RTV2 Condensation Cure Liquid Silicone Rubber Corrosion Resistant Long Service Life For Resin Craft Candle Molds
Description of Tin Cure Silicone Rubber
HN-620 A/B is a two-part liquid silicone system with a standard mixing weight ratio of 100:2, which cures fully under ambient temperature conditions.
Feature of Tin Cure Silicone Rubber
1. Suitable viscosity to adapt to pouring or brushing molds.
2. No oil output
3. Good tear resistance and easy demolding
4. Can replicate very fine patterns
5. Multiple times of mold flipping
6. Stable chemical resistance, heat resistance, corrosion resistance, and aging resistance.
7. Low shrinkage rate
8. Shelf life of 12 months
Operation method:
1. Mix the mold adhesive and curing agent in a weight ratio of 100:2-3 and stir evenly;
2. Place the mixed and stirred silicone gel into a vacuum machine for vacuum exhaust bubble treatment. The advantage of doing so is to make the product smooth and free of bubbles (without a vacuum machine, the curing time can be extended to allow bubbles to naturally discharge, but the effect is not very ideal);
3. Spray (apply) a layer of release agent on the already made mold and mold frame, fix the mold in the middle, and slowly and steadily pour the liquid silicone that has discharged the bubbles into the mold frame until the silicone completely covers the mold, and then let it rest until it fully solidifies;
4. Wait until the silicone gel of the mold is fully cured before demolding, and remove the silicone mold for edge treatment;
5. It is recommended to leave the silicone mold for 24 hours before putting it into use, in order to achieve the best use effect of the mold.
