Instructions and precautions

1. 2031 The resin does not contain a promoter. When used, the appropriate amount of promoter and curing agent must be added according to the operating environment and operating needs.

2.  When using, you must pay attention to controlling the water content of glass fiber, filler, pigment paste and other materials, and pay attention to the compatibility of pigment paste and unsaturated polyester resin.

3..  Its reaction activity is high, and the setting of the board speed shall be determined in conjunction with the actual state of the equipment and process conditions. When choosing a glass fiber, consider matching the discount rate of the resin to ensure the light transmission of the plate.

Storage conditions

1.  The resin should be stored in a dry room below 25 ° C before using the resin before using the original packaging (avoid damage to the barrel and barrel).

2.  The increase in temperature and light irradiation will significantly reduce the storage period. Direct sunlight and stay away from the thermal source should be avoided during storage.

3..  The unsaturated polyester resin liquid containing the styrene is flammable, and it should be far away from the bright fire when storing. Pay attention to the security data table.
