Bway Interior Paint Can Linings
The following provides a general overview of the main enamel systems that are used on the interior of round paint style containers.
This material is a gray pigmented epoxy. It is designed for latex emulsions having the optimum performance with products that have a stable pH and with a pH higher than 8.0. This material can be used on all container components. The majority of the latex market is packed with this enamel.
This material is non pigmented epoxy-phenolic. It is used with products that have strong solvents in which the resin system will react with the tin plate substrate. This enamel is primarily used in containers packed with aero space / air craft coatings. The gold enamel is used on all container components.
The organosol is a gray pigmented vinyl dispersion. It is formulated for aggressive water borne products in which the 1447 enamel does not provide adequate substrate protection. The organosol system requires the application of a size or base coat in order to adhere to the substrate. The film weight is approximately 40% heavier than the gray epoxy and being a vinyl withstands the rigors of the ring – plug forming process without microfracturing. The organosol is easily attacked by strong solvents such as methyl ethyl ketone. The use of the organosol enamel is limited to the inside of rings and plugs.
