Instructions and precautions
1. WL-5940 resin should choose the solid system according to factors such as the specific equipment, products, process temperature, and extrusion speed when the crowded process. Generally recommended: BPO 0.5%~ 2.0%; TBPB 0.5 ~ 1.5%.
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. Before using, the resin should be stored in the original packaging (avoid the damage of the barrel and the barrel) in a dry room below 25 ° C.
2. The increase in temperature and light irradiation will significantly reduce the storage period. Direct sunlight and stay away from the heat source should be avoided during storage.
3. The unsaturated polyester resin liquid containing the styrene is flammable, and it should be stayed away from Minghuo when storing. Pay attention to the security data table.
