Calcium soap of oxidised wax
in solvent


Product description

Hypax 450-20-50 A3 is a calcium soap of Hypax 450 oxidate which is used to formulate products to meet the requirements of MIL-C-16173D-4 and related specifications for automotive cavity and underbody protection.

The product is also used as a water displacing preservative coating for crude oil drilling pipes exposed to severe
