Operation instruction of Price of RTV platinum liquid silicone rubber raw material for molding
1. Pls clear the model and tool totally before operation to prevent cure inhibition.
2.Weigh the two part correctly by electronic weight in two separate container .
3. Mixing the two part in 1:1 and stir part A and part B evenly in 2-3 minutes .
4.And get the mixture for vacuum-pumping for de-air the bubble in around 2-3 minutes . (If there is no vacuum machine, pls pour the mixture carefully and slowly down the side of the mold frame so that less bubbles caused)
5. Enclose the product (the original model) with four plastic plates or wooden plates.
6. Clean your products and brush a layer of release agent(detergent or soap water) on your product.
7. Pour the vacuumed mixture into the model frame from the side of the mold frame .

Notice: As our it is platinum cure silikon , which is very easy to cause cure inhibition , so pls do remember thoroughly clean the model and tool before operation . Besides , pls avoid the liquid silikon contact or mix with the following material , otherwise the silikon won’t be cured :
1. Liquid condensation silikon ( condensation silikon not completely cured or organic tin compounds )
2. Sulphur, sulfide and sulfur rubber materials.
3. Amine compounds as well as contains the amine materials.
4. Pewter solder flux.
