For a long time, the product industry is very cautious about the application of silicone inner mold release agent. This may have a lot to do with different views on how the product is understood and used
People tend to have the following misunderstandings about silicone internal mold release agent:
1. The influence of printed matter, easy to cause the increase of the number of printing resistance.
2. Prepare adhesive products for floor MATS, resulting in poor adhesion.
3. The appearance of the product is easy to produce bright spots on the surface.
4.Easy to cause frost.
Because of the above misleading people often miss the opportunity, because they are afraid to stop using, the poor performance of the silicone mold release agent will not work. In fact, long-term use of internal release agent will form a light synovial on the mold, the product is easy to release, especially for the difficult release of silica gel products. Good use of internal release agent to improve production efficiency is very helpful, but the time is not short, the experiment needs to have a reasonable period of comparison.
Reasonable use of silicone internal mold release agent to determine the details, should grasp the following elements:
one The choice of silicone raw materials do not covet cheap. (Cheap raw materials, even if they have no problems, can be unstable because of their short vacuuming and handling times.)
The choice of disulfide, only the right choice, the more stable the better (there are other substances of low purity, the faster the product is cooked the better, but the more stable the better).
3. Don't go overboard. (Due to insufficient sulfur content of the product, especially the selection of rapid vulcanization agent, the surface is very good, in fact, the vulcanization curve has not been completed, so will spit out frost, may not be the cause of the inner peeling.)
4. Use the right amount. (It is an auxiliary, not a primary, use of raw materials, auxiliary materials and processing techniques will reflect its value.)
