product properties
WL-4001 is a pre-promoted unsaturated polyester resin. The resin has the advantages of low viscosity, good infiltration of the glass fiber; low contraction, high toughness, and strong strength.
main application
The main molding process of WL-4001 resin is vacuum import, which is widely used in automotive components, cooling towers and other fields.

CIThization conditions: room temperature to curing for 24 hours, 40 ° C, 60 ° C, 80 ° C after curing
2 hours
Test conditions: temperature 23 ± 2 ℃, relative humidity 50 ± 6 %
Instructions and precautions
1. The WL-4001 resin has a promoter, and the curing agent can be used by MEKP, which should ensure that the curing agent is within the validity period. Usually, the MekP/CO curing system is not less than 15 ° C. When the temperature is low, the promoter can be added appropriately to adjust the reaction.
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.
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.
