CTK 250

Neutral Multi-Metal Inhibitor

For use in the wash, rinse and hot water cure tanks of impregnation systems using Methacrylate based Porosity Sealants

An Impregnation system which uses Methacrylate based Porosity sealants and hot water curing can sometimes provide the customer with varying performance when it comes to the protection of the castings being processed. CTK 250 has been developed especially for this difficult and changing environment. It will over a  wide range of water qualities and hardness and will also provide protection for components made of most aluminium alloys, steel, iron, brass and bronze etc. In certain conditions, the use of CTK 250 may extend the life of the hot cure tank.
