Abstract
Disclosed is a process for reducing volatile organic compound emissions during the processing and coating of articles contaminated with water insoluble contaminants. The process prevents the formation of undesired etching and pitting which increases the surface area of an article. The use of volatile organic compound-containing surface coatings is thereby reduced resulting in reduced volatile organic compound emissions. The process of the present invention includes contacting a surface with a terpene finishing agent to remove water insoluble contaminants from such surface and applying an amount of volatile organic compound-containing coating to effectively cover the surface at a desired coating thickness.
Claims28
A method for reducing volatile organic compound emissions in the application to a surface of a VOC-containing coating, comprising:
- a) contacting said surface with an effective amount of a finishing agent having a pH of about 6.0 pH to about 9.0 pH comprising terpene to remove oils present on said surface;
- and
- b) applying to said contacted surface an amount of a VOC-containing coating effective to coat said surface, said VOC-containing coating including a compound selected from the group consisting of toluene, methylene chloride, isopropyl alcohol,
- butyl alcohol and mixtures thereof, said VOC-containing coating selected from the group consisting of inks, paints, plastic coatings and mixtures thereof.
A method for reducing volatile organic compound emissions, comprising treating a surface with an effective amount of a terpene finishing agent having a pH of about 6.0 pH to about 9.0 pH to reduce the amount of volatile organic compound-containing coatings-required to cover said surface.
A method for reducing volatile organic compound emissions in the manufacture of metal containers, said containers having interior and exterior surfaces, comprising:
- a) contacting an effective amount of a terpene finishing agent having a pH of about 6.0 pH to about 9.0 pH to substantially remove contaminants present on said metal containers, said containers having a surface roughness average of less than about 10.0 Ra after said contaminants are substantially removed;
- and
- b) applying said metal containers with an amount of a volatile organic compound-containing coating to effectively cover the interior of said containers, said amount of coating being less than about 165 mg per 16 oz. container.
A method for reducing volatile organic compound emissions comprising reducing the etching of a metal surface by treating said surface with a terpene finishing agent having a pH of about 6.0 pH to about 9.0 pH prior to coating said metal surface with a volatile organic compound-containing coating and coating said metal surface with an amount of said volatile organic compound-containing coating to effectively cover said metal surface.
