Vehicle Paint System With UV Protection
A vehicle paint system with UV protection for coating a base material and method of application to a vehicle component is disclosed. The vehicle paint system may include an anti-corrosion electro-deposition layer covering the base material; a basecoat with a UV stabilizer additive covering the electro-deposition layer, with the UV stabilizer additive including benzotriazole and a colored pigment that offsets a yellow color imparted by the benzotriazole; and a clearcoat covering the basecoat. This UV stabilizer additive may be in the clearcoat instead of or in addition to the basecoat.
1 . A vehicle paint system with UV protection for coating a base material of a vehicle component, the vehicle paint system comprising:
an anti-corrosion, electro-deposition layer covering the base material;
a basecoat having a UV stabilizer additive covering the electro-deposition layer, the UV stabilizer additive including benzotriazole and a colored pigment that offsets a yellow color imparted by the benzotriazole; and
a clearcoat covering the basecoat.
2 . The vehicle paint system of claim 1 wherein the colored pigment is a red shade of pigment.
3 . The vehicle paint system of claim 1 wherein the clearcoat has a UV stabilizer including the benzotriazole and the colored pigment that offsets the yellow color imparted by the benzotriazole.
4 . The vehicle paint system of claim 1 wherein the electro-deposition layer includes epoxy.
5 . A vehicle paint system with UV protection for coating a base material of a vehicle component, the vehicle paint system comprising:
an anti-corrosion, electro-deposition layer covering the base material;
a basecoat covering the electro-deposition layer; and
a clearcoat with a UV stabilizer covering the basecoat, the UV stabilizer including benzotriazole and a colored pigment that offsets a yellow color imparted by the benzotriazole.
6 . The vehicle paint system of claim 5 wherein the colored pigment is a red shade of pigment.
7 . The vehicle paint system of claim 6 wherein the electro-deposition layer includes epoxy.
8 . The vehicle paint system of claim 7 wherein the basecoat has a UV stabilizer including the benzotriazole and the colored pigment that offsets the yellow color imparted by the benzotriazole.
9 . A method of applying coatings to a base material of a vehicle component, the method comprising the steps of:
(a) applying an electro-deposition layer to the base material;
(b) applying a basecoat having a UV stabilizer additive to the electro-deposition layer, the UV stabilizer additive including benzotriazole and a colored pigment that offsets a yellow color imparted by the benzotriazole; and
(c) applying a clearcoat to the basecoat.
10 . The method of claim 9 wherein step (a) is further defined by applying an anti-corrosion pretreatment to the base material prior to applying the electro-deposition layer.
11 . The method of claim 10 wherein the anti-corrosion pre-treatment includes a phosphate.
12 . The method of claim 9 wherein step (a) is further defined by the electro-deposition layer being an epoxy-based electro-deposition material that is applied.
13 . The method of claim 9 wherein step (c) is further defined by the clearcoat including a UV stabilizer having the benzotriazole and a colored pigment that offsets a yellow color imparted by the benzotriazole.
14 . The method of claim 9 wherein step (b) is further defined by the colored pigment being a red shade of pigment.
