The advantages and disadvantages of the three kinds of room temperature vulcanization silicone rubber: the advantage of single-component room temperature vulcanization silicone rubber is that it is easy to use, but the deep curing speed is more difficult; the advantage of two-component room temperature vulcanization silicone rubber is that it does not emit heat during curing and has a small shrinkage rate , No expansion, no internal stress, curing can be carried out at the same time inside and on the surface, and deep vulcanization is possible; the vulcanization time of addition-molded room temperature vulcanized silicone rubber is mainly determined by the temperature, so the vulcanization speed can be controlled by adjusting the temperature.
