New Generation Inorganic Pigment Dispersant: Additol XL 6577®

Additol XL 6577 is a mid-molecular weight next-generation dispersant for use in all solvent-based, high-solids, ultra-high-solids and 100% solids coating and ink systems. The high-efficiency anionic "mono-synapse" anchoring function is bound by a specialized polyester chain and creates inter-particle spacing that will provide high efficiency. The newly designed molecular structure is highly reactive and therefore Additol XL 6577 bonds rapidly to all inorganic surfaces; providing better anti-caking and anti-settling performance. Additol® XL 6577 Benefits Additol XL 6577 is the latest addition to Allnex's globally recognized pigment dispersant series. It was developed to be one of the most efficient dispersants on the market. • During the development process, numerous benchmark studies were conducted and it was found that Additol XL 6577 achieved the highest efficiency level when used to disperse inorganic pigments in solvent-based formulations and also enabled additional pigment loading for both direct grinding and production of pigment bases. • Additol XL 6577 enables optimized use of expensive pigments at the highest level. Additol® XL 6577 Comparison In a standard white 2K acrylic monocoat, when Additol XL 6577 is used, at constant spray viscosity versus systems created with different dispersants, it provides a 5% solids increase versus a standard equivalent and 2% versus a premium equivalent. Additol® XL 6577 Benefits in Pigment Bases • Opportunity to load more inorganic pigment into the formulation. • Ability to load more filler versus equivalent products with lower usage quantity. • Improved pigment mix stability against settling during storage. • Compatibility with all solvent-based, high-solids, ultra-high-solids and 100% solids liquid resin systems. • Possibility of use in automotive, industrial, M&PC or architectural applications. • Recommended dosage optimization on pigment (0.25-2.5%). Additol® XL 6577 Results • Stable, low VOC formulations with improved opacity. • High pigment loading. • High dispersion capacity, especially for TiO2 pigments. • Prevention of caking and settling. • Achievement of very high gloss values. • Color consistency. • Improved corrosion performance.
