Use instructions and precautions
1. 3301 The promoter is not included in the resin, and the appropriate amount of accelerator and curing agent must be added according to the operating environment and operational demand.
2. Be sure to use the water content of the material such as glass fibers, fillers, pigment paste, etc., pay attention to the compatibility of pigment paste and unsaturated polyester resin.
Storage conditions
1. The resin should be stored in a dry chamber below 25 ° C before use before the original packaging (avoiding the damage of the bucket and bucket).
2. Elevation of temperature and light irradiation will significantly reduce storage, and avoid direct sunlight and away from heat.
3. Unsaturated polyester resin liquid containing styrene is flammable, and it is far from the fire. Note See Secure Data Sheet.
