Waterborne Coatings

RSS

Today’s coatings market expects more from its white pigments than brightness and opacity. White pigments, such as titanium dioxide (TiO2), barium sulfate (BaSO4) and zinc sulphide, are just examples of many ingredients possible in a complex coatings formulation.

The binders used in water-based paints are traditionally produced by emulsion polymerization.

Troysol™ Z372 is a high-performance universal mar and slip additive that improves the wetting of low-surface-energy and contaminated substrates, resulting in uniform film coverage.

Scottish scientists Dr. David Hepworth and Dr. Eric Whale invented Curran®, an innovative additive for coatings. Curran® was developed with a special, patented process by Scottish company CelluComp Ltd.

In this article, we evaluate how silicone additives can be used beyond the traditional benefits, and demonstrate how these additives can bring added performance in titanium dioxide-based formulations to prevent this age-old problem.

Worldwide, the popularity of wood decks continues to rise.

Emulsion polymerization is a useful technique for preparing waterborne latexes used in coatings and inks.

In general, the primary function of coatings is to help protect surfaces by forming a nonporous barrier that can alleviate chemical corrosion, mechanical abrasion, dirt pick up and other sources of damage.

With stringent environmental and health regulations, waterborne coatings are increasingly replacing solventborne paints.

Grit blasting of metal surfaces, a routine surface preparation technique prior to painting, is expensive, labor-intensive, time-consuming, and generates a large amount of hazardous, powdery waste
