Abstract
There is disclosed a composition for forming a protective coating upon a substrate. The composition has been found particularly useful for forming a protective coating upon components of automotive vehicles, such as a bedliner for a pick-up truck. The composition may include, without limitation, an isocyanate component and an amine component and optionally includes one or more of a catalyst, stabilizer, pigment, fire retardant or other additives.
Claims20
A process for coating a surface of an automotive vehicle, comprising:
- a) providing a surface of an automotive vehicle;
- b) contacting the surface with a composition comprising:
- i) an isocyanate in an amount up to about 75% by volume of the composition, the isocyanate being at least 75% aliphatic by weight;
- and
- ii) an amine in an amount up to about 75% by volume of the composition.
A process for coating a surface of an automotive vehicle with a composition, comprising:
- a) providing a painted surface of a truck bed;
- b) providing at a temperature of no greater than about 90° C. an isocyanate component in an amount up to about 75% by volume of the composition, the isocyanate component being at least 75% aliphatic by weight;
- c) providing at a temperature of no greater than about 90° C. an amine component in an amount up to about 75% by volume of the composition;
- d) intermixing the isocyanate component and the amine component to form an admixture of the components;
- e) spraying the admixture onto the truck bed;
- and
- f) curing the admixture at about room temperature.

- c) providing at a temperature of no greater than about 90° C. an amine component in an amount up to about 75% by volume of the composition, the amine component being at least partially an aspartic ester of polyoxyalkyleneamine having a mole ratio of amine functionality to the ester of no more than 1:1;
- d) providing an effective amount of a metal salt for controlling static;
- e) providing a thixotropic agent;
- f) intermixing the isocyanate component and the amine component, the metal salt and the thixotropic agent to form an admixture of the components wherein the admixture is substantially free of any catalysts;
- g) spraying the admixture onto the truck bed;
- and
- h) curing the admixture at about room temperature.
