A new pigment dispersant and two new superwetting surfactants have been launched by Air Products, a provider of atmospheric, process and specialty gases, for use in the coatings industry. The company has specifically designed these new alkylphenol ethoxylate (APE) free surfactants in order to offer enhanced and superior performance.
The company engineered both Dynol 800 and 810 surfactants in order to remove defects found on difficult-to-coat substrates. These surfactants can provide higher performance, when compared to fluorosurfactants and silicones, together with the ecological advantages of zero solvents, APEs, HAPs and VOCs.
Primarily, performance in plastic and wood coatings is enhanced using Dynol 800 surfactant, whereas excellent performance in overprint varnishes and printing inks is enabled by Dynol 810 surfactant. These two products can be formulated and handled easily, reduce premium surface tension, while assisting foam control.
The company developed Zetasperse 3600 dispersing additive for extensive use across typical carbon black and organic pigments. This additive together with globally sourced grades of pigments has revealed strong performance. It can offer excellent pigment stabilization and dispersion, and be utilized in aqueous architectural coatings, inks and colorants, as grind aid. Zetasperse 3600 additive is cost-efficient dispersant specifically designed to reduce formulations, while decreasing the demands of manufacturers for optimizing complex formulation.
