Paint and Coating Resins & Polymers

RSS

This article describes a designed set of experiments that compared the coatings properties of two-component waterborne polyurethane coatings and two-component solventborne polyurethane coatings.

This article highlights pertinent current and future issues shaping the coatings industry.

 Smart coatings are an area of development and commercialization that promises to change the expectations of what can be accomplished with coatings. 

Part one of this article discusses the theory of optimizing applied hiding and new techniques used to characterize applied paint films to determine the influence of rheology on application.

 The unique hybrid chemistry of oxidizable phenolic-based urethanes combines the drying property of fast-drying oeloresinous vehicles, the chemical resistance of phenolics and the toughness of urethanes. 

 The carbon dioxide-based hardcoats developed in this project offer a unique balance of properties that make them viable alternatives to existing hardcoat technologies, in particular for substances such as thermoplastic polycarbonate. 

 For testing paints and coatings, rapid loss?on?drying methods prove to be more desirable than traditional testing methods. 

More companies are adding and/or expanding their portfolios with biobased waterborne alternatives that offer the formulator/end user another benefit without sacrificing performance.

 The use of the pigment encapsulating acrylic binder in exterior applications can not only decrease the amount of TiO2 at the same hiding level, bringing possible cost reduction, but can also help to improve exterior durability such as dirt pick up resistance, tint retention and efflorescence resistance. 

 VeoVa monomer enhances the performance of vinyl acetate- and acrylic-based latices, significantly upgrading key properties such as water and alkali resistance in both polymer systems.
