WL-5016C
Product Description
WL-5016C is an orthophthalic unsaturated polyester resin specially used for pultrusion, with high reactivity and good wettability.
Application
WL-5016C resin has high mechanical strength and toughness. It is mainly used to make tent poles, grilles, doors and windows, etc.

Instructions and attentions
1. WL-5016C resin used in the pultrusion process, the curing system should be selected according to its specific equipment, products, process temperature, pultrusion speed and other factors. Generally recommended: BPO 0.5%~2.0%; TBPB 0.5~1.5%.
2. The volume shrinkage rate of unsaturated polyester resin is very large. When pulling large diameter rods, it is recommended to wrap with felt; when pulling thick profiles, it is recommended to use low shrinkage additives such as 3814 and 3892 provided by Wanglin New Materials. Some low shrinkage additives are not compatible with WL-5016C, and there will be stratification when using, but this is a normal phenomenon. When using, be sure to add it immediately and stir it evenly.
3. 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.
