Characteristics & description

YBS-7501 is a pultrusion molding resin with moderate viscosity. It has high reactivity, good heat resistance and excellent rigid strength. Good wettability with glass fiber. The products made have high mechanical strength. The resin is usually mixed with low profile additives for pultrusion process.

Product Application:

YBS-7501 unsaturated polyester resin can be widely used in doors and windows, pipes, tent pole, fishing rod and other products.

Storage & Use:

1、Before use, the resin should be in the original packaging (avoid breakage of the barrel and barrel),25℃ below the dry indoor storage period of three months. Keep the barrel sealed to prevent moisture from invading and tighten the lid.

2、The increase of temperature and light exposure will significantly shorten the storage period, storage should be away from heat sources and avoid direct sunlight.

3、Unsaturated polyester resin containing styrene is flammable and stored away from open fire.

4、If the resin is not used properly, it will cause injury. Avoid contact with skin and eyes. Wear necessary protective equipment and clothing. For product safety instructions, see Yibeisen's "resin safety instructions (MSDS)"
