Time:2018-11-22 Views:2436
Silicone products can be seen everywhere in our lives, and the people are most afraid of the yellowing problem of silica gel products after a long time. How can we solve the yellowing problem of silica gel products?
Solution to yellowing of silicone products:
1. By adding curing agent with yellowing resistance.
2. Adopt high transparent high-quality silica gel raw material.
3. Control the mold temperature and curing time of silica gel products in the process.
In addition to the above methods, we can also use toothpaste, detergent and alcohol to clean and wipe the surface of silica gel to dry, so as to avoid the aging and yellowing of silica gel products accelerated by direct sunlight. In general, the yellowing phenomenon of transparent silicone products can only be alleviated, and can not be completely avoided.
