Paint and Coatings Additives

RSS

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.

 This study examined alternative routes for the production of butanol and propylene glycol. 

 Two new additives have been developed with patented applications for improving performance in solvent free, coatings. 

 A method to improve the hiding power of latex coatings by using a phosphate ester-based reactive surfactant and, thereby, reduce TiO2 usage is also discussed. 

 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. 

Traditional two-pack PUR technology combined with surface-modified nanosilica particles results in increased scratch and abrasion resistance in transparent, high-gloss coatings for plastics.

 The architectural design of a new amine epoxy hardener by molecular engineering has been shown to meet increasingly stringent market demands on legislation compliance, operator and environmental impact, and high productivity while showing excellent cost-performance balance of self-leveling epoxy systems. 

 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. 

New products are being developed to meet the challenge of delivering low- and zero-VOC offerings, including specialty resins, coalescents/plasticizers, water-based and energy curable colorants, foam control and silicone products.
