What is the cause of resin aging? In fact, unsuitable temperature, application of pressure, ultraviolet rays, etc. will make the resin aging.
In order to prevent the aging of unsaturated polyester resin, it is recommended:
1. Try not to expose unsaturated polyester resin to sunlight for a long time. Sunlight has ultraviolet rays, which break the covalent bonds of resin molecules, and impurities can easily make the resin aging.
2. Don't apply pressure, try to put the resin in the space, and don't let the resin receive pressure.
3. The temperature is kept within the range of the resin material.
4. Do not let the resin come into contact with chemical substances. Some chemicals will dissolve the resin, such as acid-base salts will corrode the resin.
