This letter is to confirm that Highland International has reviewed and tested the use of Cleanwirx 207 when used with vapor blasting to achieve a recommended surface preparation. We found that adhesion values may be improved when using this product as directed. We found no loss of adhesion when applying Highland 475R Series Dry-Fall Epoxy, Highland 827 Series Multipolymeric Matrix, or Highland Chem-Temp 74 Series (3 coatings specifically tested) compared to samples applied to dry abrasive blasted substrates to achieve the same surface preparation.
Our findings allow us to support the use of Cleanwirx 207 with vapor blasting to achieve the recommended surface preparation prior to application of any Highland Coating. Highland does recommend that all standard inspection practices be employed to ensure all surface preparation standards are met including standards for soluble salts where specified.

IONYX Coatings has reviewed and tested the use of Cleanwirx 207 in conjunction with our coatings as well as adhesive fusion primer. Across all products, adhesion results were improved when surface preparation included Cleanwirx 207. According to independent third-party tests, adhesion results were improved by over 100% in some cases compared to the use of our products alone.
IONYX Coatings recommends the use of Cleanwirx 207 in conjunction with standard surface preparation to achieve the best possible results for our coatings, and any coating used in conjunction with our coatings or primer.

Based on the results obtained under the conditions tested, CleanWirx 207 is capable of reducing the levels of chlorides on the surface of steel to below the accepted industry standard when used properly. Additionally, Tnemec coating systems tested maintained acceptable adhesion to the steel panels prepared with the CleanWirx 207solution.
Tnemec’s literature will be updated to reflect these findings, and will be available for Tnemec sales representatives to support the use of CleanWirx 207 in abrasive and wet-abrasive practices for the removal of soluble salts from blasted steel.
