Perstorp offers two diols – BEPD (Butyl Ethyl Propanediol) and Neo (Neopentyl Glycol) – to improve performance in unsaturated polyesters. Neo is used in specialty unsaturated polyesters for tanks, pipes and for gel coats, mainly to improve water and chemical resistance.  BEPD further improves hydrolytic stability, and outdoor durability. It is used, for example, as a top-of-the-line gel coating for marine applications and leisure craft.
