Formulation Notes
Water-sheeting polymer additive for automatic and self-serve car wash final rinse stages.
Method: Dissolve PEG-400 in water. Add cationic emulsifier with stirring. Add nonionic surfactant and IPA. Add preservative. Use dilution: 1:100 to 1:200 in final rinse arch. Properties: pH 5.0–6.5, clear liquid. Cationic rinse aids deposit a monomolecular hydrophilic film on the paint surface that converts water droplets into a continuous sheet, eliminating bead formation and the water spots it causes . This “sheeting” action allows blow dryers to remove water more efficiently, reducing energy consumption in tunnel washes.
