product properties

WL-1602 is an indifference unsaturated polyester resin with medium viscosity and has high response activity and good physical properties.

 

main application

WL-1602 resin is dedicated to SMC/BMC production process. Widely used in septic tanks, water tank boards and other fields. 1602 has a stable thickening performance. After adding low contraction such as 3814, and low outline additives, it can be made into a standard low shrinkage SMC/BMC.

Instructions and precautions

WL-1602 is usually used in conjunction with 3814 to produce low shrinking molds. Under normal circumstances, the ratio of 1602 and 3814 is 70:30, and it can also be adjusted according to the actual situation. According to the size requirements of the final product, 300ppm ~ 600PPM can be added to the formula (calculated based on the total amount of resin and low contraction additives).

 

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.
