Product Name: Tin Cure Silicone for Concrete/Cement/Stone Moldmaking
Product Model: XB-725#, XB-730#, XB-735#, XB-740#
Product Description:
The Silicone Rubber items above are the kind of liquid RTV condensation cure for mold making with two parts, part A is the silicone rubber base, part B is the condensation curing agent.
And the last two numbers means the hardness. Usually, the silicone with medium hardness would be choose to make mould for the Concrete/Cement/Stone, or artificial stone, culture stone, concrete stamping or paving.
The mixing ratio is 100:3, and generally 3% free catalyst would be offered. But in the same mixing ratio, the higher the temperature is, the faster the silicone rubber would be cured. So, please add the catalyst accordingly.
