Application Data

This emulsion is compatible with most common additives, pigments and pigment preparations and can be combined with other emulsions. Due to the variety of products in the market, compatibility and storage stability have to be tested from case to case. Polyurethane thickeners are highly recommended but most commercial thickeners can be used. Due to the low minimum film forming temperature of this emulsion it is not mandatory to add coalescing agents. For application properties of the final product it might be helpful to add co-solvents like butyl glycol, butyl diglycol, Texanol or glycolether. For Storage and Safety information see Material Safety Data Sheet.
