Pentaerythritol

详情

Pentaerythritol is a tetrahydric neopentyl alcohol. It is an odourless white, crystalline, solid compound. It is non hygroscopic, practically non-volatile and stable in air. It is apparently non-toxic and non-violating to the skin. The Pentaerythritol is principally used in the surface coating industries. The medium and long oil length Alkyd resins prepared from Pentaerythritol, dibasic, acids and drying or semidrying oils or fatty acids are widely used in compositions that dry rapidly to form surface coatings with high gloss, excellent water and alkali resistance and good ageing characteristics. Pentaerythritol is an alcohol prepared by treating acetaldehyde with formaldehyde in an aqueous solution of calcium hydroxide; used in synthetic resins and in paints and varnishes..
