How to use
* Liquid silicone rubber is a two-component liquid silica gel material, which is divided into component A and component B. The mixer (injection molding machine) fully mixes component A and component B in an accurate 10:1 ratio.
* Due to the needs of product design, it will be equipped with the operation of color pump and color metering part. After the injection machine,It will be hydraulically extruded from two pipes a and B, it will be merged into a pipe AB and mixed evenly with each other for injection.
Storage and Caution
1.Shelf life: 12 Months.
2.Store in a cool dry place out of direct sunlight.
3.Do not contact with any organic compounds such as N, P, s, Sn, Pb, RG, Bi, as plasma compounds when operating the addition Liquid silicone rubber, otherwise it will cause the curing agent poisoning, cause the curing agent poisoning, and cause the phenomenon that the silicone will not cure.
