Liquid silicone for mold making is High temperature resistance, acid and alkali-resistance, aging resistance,Low shrinkage, high hardness and no-deformation,High tensile and tear strength, easy to de-molding.
This silicone is used for sculpture, cement / gypsum product, architectural and furniture elements,resin crafts, casting wax, art objects
How to use:
1.A and B must be mixed evenly into a clean plastic or metal container, The bottom and walls of the container must be scraped well to ensure that the silicone is mixed with the curing agent.
2.The pre-operation time of the mixed is 30-40 minutes at room temperature, and the product prototype is poured by vacuum defrosting.The product can be cured completely at room temperature of 3-4 hours and heated at 80-120ºC for 30 minutes.
3.At 25ºC, A/B is fully mixed and stored safely for 30-40 minutes.The higher the temperature, the shorter the storage time.
Package: 10KG, 20KG, 25KG, 200KG or according to customer requirements
