Some manufacturers in order to save costs, the use is not environmental protection, low price of ordinary curing agent, rather than completely through the ROHS detection of environmental protection odorless curing agent, curing agent is a kind of catalyst to promote silicone raw materials curing molding, after the product will volatilize, there will be only a small part of residual, 48 hours will volatilize, Vulcanizing machine will not harm human products, but cheap vulcanization opportunity to produce a burnt pungent taste, volatile time in about a month, so in the choice of silicone gifts, products as far as possible to choose better performance of tasteless silicone products. Especially silicone kitchenware, more stringent requirements. Glue basically does not have a great taste, taste is the problem of curing agent, curing agent selection of unscented double 25, and then two paragraphs basically no smell, do not use DCP. There are two vulcanization time please do not choose 200 degrees. 155 degrees or 150 degrees. Bake for 12 hours. If the temperature is too high. Products age easily. The quality is not guaranteed.
