Product Description
WL-2020C is a general-purpose unsaturated polyester resin with high reactivity, low viscosity and low volatility. At the same time, the resin has the advantages of high transmittance and good toughness after curing.
Application
WL-2020C resin is suitable for hand lay-up, continuous board making and other production processes, mainly used for lighting tiles and machine-made boards

Instructions and attentions
1. WL-2020C resin contains 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, and pay attention to the compatibility of pigment paste with unsaturated polyester resin.
3. It has high reactivity, and the setting of its board speed should be determined in combination with the actual state of equipment conditions and process conditions. When selecting glass fiber, consider matching the refractive index of the resin to ensure the light transmittance of the board.
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.
