RTV-2 Silicone raw material for gypsum mold/resin/concrete operations:
Molding silicone rubber is a kind of flowing liquid, and it consists of two component, part A is a flowable liquid silicone rubber, part B is the curing agent.
Firstly, after your previous work of dealing with the original model, take some liquid silicone rubber, add 2%~3% cuing agent of the amount of silicon and mix them evenly.
Then after vacuum-pumping the mixture, you can pour it into the mold frame. The silicone mold will cured in 2~3 hours.
Notes of RTV-2 Silicone raw material for gypsum mold/resin/concrete:
The time for vacuum-pumping should be less than 3-5mins, otherwise, once the silicone rubber has cross-link reaction during vacuumizing, it will not be operated.
RTV-2 Silicone raw material for gypsum mold/resin/concrete with FOQ:
Why does the mold made of silicone rubber have an unsmooth surface with tracks and strips on it?
It is due to product or model to be molded should hasn't been sanded or polished . If the mold or product is not sanded or polished, the mold made of whatever quality silicone rubber will not be good and smooth enough since the mold or the product itself is not smooth or perfect. Another case is that uneven brushing of the release agent will also bring about unsmoothness of the mold.
