What is the reason why the rubber is not cured in the use of hot curing silicone rubber?
The cause of the problem: the catalyst in the glue is toxic or expired; Insufficient curing temperature or time caused by incomplete curing. The cause of the problem may be: because of measuring instrument error or human factors caused by the proportion of glue error; Failure occurs when the product exceeds or is close to the shelf-life;
Reduced efficiency; Failure of catalyst in product or reduction of efficiency due to improper storage during storage; The catalyst may be toxic in the environment when used, such as phosphorus, sulfur, and nitrogen

Organic compounds, or with silica gel at the same time use polyurethane, epoxy resin, unsaturated polyester, condensation type room temperature vulcanized silicone rubber and other products; Insufficient curing temperature or time caused by incomplete curing.
