Abstract

Compositions for cleaning and priming a surface comprising a solution of titanium acetylacetonate; alkanol having 1 to 4 carbon atoms; alkanol selected from methylethylkeytone, methylisobutylketone, acetone and their mixture; and water.

The compositions, which perform both cleaning and priming in a one-step operation, cure quickly allowing rapid painting.

Claims

1. A composition useful for cleaning and priming surfaces comprising a solution of:

(a) 0.1 to 10 weight percent titanium acetylacetonate,

(b) 20 to 50 weight percent of alkanol having 1 to 4 carbon atoms,

(c) 20 to 50 weight percent of alkanone selected from the group consisting of methylethylkeytone, methylisobutylketone, acetone, and mixtures thereof, and,

(d) 5 to 40 weight percent water.

2. The composition of claim 1 containing 0.5 to 3 weight percent (a), 25 to 45 weight percent (b), 25 to 40 weight percent (c), and 10 to 35 weight percent (d).

3. The composition of claim 2 wherein said alkanol is isopropanol.

4. The composition of claim 2 wherein said alkanone is methylethylketone.

5. The composition of claim 2 containing about 1 weight percent titanium acetylacetonate.

6. The composition of claim 2 wherein said alkanol is isopropanol and said alkanone is methylethylketone.

7. The composition of claim 6 wherein said weight percents of (a), (b), (c) and (d) are about 1, about 39, about 30, and about 30 respectively.

8. The composition of claim 7 further comprising 0.1 to 0.5 weight percent of a perfume.

9. An aerosol can containing about 30 to 50 parts by weight propellent and 100 parts by weight of the composition of claims 1 or 7.

10. A pad impregnated with the composition of claims 1 or 7.

11. A method of cleaning and priming a surface comprising rubbing said surface with the composition of claims 1 or 7.

12. The method of claim 11 wherein said surface comprises material selected from the group consisting of aluminum, fiberglass, or ceramic.

13. The method of claim 11 wherein said surface is an aircraft or an automobile.

14. The method of claim 12 further comprising coating the surface with a paint selected from the group consisting of polyurethane-based paint or oil-based paint.

15. A concentrate composition comprising:

(a) 1 to 50 percent titanium acetylacetonate,

(b) 20 to 50 percent alkanol having 1 to 4 carbon atoms,

(c) 20 to 50 percent alkanone selected from the group consisting of methylethylketone, methylisobutylketone, acetone or mixture thereof,

(d) 10 to 40 percent water.

16. A method for cleaning and priming a surface comprising the steps of (1) diluting the concentrate composition of claim 15 with a diluting solution comprising 20 to 50 percent alkanol having 1 to 4 carbon atoms, 20 to 50 percent alkanone selected from the group consisting of methylethylketone, methylisobutylketone, and acetone, and 20 to 50 percent water, so as to form a cleaning and priming solution having:

(a) 0.1 to 10 percent titanium acetylacetonate

(b) 20 to 50 percent alkanol

(c) 20 to 50 percent alkanone, and

(d) 5 to 40 percent water, and (2) rubbing a surface with said cleaning and priming solution.
