RoHS COMPLIANT “NON-CHROMATE” CONVERSION COATINGS FOR ALUMINUM

ACCU-LABS 628-DM conversion coating process is available as a chromium free alternative for corrosion protection for aluminum substrates. The 628-DM coating provides a beautiful golden color with excellent corrosion resistance. Parts treated with 628-DM conversion coating process have consistently achieved 168 hours of salt spray protection per ASTM B-117. The coating is abrasion resistant and lends itself to good paint adhesion. ACCU-LABS 628-DM conversion coating process was developed to meet and exceed current RoHS standards, with the intention that all chromium compounds may eventually be banned. ACCU-LABS 628-DM development team was led by Robert Burnson. Bob brings with him over 50 years of hands on formulating experience. Bob was one of the early pioneers in environmentally green chemistry, especially in the areas of non-cyanide alternative chemistries and trivalent conversion films.
