Abstract

The present invention relates to a paint color testing kit and method. More particularly, a test kit that duplicates and eliminates the spray process utilized for both color and strength control of paint products in a quality setting. Also provided is the ability to substantially duplicate the surface in which the paint is to be applied to a testing member of the kit and the painted surface to be evaluated or repaired.

Claims

1. A method of evaluating color, transmission and reflectance properties of a cured coating composition, to provide a color match with a painted substrate said method consisting of

(a) applying a coating to an application card having thereon a removable polymeric coated receiver sheet and said card having there through an aperture of between ½

to 1 inch in diameter, where said aperture is covered on one side by the polymeric coated receiver sheet,

wherein said coating is applied in the aperture from the side opposite the receiver sheet, having the removable polymeric coated receiver sheet in place, in a thickness sufficient to provide an opaque cured film,

(b) removing excess coating from the card to form a coating layer over the aperture,

(c) curing said coating to provide an opaque film,

(d) removing the polymeric coated receiver sheet to expose the cured film filling the aperture and

(e) visually evaluating the cured film unaided, or with a spectrophotometer to provide a color match to a painted substrate.

2. The method according to claim 1 wherein the paint is automotive paint.

6. The method of claim 1 wherein a refinish coating composition is matched to an existing coating on a painted substrate.

7. The method of claim 1 wherein the cured film is removed from the aperture and compared to a coated subsrtate for color matching.

3. A kit for color matching paint said kit comprising a card having thereon a polymeric coated receiver sheet and further comprising an aperture therein between ½

inch and 1 inch in diameter, and a spatula to remove excess paint from said receiver sheet.

4. The kit of claim 3 wherein the polymeric coating is selected from the group consisting of polyethylene, polypropylene, crosslinked polyurethane and tetrafluoroathylene fluorocarbon polymers.

5. The kit of claim 3 wherein the card further comprises a removable disk covering the aperture in the card and protecting the coated receiver sheet.
