WL-4002C
Product Description
WL-4002C is a pre-accelerated general-purpose unsaturated polyester resin. The resin has the advantages of low viscosity, good glass fiber impregnation, low shrinkage, good toughness and high strength.
Application
WL-4002C resin is vacuum infusion, which is widely used in automotive parts, cooling towers and other fields.

Instructions and precautions for use
1. WL-4002C resin contains accelerator. When using it, an appropriate amount of accelerator and curing agent must be added according to the operating environment and operating needs.
2. When using, be sure to control the moisture content of materials such as glass fiber, fillers, and pigment pastes, and pay attention to the compatibility of the pigment paste and unsaturated polyester resin.
Storage conditions
1. Before use, the resin should be stored in the original packaging (to avoid opening and damaging the barrel) in a dry room below 25°C.
2. The increase in temperature and exposure to light will significantly shorten the storage period. Avoid direct sunlight and keep away from heat sources during storage.
3. Unsaturated polyester resin liquid containing styrene is flammable and should be stored away from open flames.Please refer to the safety data sheet.
