Abstract:
An electrocoating composition and a coating formed from the composition are described herein. The electrocoating composition includes at least an epoxy resin component, an isocyanate-functional component and a silica-based additive. The coating shows about 40 to 70% reduction in edge corrosion relative to a conventional coating.
Abstract:
A method of bonding two or more components of a free flowing powder composition is described herein. At least a first component, such as for example, a metal effect pigment, and at least a second component, such as for example, an organic material is provided, and one or both components are heated by variable frequency microwave radiation to bond or fuse the components together. Coating compositions and coated articles made by the described method are also provided.
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:
A silicone-modified polyester resin and methods for making the resin are described herein. The method includes production of a siliconized intermediate which is then esterified to give a silicone-modified polyester resin. Coating compositions including the silicone-modified polyester resin are provided, and coated articles with the coating composition applied to at least a portion of a surface thereof are also provided.
Abstract:
The present invention provides a water-based coating system that can be used to form a durable, abrasion resistant, tough, protective coating on a wide range of substrates, including the underbody of transport vehicles, storage units, and the like. The coating composition includes an asphaltic component and advantageously has excellent adhesion properties when coated onto metal surfaces, including the underbody of transport vehicles, storage units and the like. The coating system is particularly effective for protecting metal or metal-containing substrates forming the underbody of an intermodal cargo container. The resultant coatings are flexible and impact resistant.
Abstract:
A substrate may be coated with a various combinations of a water-dispersible polyisocyanate, a water-soluble acid or salt thereof, and/or an isocyanate-reactive compound. The resulting coated article has improved coating adhesion, especially near coated burnished surfaces such as sawn edges or grooves.
Abstract:
The present invention provides a water-based coating and/or coating system that can be used to form sag resistant wet layers or coatings 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 compositions suitable to form primer coats on substrates. Desirably, the primer incorporates a high level of one or more CAS agents for excellent sag resistance while drying in a broad range of relative humidity environments. Alternatively, modifications can be made to control temperature and humidity during spray application and drying as a way to increase sag resistance of the coating.
Abstract:
A coating system for application to metal components prior to assembly or fabrication into large metal objects is described. The system includes a composition comprising a water-dispersible polymer component, a crosslinking agent, and a conductive material. When applied to a metal substrate, the coating system is weldable and provides optimal corrosion resistance during fabrication or assembly.
Abstract:
This disclosure is directed to a self-crosslinkable polymer and and an aqueous dispersion comprising particles of the polymer. The self-crosslinkable polymer has a molecular skeleton containing urethane linkages, and a hydrazide functional group and a carbonyl functional group capable of reacting with the hydrazide functional group chemically bonded to the molecular skeleton.
