The "Tri-CLPS 1000QC" is a trivalent chromium conversion coating treatment that achieves corrosion resistance equivalent to that of hexavalent chromium-containing conversion coatings on unpainted surfaces. While maintaining strong adhesion to the coating and stability in mass production, it adds the corrosion resistance of unpainted trivalent chromium. The management of the treatment bath is user-friendly, requiring no pH adjustment with a single-component replenishment. It is applicable to aluminum profiles and demonstrates performance that meets the painting standards for high-rise buildings. 【Features】 ■ Achieves unpainted corrosion resistance equivalent to hexavalent chromium-containing conversion coatings ■ AAMA2605 standard approval ■ Applicable to aluminum profiles ■ Unpainted corrosion resistance comparable to chromate coatings ■ Treatment bath management requires no pH adjustment with single-component replenishment *For more details, please refer to the PDF document or feel free to contact us.
