## Abstract

Use of a wax-containing composition as a surface coating in order to improve the cleanability of the surfaces, whereby the composition comprises: alkyd resin as binding agent at a concentration in the range of 20-60% by weight, sulfonates at a concentration in the range of 10-30% by weight, a wax, in particular a micro-wax at a concentration in the range of 1-10% by weight, and aliphatic hydrocarbon-based solvent at a concentration in the range of 10-50% by weight.

## Claims

### Claim at position 1

1-13. (canceled)

### Claim 14

A method for improving the cleanability of a surface, the method comprising coating the surface with a wax-containing composition comprising:
alkyd resin as a binding agent at a concentration in the range of 20% to 60% by weight;
sulfonate at a concentration in the range of 10% to 30% by weight;
wax at a concentration in the range of 1% to 10% by weight; and
aliphatic hydrocarbon-based solvent at a concentration in the range of 10% to 50% by weight.

### Claim 15 (depends on 14)

The method according to claim 14 wherein the concentration of alkyd resin in the composition is between 35% and 50% by weight.

### Claim 16 (depends on 14)

The method according to claim 14 wherein the alkyd resin is a urethane oil.

### Claim 17 (depends on 14)

The method according to claim 14 wherein the concentration of sulfonate in the composition is between 15% and 25% by weight.

### Claim 18 (depends on 14)

The method according to claim 14 wherein the sulfonate contains organic calcium sulfonate.

### Claim 19 (depends on 14)

The method according to claim 14 wherein the concentration of solvent in the composition is between 20% and 30% by weight.

### Claim 20 (depends on 14)

The method according to claim 14 wherein the solvent is white spirit.

### Claim 21 (depends on 14)

The method according to claim 14 wherein the concentration of wax in the composition is between 2% and 6% by weight.

### Claim 22 (depends on 14)

The method according to claim 14 wherein the wax is a micro-wax having a melting range of 60° C. to 90° C., a paraffin wax having a solidification range of 50° C. to 90° C. and/or a polyethylene wax having a melting range of 95° C. to 135° C.

### Claim 23 (depends on 14)

The method according to claim 14 wherein the composition further comprises a drying agent for the alkyd resin at a concentration of less than 1% by weight.

### Claim 24 (depends on 23)

The method according to claim 23 wherein the drying agent is cobalt octoate.

### Claim 25 (depends on 14)

The method according to claim 14 wherein the surface coated with the composition is on a device used in paint finishing lines, enameling rooms or enameling stations.

### Claim 26 (depends on 14)

The method according to claim 14 wherein the surface coated with the composition is an internal wall of an exhaust air plant or duct.

### Claim 27 (depends on 14)

The method according to claim 14 wherein the surface coated with the composition is on a device used in forming processes for plastic materials.
