Henkel Alodine®871™Touch-n-Prep Coating Meets Demands of Aerospace and Defense Industries

Published on 2009-05-15. Author : SpecialChem

Henkel announces the development and approval of Alodine® 871™ Touch-n-Prep trivalent chromate-based touch-up coating to U.S. military specification MIL-DTL-81706B. The coating is used to repair bare areas of metal surfaces to prevent corrosion. The ready-to-use pen applicator provides an easy and safe application method by delivering the coating directly onto the surface. The unique Alodine® 871™ no-rinse conversion coating can be applied to most bare metal surfaces including aluminum, ferrous and galvanized substrates.

Henkel is committed to developing innovative and sustainable products that contribute to process efficiencies for our customers, said Patrice Buisson, global marketing director, Henkel aerospace. Alodine® 871™ is a great example of such a technology due to its no-rinse formula and easy-to-use pen applicator that controls the amount of product dispensed.

Alodine® 871™ inhibits corrosion by forming a barrier layer on the substrate preventing moisture from reaching the substrate and initiating the corrosion process. The coating also has low electrical resistance due to its metallic nature, and does not significantly restrain the flow of electrical current through the coating. In addition, it provides improved paint adhesion by depositing a clear to light blue iridescent film on application.

Touch-N-Prep® coating represents a dramatic environmental improvement over current methods of chemical film touch-up. The film itself only needs to be thoroughly dry in order to be effective for primer and top coat applications. Alodine® 871™ however does not require rinsing, and can be airdried or force-dried with hot air or an infrared lamp. This optimized application method greatly reduces the amount of chemical used and generates no secondary waste associated with other repair methods. The dry-in-place nature of the coating eliminates the need to contain and properly dispose of rinse water needed with traditional conversion coatings.

Alodine® 871™ is suitable to repair or touch-up non-chrome, trivalent chrome and traditional conversion coating areas. Additionally, it can be used to coat small parts where a conversion coating tank line is not practical. The coating is formulated for bare corrosion protection and for bonding applications when combined with organic coatings or structural adhesives.

In addition to the military specification approval, Alodine® 871™ Touch-N-Prep coating is also being evaluated by many of the leading aerospace and defense manufactures.
