Hand-cream resistance of trim paints improved

Thursday, 31 May 2012

Lowering the oil-uptake of the polymeric binder can increase the hand-cream resistance of trim paints significantly, a new study shows.

Hand-cream resistance of indoor paints can be significantly improved by lowering the oil-uptake of the polymeric binder. This can be achieved with multi-stage polymer dispersions tailoring the glass-transition temperatures of the various stages and their hydrophilicity / hydrophobicity, a technical paper in the upcoming June issue of the European Coatings Journal shows.

Atomic Force Microscopy illustrates that a test mixture of hydrophobic fatty acids and oils may change the morphology of films after exposure. An optimised binder shows only marginal changes in morphology demonstrating the success of the approach.
