Instructions and precautions
1. WL-5003 resin should choose the solid system according to factors such as the specific equipment, products, process temperature, and extrusion speed according to its specific equipment, products, process temperature, and extrusion speed. Generally recommended: BPO 0.5%~ 2.0%; TBPB 0.5 ~ 1.5%.
2. The volume contraction rate of unsaturated polyester resin is very large. When pulling the diameter rod material, it is recommended to carry out felt. When pulling the profile, it is recommended to use the low contraction additives provided by Wanglin New Materials such as 3814, 3892, etc., such as 3814, 3892, etc., and so on. Some low-contraction additives are not compatible with 503-1, and there will be layers in use, but this is normal, and it must be added when used.
3.. When using, you must pay attention to controlling the water content of glass fiber, filler, 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.
