Typical areas of application include building structures, agricultural machinery, steel fences, outdoor public areas and steel components present in coastal environments.
APPLICATION
Pretreatment
The overall quality of the coating system is largely dependent on the type and quality of surface preparation, pretreatment.  Recommended type of surface preparation is grit blasting which must be performed.  Grit blasted surfaces are suitable to provide a moderate level of protection.
For galvanized steel sweep blasting is recommended.
 
Chemical pretreatment
Available methods of pretreatment include zinc and iron phosphating and chromating of galvanized steel. Recommended types of pretreatment depend on specific design requirements and on the need for corrosion resistance.
