Product Description
WL-5960 is a high-strength modified resin with medium viscosity and has high reactive activity, high-heat deformation temperature and good corrosion resistance.
Application
WL-5960 resin is mainly used in photovoltaic components, such as photovoltaic brackets and photovoltaic border. The main molding process is crowded. It is suitable for photovoltaic components under the requirements of high mechanical strength, high corrosion performance, high heat resistance and other environmental requirements.

Instructions and precautions
1. WL-5960 resin uses the solid system according to its specific equipment, products, process temperature, and extrusion speed when the crowded process is used to choose the solid system. Generally recommended: BPO 0.5%~ 2.0%; TBPB 0.5 ~ 1.5%.
2. The volume shrinkage rate of unsaturated polyester resin is very large. When pulling diameter rod material, it is recommended to make felt; when stretching the profile Wait, some low-contraction additives and WL-5960 are not compatible enough, and there will be layers in use, but this is normal, and it must be added when used.
3. 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.
