Abstract
A process for preparing aqueous coating agents with adjustable optical effects by mixing at least two storage-stable pre-mixed aqueous modules (units) is described, in which A) at least one aqueous special effect module containing one or more special effect pigments, one or more anionic and/or non-ionic stabilised water-dilutable binders, one or more organic solvents, at least 20 wt. % of water and optionally conventional lacquer additives, and B) at least one aqueous binder module containing one or more anionic and/or non-ionic stabilised water-dilutable binders, water, and optionally one or more organic solvents, one or more cross-linking agents and/or conventional lacquer additives, are mixed together.
Claims18
A process for preparing an adjustable optical effect aqueous coating agent comprising:
- selecting at least one storage-stable, premixed, aqueous, special effect module A and at least one storage-stable, premixed, aqueous, binder module B, and
- mixing at least modules A and B to form the coating agent, wherein
- the aqueous special effect module A comprises at least one special effect pigment, at least one anionic or non-ionic stabilized water-dilutable polyurethane binder or a combination or at least one anionic binder and at least one non-ionic binder, at least one organic solvent and at least 20 wt-% of water, and
- the binder module B comprises at least one anionic or non-ionic stabilized water-dilutable polyurethane binder or a combination of at least one anionic binder and at least one non-ionic binder and water.
