ealing with the origianal moldel, 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 cn pour it into the mold frame. The sillicone mold will cured in 2~3 hours.
Note: the time for vacuum-pumping should be less than 3-5mins, othewise, once the silicone rubber has cross-link
Specifications of silicone potting :
Two parts silicone , applicable to sealing , bonding, coating for electronic parts.
n be used for a long time under the temperature of -60c ~200 c with the characteristic of moisture-proof and waterproof, radiation-proof as well as weatherable and anti-ageing.
2. No significant exothermal or shrinkage during curing.
3. Very stable to changes of temperature, stability over wide temperature range (-50 to 200 oc).

Molding silicone rubber operations:
mould silicone rubber is a kind of flowing liquid, and it consists of two component, part A is aflowable liquid silicone rubber, part B is the curing agent.
Firstly, after your previous work of dealing with the origianal moldel, 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 cn pour it into the mold frame. The sillicone mold will cured in 2~3 hours.
Note: the time for vacuum-pumping should be less than 3-5mins, othewise, once the silicone rubber has cross-link reaction during vacuumizing. it will not be operated.
Liquid silicone rubber for gypsum features
Liquid silicone rubber is two part silicone with general hardness of 22-50a¡ãafter curing with features ------
High tensile & tear strength
High duplication times
Low linear shrinkage
Resistance to high-temperature
Low shrinkage and non-deformation
Resistance to acid-alkali and expansion
Liquid silicone rubber for gypsum operation instructions
Step one: take 100g of part a and add 2g of part b and mix the silicone rubber and curing agent evenly.
Step two: vacuum pumping
Without exception, this step takes less than 10 minutes.
Note: the time for vacuum-pumping should be less than 3¡ª5 minutes , otherwise, once the silicone rubber has cross-link reaction during vacuum pumping process, it will not be operated.
Step three: pouring the mixture into the frame with original gypsum mold slowly .
Shelf life for liquid silicone rubber
10~12months, when stored in a dry & cool place under the room temperature 25.
Packing for liquid silicone rubber
1kg/ bottle , 5 kg/drum vacuumed packing, 25kgs/drum vacuumed packing, 200 kg/drum
25kg /drum or 200kg /drum
