone moulds RTV silicone mould making rubber
RTV silicone mould making rubber could be mainly used for making concrete stone molds,garden statue molds,statue molds,stone mold,concrete statue mold,candle mold, 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.
2.Description of Cast stone moulds RTV silicone mould making rubber
RTV silicone mould making 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. It is very user friendly and will cure at room temperature over virtually any surface.
3.How to making silicone molds with rtv silicone mould making rubber
a. 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)
b. Enclose the product (the original model) with four plastic plates or wooden plates.
c. Clean your products and brush a layer of release agent(detergent or soap water) on your product.
e. Pour the mixture with correct mixing ratio into the model frame.
After about 2-4 hours, when the silicone cured, get out the original model, and there you get a finished addition cured silicone mold .
SHELF LIFE: Twelve (12) months from date of shipment when stored at 24°C in original unopened packages.
