Abstract: Disclosed are Bisphenol A (BPA), Bisphenol F, Bisphenol A diglycidyl ether (BADGE), and Bisphenol F diglycidyl ether (BFDGE)-free coating compositions for metal substrates including an under-coat composition containing a polyester (co)polymer, and an under-coat cross-linker; and an over-coat composition containing a poly(vinyl chloride) (co)polymer dispersed in a substantially nonaqueous carrier liquid, an over-coat cross-linker, and a functional (meth)acrylic (co)polymer. Also provided is a method of coating a metal substrate using the BPA, BPF, BADGE and BFDGE-free coating system to produce a hardened protective coating useful in fabricating metal storage containers. The coated substrate is particularly useful in fabricating multi-part foodstuffs storage containers with “easy-open” end closures.

Abstract: A fast drying, heavy metal-free, high performance coating composition with outstanding UV resistance, and excellent corrosion resistance coupled with fast dry and long pot life. This coating can be applied over DTM, such as blasted cold rolled steel, or treated cold rolled steel, aluminum and treated aluminum. High corrosion resistance without sacrificing gloss or UV resistance achieved by selecting proper pigments and proper pigment design and packing by advantageously utilizing differing pigment morphologies (sizes and shape).

Abstract: A novel linear polyester resin is made by condensation of one or more aliphatic or cycloaliphatic polyols with one or more aliphatic or cycloaliphatic polyfunctional acids derived from biobased materials or a biological feedstock. Coating compositions and coated substrates using the novel linear polyester resin are also described.
Abstract: Polycyclocarbonate compounds and upgraded molecular weight polymers made from such compounds are provided. The polymers have particular utility in coating compositions, especially for use on food and beverage contact substrates that are formed into or will be formed into containers or container components.

Abstract: The present invention provides a water-based coating system that can be used to form durable, abrasion resistant, corrosion resistant, protective barriers on a wide range of substrates. The coating system is particularly effective for protecting metal-containing substrates, such as intermodal cargo containers, against corrosion. As an overview, the present invention provides water-based primer compositions suitable to form primer coats and topcoats on substrates. Desirably, the primer incorporates one or more chlorinated resins for excellent corrosion protection. These polymers not only provide excellent corrosion protection and but also show excellent adhesion to a wide range of substrate materials. The system also includes topcoat compositions enhance compatibility and adhesion to the primer and to provide enhanced application.
