DESCRIPTION of Silicone Rubber for GRC Mold Making
Stone Concrete & GRC Casting RTV 2 Silicone is generally named as two-part room temperature cure silicone rubber, which features an exceptional fluidity and good operability. When mixed with 2% curing agent, they can still be operated within 30 minutes, but will be formed after 4-6 hours. With resistance to deformation, high temperature, acid and alkali, and expansion.
APPLICATION of Silicone Rubber for GRC Mold Making
A: Cultural relic duplication, architectural decoration, statues
B: Resin crafts
C: Lighting ornaments, candles
D: Plaster, Gypsum, Cement, Concrete decorations
F: Model design, product exploitation, etc.
FEATURES of Silicone Rubber for GRC Mold Making
Good flowability and long working time
Medium hardness with high duplicate times
High tear and tensile strength
Easy de-mould from complex replica parts
Acid and alkali-resistance
Low linear shrinkage
INSTRUCTIONS of Silicone Rubber for GRC Mold Making
1-Take 100g of part A and add 2g of part B and mix the silicone rubber and curing agent evenly.
2-vacuum pumping
Without exception, this step takes less than 10 minutes. Otherwise, it will cause, and no more further steps will be available
3-Pouring mold or block mold of silicone rubber
The pouring way is an easy way to make molds, it's slowly and evenly pour into the mixed silicon rubber into the square frame. After the cross linking reaction.
STORAGE of Silicone Rubber for GRC Mold Making
Liquid RTV 2 Moldmaking Silicone Rubber is an environmentally-friendly liquid silicone product, is not easy to burn and can be stored and transported as non-hazardous goods. The shelf life of the product is about one year from the date of production. Inspection is required when exceeding the time limited. It can continue to be used in case of neither thickening nor deterioration.
