Abstract:
La presente invención proporciona un revestimiento y/o sistema de revestimiento a base de agua que se puede usar para formar revestimientos o capas húmedas resistentes al escurrimiento en una amplia variedad de sustratos. El sistema de revestimiento es particularmente eficaz para proteger sustratos que contienen metal, tales como los contenedores de carga intermodales, frente a la corrosión. Generalmente, la presente invención proporciona composiciones a base de agua adecuadas para formar capas de imprimación en sustratos. Preferentemente, el imprimador incorpora un nivel alto de uno o más agentes CAS para obtener una resistencia al escurrimiento óptima mientras se seca en un intervalo amplio de ambientes de humedad relativa. Alternativamente, se pueden hacer modificaciones para controlar la temperatura y humedad durante la aplicación por rociado y secado como forma para aumentar la resistencia al escurrimiento del revestimiento.
Abstract:
La presente invención proporciona un sistema de revestimiento a base de agua que se puede usar para formar un revestimiento durable, resistente a la abrasión, robusto y protector en una amplia variedad de sustratos. El sistema de revestimiento tiene, favorablemente, excelentes propiedades de adhesión y se puede aplicar directamente sobre superficies de acero inoxidable sin necesidad de una capa de imprimación intermedia. Sin embargo, si se desea, se pueden usar capas de imprimación u otros tipos de revestimientos en conjunto con el sistema de revestimiento de la presente invención. El sistema de revestimiento es particularmente eficaz para proteger sustratos que contienen metal, tales como contenedores de carga intermodales refrigerados. Los revestimientos resultantes son flexibles y resistentes al impacto. Al ser a base de agua, las composiciones de revestimiento tienen menos emisiones de COV y menos olor residual que las composiciones a base de solvente.
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.

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.

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. The coating system advantageously has excellent adhesion properties and can be directly coated onto stainless steel surfaces without requiring an intervening primer layer. Primer layers or other types of coatings can be used in combination with the coating system of the present invention if desired, however. The coating system is particularly effective for protecting metal-containing substrates such as intermodal, refrigerated cargo containers. The resultant coatings are flexible and impact resistant. Being water-based, the coating compositions have lower VOC emissions and less residual odor than solvent-based compositions.
