HYDROPALAT WE 3240 has the following advantages:

• Good substrate wetting in aqueous industrial, wood, automotive and exterior paints and coatings and printing inks
• Considerable reduction of interfacial tension
• Low foaming tendency
• Easily blended
• Often reduces dirt pick-up and improves graffiti removal

Compared with substrate wetting agents based on other chemicals, such as block copolymers (HYDROPALAT WE 3110, WE 3130), sulfosuccinates (HYDROPALAT WE 3475) or acetylene diol derivatives, HYDROPALAT WE 3240 brings about a much greater reduction in static interfacial tension. Even when it is present in a concentration of 0.5%, values much lower than 25 mN/m can be achieved. Dynamic interfacial tension is shown below as a function of frequency.

Application

HYDROPALAT WE 3240 reduces interfacial tension in aqueous paints, coatings and printing inks, thus clearly improving substrate wetting and flow. Craters and dents can also be reduced. HYDROPALAT WE 3240 is tolerated excellently, is low-foaming and thus does not generally cause foam problems or incompatibilities even in low-solvent system.
