注：
1) Curing Conditions: Samples were cured at room temperature for 24 hours, followed by 2 hours each at 40°C, 60°C, 80°C, and 100°C.
2) Test Conditions: Temperature 23±2°C, Relative Humidity 50±6%
Precautions for use
⚫The resin contains accelerators. When using, an appropriate amount of curing agent must be added according to the operating environment and operating requirements to ensure sufficient curing.
⚫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.
⚫When used as an anti-corrosion lining, please carefully select according to the storage medium and the Kewell anti-corrosion manual.
Packaging and storage conditions
⚫Packaging and specifications: 20L iron drum; 200L iron drum; 1000L IBC drum; tank truck
⚫Storage period: 9 months (keep away from light and keep in a dry place at 25℃)
⚫Before use, the resin should be stored in its original packaging (to avoid opening the barrel and damaging the barrel) in a dry room below 25°C.
⚫Temperature changes and light exposure will significantly reduce the storage period. Store away from direct sunlight and heat sources.
⚫Unsaturated polyester resin containing styrene is flammable and should be stored away from open flames. Please refer to the safety data sheet.
