Abstract
The invention relates to a method for producing a fast drying two or multi-component waterborne coating on a surface of a substrate. The method comprises applying a first component comprising a binder and a second component, being separate from the first component prior to application, comprising an absorber, and compositions and/or formulations prepared therefrom.
Claims47
A method for preparing a fast drying multi-component waterborne coating on a surface of a substrate, the method comprising the sequential steps of:
- a) applying component A consisting essentially of at least one water insoluble absorber to the surface of the substrate;
- b) applying component B consisting essentially of a fast-drying binder composition to the surface of the substrate to which the water insoluble absorber has been applied;
- and
- c) allowing the multi-component waterbome coating to dry,
- wherein said absorber is selected from the group consisting of organic super absorbent polymers, ion-exchange resins, hollow sphere polymers, molecular sieves, talcs, inorganic absorbers, porous carbonaceous materials, non-porous carbonaceous materials, and mixtures thereof.
A method for preparing a fast drying multi-component waterborne coating on a surface of a substrate, the method comprising the sequential steps of:
- a) applying component C comprising a fast-drying binder composition to the surface of the substrate;
- b) applying component A consisting essentially of at least one water insoluble absorber and component B consisting essentially of a fast-drying binder composition simultaneously, or nearly simultaneously, to the surface of the substrate to which said component C has already been applied;
- and
- c) allowing the multi-component waterborne coating to dry;
- wherein said component B is different from said component C;
- and
- wherein said absorber is selected from the group consisting of organic super absorbent polymers, ion-exchange resins, hollow sphere polymers, molecular sieves, talcs, inorganic absorbers, porous carbonaceous materials, non-porous carbonaceous materials, and mixtures thereof.
A method for preparing a fast drying multi-component waterborne coating on a surface of a substrate, the method comprising the sequential steps of:
- a) applying component B consisting essentially of a fast-drying binder composition and glass beads to the surface of the substrate;
- b) applying component A consisting essentially of at least one water insoluble absorber to the surface of the substrate to which component B has been applied;
- and
- c) allowing the multi-component waterborne coating to dry,
- wherein said absorber is selected from the group consisting of organic super absorbent polymers, ion-exchange resins, hollow sphere polymers, molecular sieves, talcs, inorganic absorbers, porous carbonaceous materials, non-porous carbonaceous materials, and mixtures thereof.
