Multi-staged polymers represent fairly new technology that involves a mixture of polymers with different Tg ranges, resulting in a mix of hard and soft segments.
A new generation of hybrid waterborne alkyd dispersions has been specifically designed and developed to provide the best protection on horizontal and some vertical wood surfaces.
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.
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.
