·Environmental protection and non-toxic, SGS, Rosh environmental protection and non-toxic certification.
·It has excellent electrical and chemical stability, water resistance, ozone resistance, weather aging resistance, non corrosiveness, physiological inertia, non-toxic and tasteless, low linear shrinkage, easy to operate, etc.
Purpose
Silica gel is a two-component addition molding liquid silicone rubber, which has the advantages of good dimensional stability and good demoulding performance. It has a heat resistance of more than 250 ° C. It is widely used in resin drilling accessories and gem like products of rapid prototyping.
It is often used to make molds for casting epoxy resin, polyester resin, polystyrene, vinyl plastic, paraffin, low melting point alloy concrete, etc. it is also used to copy cultural relics and arts and crafts.
usage and precautions
·Mix component A and component B evenly according to the weight of 10:1, and then pour them after vacuuming. Heating 60-120 degrees, can be fully cured in a few minutes.
·During operation, it should be separated from the container using overcondensated silica gel, and the silica gel should be operated with the unused silica gel tool at room temperature
