International Interprime 160 Mordant Solution
International Interprime 160 is a phosphoric acid based mordant solution for treating galvanised steel.
Best Uses
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.
Application
All surfaces to be coated should be clean, dry and free from contamination. Prior to paint application all surfaces should be assessed and treated in accordance with ISO 8504:2000. Oil or grease should be removed in accordance with SSPC-SP1 solvent cleaning.
Galvanised Steel
Galvanised surfaces can be very variable. The preferred method of treatment for subsequent application of protective coatings systems is to sweep blast in order to provide a "physical key" to the substrate following degreasing and cleaning as described above. Alternatively, the substrate should be abraded to remove areas of passivated zinc products. The surface should be washed to remove any traces of soluble zinc salts and allowed to dry before application of Interprime 160.
Approvals
- Highways Agency Registered Approved - Item No. 155
Compatibility
Coatings systems. However, care should be taken with regard to the dimensions of the galvanised steel. Thin flexible substrates, for example, may not be suitable for overcoating with thick high performance systems as in many cases these have limited flexibility.
