WL-5005

Product Properties:

WL-5005 is a universal unsaturated polyester resin with median viscosity and high-reactive activity, high-pull speed, and high-thermal deformation temperature.


Main Application:

WL-5005 resin is widely used in various glass fiber enhanced molding products.

The main molding process of WL-5005 resin is pulling, entangled, RTM, etc.

WL-5005 resin is suitable for profiles with high requirements for rigidity.

Instructions and precautions

1. The WL-5005 resin should choose the solid system according to factors such as the specific equipment, products, process temperature, and extrusion speed of the WL-5005 resin. Generally recommended: BPO 0.5%~ 2.0%; TBPB 0.5 ~ 1.5%.

2.  The volume contraction rate of unsaturated polyester resin is very large. When pulling the diameter rod material, it is recommended to carry out felt. When pulling the profile, it is recommended to use the low contraction additives provided by Wanglin New Materials such as 3814, 3892, etc., such as 3814, 3892, etc., and so on. Some low -contraction additives are not good enough with 505, and there will be layers when used, but this is normal. You must use it when used.

3..  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.
