PAINT DETACKIFIER COMPRISING DICYANDIAMIDE/FORMALDEHYDE POLYMER AND A MULTIVALENT METAL SALT IN AN AQUEOUS SOLUTION; METHOD OF TREATING PAINT OVERSPRAY

摘要

A paint detackification treatment for paint spray booths include a water soluble polymer which is a dicyanadiamide formaldehyde condensation product in combination with a multivalent metal salt, preferably aluminum chlorohydrate. The composition is added to the overspray collection tanks and acts to detackify particles of paint which are collected in a water curtain. The combination of the dicyanadiamide formaldehyde and aluminum chlorohydrate permits a lower concentration of polymer to be used and also permits this detackification product to be used with a wide variety of aqueous and oil based paints.
