CTK 260

Neutral Multi-Metal Inhibitor, with enhanced brass passivation.

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 260 has been developed especially for this difficult and changing environment. It functions over a wide range of water qualities and hardness.
It benefits from enhanced passivation for copper, brass and bronze, and in addition provides protection for components made of most aluminium alloys, steel and iron. In certain conditions, the use of CTK 260 may extend the life of the hot cure tank.
