RTV silicone rubber for making gypsum cornice mould

Product Description Product Description of RTV silicone rubber for making gypsum cornice mould: RTV silicone rubber for making gypsum cornice mould is generally named as two-parts silicone rubber that is vulcanized at room temperature, and used for model designing work of all kinds of products with simple or intricate patterns.     Appearance of RTV silicone rubber for making gypsum cornice mould :
Part A: Silicone rubber is a white liquid Part B: Catalyst is a non-toxic and odorless liquid, with transparent color. ATT: We can provide fast/medium/slow catalyst of for hot, warm or cold season.   Features of RTV silicone rubber for making gypsum cornice mould :
Amazing fluidity and easy to operate Complex design available Not Oily Stable quality, non-toxic and odorless catalyst provided Easy de-molding Excellent tension and tear strength High performance in duplication Shrinkage is almost zero (below 0.2) Excellent resistance to weather, temperature, aging, acid and aging-proofing.   Operation Methods of RTV silicone rubber for making gypsum cornice mould:
2 part silicone for making gypsum cornice mould is a kind of flowing liquid, and it consists of two components, part A is a flow-able liquid silicone rubber, part B is the curing agent.   1. Firstly, after your previous work of dealing with the original model, take some liquid silicone rubber, add 3% curing agent of the amount of silicon and mix them evenly. 2. Then after vacuum pumping the mixture, you can pour it into the mold frame. 3. The silicone mold will be cured in 3 to 5 hours       Technical Data: Notes: 1.The data are based on the operation under room temperature of 25℃. 2.The data-sheet of viscosity, hardness, working time, curing time can be adjusted according to your requirement
