Abstract
A solvent, organic acid and controlled water content mixture for wiping tnium and stainless steel surfaces just prior to painting. The mixture contains xylene, galacial acetic acid, alcohol, (selected from 2-propanol, n-propanol, methanol or ethanol), water, methyl orange and a paint thinner (selected from methyl ethyl ketone, toluene, methyl isobutyl ketone, ethyl acetate or other conventional lacquer-type solvents).
Claims1
A material for upgrading the adhesion ability of titanium and stainless steel surfaces to accept an organic coating comprising:
- 0.005-0.01 wt % of methyl orange;
- 0.5-1.0 vol. % of alcohol selected from the group consisting of 2-propanol, n-propanol, methanol and ethanol (containing less than 1% by wt. water);
- 0.5-1.0 vol. % of xylene;
- 0.5-1.0 vol. % of galacial acetic acid;
- 0. 02-0.10 vol. % of water;
- and,
- balance of volume to reach 100% of paint thinner selected from the group consisting of methyl ethyl ketone, toluene, methyl isobutyl ketone, ethyl acetate and lacquer type solvents.
