Instructions and attentions
1. WL-3301BC resin does not contain accelerators. When using, appropriate amounts of accelerators and curing agents must be added according to the operating environment and operating requirements.
2. When using, be sure to control the water content of materials such as glass fiber, filler, pigment paste, etc., and pay attention to the compatibility of pigment paste with 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.
