A unique compound based on a new self-matting PU dispersion (PUD) offers excellent physical and chemical performance. This PUD is optimized to meet the latest requirements for anti-soiling and coffee stain resistance for automotive interior finishes.
Moving to more environmentally benign monomers is essential for the continuation of a highly beneficial relationship with polymers. This shift creates an opportunity to simultaneously access new property profiles. New polyols synthesized using a high-purity isosorbide illustrate what is possible.
Learn how one company transforms reclaimed materials into highly valuable, non-toxic, sustainable, recyclable, and price-competitive binders for use in paints, coatings, adhesives, and flooring products.
Elastomeric roof coatings have been used for many years to extend the useful life of several types of roofing substrates. The roof coatings market has seen significant growth, driven by the “cool roof” movement. This article describes the use of very hydrophobic highly branched vinyl esters for high-performance binders for elastomeric coatings.
Polyvinylidene fluoride (PVDF)-based topcoats have long been the choice of architects and specifiers who are seeking superior weatherability.Arkema, Inc. has developed water-based PVDF-acrylic hybrid dispersions to meet the need of resins applied in the field or over temperature-sensitive substrates.
This article discusses relating the colloidal stability of latexes to the ionic strength of the aqueous phase via the “critical coagulation concentration.
This technology showed a large effect on the dirt-pickup resistance, even at Tgs as low as -26 °C, requiring no formulation modification compared to an unmodified formula.
Salt ions affect the thickness of the "double layer" around the particles. As the double layer shrinks, the latex particles can move around more easily, and the result is a lower viscosity latex.
One of the most popular high-solids, low-VOC coatings is an epoxy coating. Epoxy coatings are resistant to most chemicals and corrosives, exhibit great adhesion, and have very low porosity. And they're extremely environmentally friendly; because they contain no solvents, they emit virtually no VOCs.
Polyester-based adhesion promoters (PEAPs) are a series of modified UP resins that can partially replace the main binders in coatings formulations to improve their adhesion to difficult substrates.
