block copolymer

• Especially improves the wet-adhesion of aqueous systems on critical substrates, such as e.g. old alkyd resin coatings.
• Also applies to substrates that cannot be sanded previously because accessibility is difficult.
• Has no influence on drying behavior and storage stability of the aqueous system.
• The properties like e. g. hardness, flexibility, gloss or tendency to yellowing of the dry film are not influenced when using it.

Used as an adhesion promoter for aqueous emulsion paints and alkyd emulsions applied on aged coatings.
