Test conditions: temperature 23±2℃, Relative humidity 50±6%
Instructions and attentions
1. WL-8301C resin does not contain an accelerator, and an appropriate amount of accelerator and curing agent must be added according to the operating environment and operating requirements.
2. When using, be sure to control the water content of fillers, pigment paste and other materials, and pay attention to the compatibility of 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.
