Precautions for the use of silicone foam rubber sheets

Using silicone rubber foam board should be very careful, because improper use may affect the normal effect of silicone foam board. Next, we will briefly explain how to use foam silicone rubber sheet properly and reduce the influence of human factors.

First, in order to avoid uneven distribution of some raw materials, it is necessary to thoroughly stir the raw materials before use.

Second, mix the raw materials and curing agent in the correct proportion, stir at a constant speed for 120-180s to ensure uniform mixing of various materials.

Third, vacuuming the mixed product, in order to reduce the impact of solidification on normal production, and it should be used as soon as possible.

Fourth, the materials are mixed in the correct ratio and cured according to the specified curing temperature and curing time. Refer to the following: The curing agent and raw materials are mixed at 1:100 and cured at a temperature of 120 ° C. The recommended curing time is 13-20 min.

Fifth, all tools and containers that come into contact with liquid silica gel should be kept clean and clean, and should not be in contact with phosphorus (P), nitrogen (N), sulfur (S) compounds and metalorganic materials to avoid product catalyst failure and non-vulcanization phenomenon.
