Usage
1.As an important fine chemical intermediate, it is regarded as the middle and high end product of pentaerythritol, which is mainly used in high-end coatings industry.
2.Production of polyether, polyester, polyurethane, high-grade alkyd resin and photosensitive resin film
3.Used in advanced aviation lubricating oil
4.Used as a stainless steel color plate, advanced granite spray maskwithstrong adhesive force, friction resistanceandageing resistance
Storage
It should be sealed and shaded to be stored in a dry, cool, well ventilated place.
