Final seals improve the corrosion resistance and adhesion of the conversion coated metal surfaces that are subsequently coated with conventional, electrocoat and powder coatings.
Gardolene D 6800/6 is a liquid, acidic, chrome-free, reactive final seal for iron phosphate, ferroxphate and zinc phosphate conversion coatings, applied by spray or immersion. Gardolene D 6800/6 improves the corrosion resistance and adhesion of the conversion coated metal surfaces that are subsequently coated with conventional, electrocoat and powder coatings. A final DI or good quality RO water rinse is required after Gardolene D 6800/6.
Gardolene D 6871 is a non-chrome final rinse for conversion coated metal surfaces. Gardolene D 6871 is added to the last water rinse of the pretreatment process. Gardolene D 6871 reacts with the conversion coated metal surface to enhance paint adhesion and corrosion resistance.
A liquid non-chrome sealer that improves the corrosion resistance and paint adhesion of phosphated metal. The formulation contains no chromium or other heavy metals. Depending on process conditions, PhosGard 800HP can provide performance comparable to chrome sealers. PhosGard 800HP is used in spray or immersion washers in the sealer/rinse stage. PhosGard 800HP is applied to metals that have been iron or zinc phosphated.
