Description:
GC RTV silicone SP-8 series a food grade, liquid silicone rubber that was designed specifically for mold making. Unlike many liquid silicones that have complicated mix ratios and very thick consistencies, SP-8 is easy to use because equal amounts of both catalyst and base are combined to produce a silky smooth, low viscosity liquid silicone rubber that reproduces the finest details. A 1:1 mix ratio is very convenient for large projects and also enables moldmakers to easily pour molds that may weigh as little as two ounces.

Appearance:
Part A: a non-toxic and odorless liquid with translucent color and platinum inside
Part B: a non-toxic and odorless liquid with translucent color.
ATT: We can do any curing time as your requirements.
Notice:
What is the hardness should I choose
Normally 5~55 Shore A will be the best, but it also should according to your size and pattern design.
Warm Tips:
The surfaces with which the material comes in contact must be perfectly clean, free of grease and dry.Close the bottles after use so as not to confuse the cap of the catalyst with that of the base when re-sealing.Be aware of possible cross-contamination; it's highly recommended to use only dedicated gear when processing poly-addition RTV2 silicone rubber (including degassing devices).Be aware that contact with certain material can inhibit the curing of the RTV2 poly-addition silicone rubber. Common contaminants to be avoided include:
-Natural or synthetic rubber, vulcanized with sulphur derivatives
-Poly-condensation RTV catalyzed with metallic salts.
-PVC stabilizing agents.-Amine cured epoxies.
-Sulphur, tin and amines derivatives.
-In case of doubt, carry out a small test by pouring the mixture onto a small area of the object.
