Acid Rinse Aid 93 is a buffered additive with wetting agents to lower the pH of the final rinse after phosphating and reduce the water’s surface tension. It works in both hard and soft water, and helps control streaking and staining. It also provides short-term corrosion protection for in-plant storage prior to subsequent coating, and improves the coating’s adhesion. Since it contains no chromates, waste treatment is simplified.
Concentration 0.5 - 2% by volume
Time 15 to 30 seconds
Temperature Ambient – higher temperatures will aid in drying.
Control pH of the final rinse should be maintained around 4 - 5
