Pigment Dispersion II, Testing

Ink in water isolated on white background. Rainbow of colors
Pigment dispersion quality in pastes and paints may be tested by one of several different techniques. Probably the most common method in labs and plants is taking readings with a grind gauge, usually the Hegman type (ASTM D1210). The main reason for doing this for pastes usually is to see whether the dispersion process has reached the required end point...

Taking Direct-to-Metal Coatings to the Next Level

Abstract colorful grid background
Direct-to-metal (DTM) coatings are designed to provide the performance of traditional primer–topcoat systems, but in one coat. As technologies for the development of DTM coatings have advanced and led to more desirable properties during application and in applied films, demand for these coatings has been increasing. As a result, while DTM coatings today still account for a small percentage of...

Highly Versatile Aluminum Flake for Water, Solvent and Ultra-low VOC Coatings and Inks

Highly Versatile Aluminum Flake for Water, Solvent and Ultra-low VOC Coatings and Inks
Liquid coatings and inks are facing increased pressure with respect to the presence of volatile organic compounds (VOCs). As a result, ink and coating formulators have to balance safety, regulatory, and emission standards while meeting their customers’ performance requirements. For low-VOC, metallic formulations, aluminum pigments are used to impart a desirable silver or metallic effect with excellent hiding power. In...
