Pentaerythritol is mainly used in the coatings industry, can be used to manufacture alkyd resin coating, can make the coating film hardness, luster and durability.It also USES up with anger paint, lacquer and printing ink of pine resin needed raw materials, coating and drying oil, smoldering sex and aviation lubricating oil and so on.
Also used in medicine, pesticide and so on production.Pentaerythritol molecules containing four hydroxymethyl equivalent, with high symmetry, so the production raw material is often used as multifunctional compound
By its nitrification can produce pentaerythritol tetranitrate (taian, PETN), is a kind of high explosives;Esterification available pentaerythritol three acrylate (PETA), used as a coating.
