Description of RTV2 molding silicone for PU resin casting:
RTV2 molding silicone for PU resin casting is general called two-component room temperature vulcanization silicone with excellent fluidity and good operational performance. an elastic RTV2 moulding silicone mould will be obtained with resistance to deformation, high-temperature, acid and alkali and expansion.
Application of RTV2 molding silicone for PU resin casting
A: Cultural relic duplication, architectural decoration, statues
B: Polyester Resin crafts
C: Lighting ornaments, soap, candles molding
D: Plaster, Gypsum, Cement, Concrete decorations
F: Model design, product exploitation, etc.
Features of RTV2 molding silicone for PU resin casting:
(1)high tensile & tear strength
(2) Low linear shrinkage
(3)free Curing agent
(4)brushing & pouring
(5) high duplication times
Operation instructions of RTV2 molding silicone for PU resin casting
Component A is white flowing liquid and component B is the curing agent. For example, take silicone rubber of 100g and add 2g curing agent for mixing evenly (silicone rubber and curing agent must be measured accurately). After the silicone rubber and the curing agent are completely mixed, put the silicon into a vacuum machine for deairing to remove the bubbles. After deaired, pouring the liquid silicone rubber into the product to be duplicated or into the mold frame. If you dont have vacuum machine, please add 1.2% or 1.5% curing agent so that the bubbles can bubble itself. Since the less curing agent you add, the slower the mould will curdle, the bubbles will release out itself.
