Instructions and precautions
1. WL-1911 resin does not contain a promotional agent. When used, add an appropriate amount of promotional agent and curing agent according to the operating environment and operating needs.
2. When using, be sure to control the water content of glass fiber, fillers, pigment paste and other materials, and pay attention to the compatibility of pigment paste and unsaturated polyester resin.
Storage conditions
1. The resin should be stored in a dry room below 25 ° C before using the resin before using the original packaging (avoid damage to the barrel and barrel).
2. The increase in temperature and light irradiation will significantly reduce the storage period. Direct sunlight and stay away from the thermal source should be avoided during storage.
3.. The unsaturated polyester resin liquid containing the styrene is flammable, and it should be far away from the bright fire when storing. Pay attention to the security data table.
