Test conditions: temperature 23 ± 2 ° C, relative humidity 50 ± 6%
Use instructions and precautions
1. The 3301B resin does not contain accelerator, and the appropriate amount of accelerator and curing agent must be added depending on the operating environment and operational demand.
2. Be sure to control the water content of the material such as glass fiber, filler, pigment paste, etc., pay attention to the compatibility of the pigment paste and the unsaturated polyester resin.
Storage conditions
1. The resin should be stored in a dry chamber below 25 ° C before use.
2. The increase in temperature and the light irradiation will significantly reduce the storage period, and the direct sunlight and away from the heat source should be avoided.
3. The unsaturated polyester resin liquid containing styrene is flammable, and it is far from the fire. Note See Secure Data Sheet.
