International Interprime 160 Mordant Solution is a phosphoric acid based mordant solution for treating galvanised steel.

For the chemical pretreatment of galvanised steel prior to the application of protective coating systems, in order to ensure good adhesion where blasting or abrasion is not possible.

Coverage

20m² per litre

Application

Brush

This material is a one component coating and should always be mixed thoroughly with a power agitator before application.

This product contains phosphoric acid. Before commencing application reference should be made to the material safety data sheet (MSDS), and the appropriate personal protective equipment should be worn, e.g. gloves, goggles, face-mask etc.

Over-application will produce a dense black powdery layer which is not suitable for the application of subsequent topcoats. This will require either abrading or washing with fresh water to remove excess acid or powdery deposits, otherwise blistering and/or adhesion loss of topcoats can occur.

Thinning is not normally required. However, if application trials result in a dense black powdery surface, then Interprime 160 should be diluted with clean, potable water and further application trials undertaken.

It should be noted that in all circumstances galvanised steelwork is likely to require a similar coating thickness for adequate protection as might be needed on steel substrates. Application of thin films can result in penetration of this paint film by zinc salts in wet corrosive environments.
