A final rinse for a phosphatized metal surface includes a phosphoric acid solution including aluminum chlorohydrate. The aluminum chlorohydrate solution is applied at a concentration of about 100 to about 1500 ppm at a pH of 3 to about 4.5. The pH is obtained by controlling the concentration of the phosphoric acid. This is preferably used to coat previously phosphatized metal surfaces such as iron, steel, aluminum and galvanize.

Aluminum based phosphate final rinse

Liquid additive for caustic soda cleaning solutions. Provides surfactants, foam control, and scale control; and good wetting and emulsifying properties for improved cleaning and ease of rinsing.

Controlled foam detergent additive

Liquid cleaning and bleaching concentrate which generates copious foam on dilution with water in a mechanical foam generator. Contains modified polyacrylic acid salt, sodium tripolyphosphate, sodium hydroxide, sodium silicate, sodium hypochlorite sodium alkane sulfonate, and (optionally) sodium polyacrylate.
