Commonly used in the coating industry, it is a raw material for alkyd coatings, which can improve the hardness, gloss, and durability of coating films. It is also used as a raw material for modified rosin alcohol required for varnish, color paint, and printing ink, and can be used to produce flame retardant coatings, drying oils, and aviation lubricants. Pentaerythritol tetranitrate, made from pentaerythritol as raw material, is a highly explosive explosive. Pentaerythritol fatty acid esters can be used as plasticizers and stabilizers for polyvinyl chloride resins. In addition, it can also be used in the manufacturing of pharmaceuticals, surfactants, adhesives, pesticides, and lubricants.
