According to the customer request to deal with the curing agent and the proportion of adding silicone rubber, if the customer requires fast curing, quick release will add curing agent, condensation silicone add curing agent don't more than 5%, the largest proportion of curing agent added the faster reaction rate, the greater the amount of silicone if silicone rubber has curing with curing agent did not stir well, it will waste of raw materials.
On the contrary, if the pouring mode is required, the curing agent must be added less and the adhesive time of silicone rubber will be extended so that the perfect mould can be made. The proportion of curing agent and silicone rubber is not less than 1%. If the curing agent is too small, it will not solidify for a long time. The curing agent can add no more than 5% to the hardness, tension and tear strength of silicone rubber .
