Some customers ask how liquid silicone should also be vulcanized, is it necessary to use sulfur?The answer is no, there is no need for sulfur, vulcanization is just by natural rubber vulcanization need sulfur, habitual name, liquid silica gel should be normal called curing.How to solve the problem of liquid silicone vulcanization?

    There are two main problems with liquid silicone vulcanization:

    One is that it becomes solid before being vulcanized and can no longer be used. This occurs in the single component liquid silica gel, the main reason is that the condensation type single component liquid silica gel is not sealed well, in the air vapor curing, or the added liquid silica gel is not stored at a low temperature or placed for a long time, leading to advance curing.

    The second is unable to cure, condensation liquid silica gel can not cure the reason may be too little curing dose or placed too long the curing agent volatilized.The reason that the liquid silica gel can not cure may be catalyst poisoning or curing temperature, time is not enough. If the catalyst is poisoned, apply Vaseline and other materials to the contact area.
