Zingatarfree (Formally PU Tarfree MIO) is a very under-stated single-component polyurethane. It has been used with great success directly over Zinga on narrow-boat hulls, tug-boats, on the base of electricity pylons-legs (to keep out both local ground-water and also stray-currents from nearby electrified railway tracks) and also on brand-new truck chassis. It has extremely high resistance to salts (especially chlorides) and water penetration.

Zingatarfree is available in 1 Litre and 4 Litre tins and cures to a matt black finish
