Kabasph Additive Solutions for Water-based High Filler Viscosity Reduction Systems

Water-based high filler viscosity reduction systems are widely used in coatings, sealants, and adhesives where high filler loading is required to reduce cost, improve mechanical properties, or achieve specific functional characteristics. However, formulating with these systems presents unique challenges: achieving efficient wetting and dispersion of high filler content in aqueous media, controlling viscosity to maintain workability and application properties, preventing settling and hard caking during storage, avoiding flocculation and uneven colour development, maintaining foam control in high-solids formulations, and ensuring compatibility with the aqueous binder system without adversely affecting drying, adhesion, or final film properties. Additives must be carefully selected to deliver strong viscosity reduction, excellent dispersion stability, and effective foam control.

l KBS-F2100 is an acid-containing group copolymer solution dispersant designed for inorganic pigment and filler dispersion in water-based high filler systems. It provides excellent dispersion stability for titanium dioxide, ensuring uniform colour development and consistent opacity even at high filler loading. Its strong affinity for inorganic surfaces helps reduce viscosity and maintain workability in high-solids waterborne formulations.

l KBS-F2200 is an acid group-containing copolymer solution dispersant for inorganic pigmented filler dispersion. It delivers excellent dispersion stability for titanium dioxide, making it particularly suitable for high-filled waterborne coatings and primers where TiO₂ stability and low viscosity are critical. Its effective wetting and dispersion performance help prevent agglomeration and settling in demanding high filler systems.

l KBS-X4140 is an alkynediol derivative defoamer. It effectively reduces dynamic surface tension and provides good foam inhibition and defoaming performance. It is suitable for water-based high filler viscosity reduction systems where foam generation during dispersion, pumping, and application can compromise film quality and production efficiency. Its dynamic surface tension reduction also aids in substrate wetting and levelling.

Application Areas 

Water-based high filler viscosity reduction systems are widely used across industries where high filler loading, low viscosity, and reliable performance are required. Typical application areas include:

l High-Filled Waterborne Coatings — Used in high-filled waterborne coatings for architectural, industrial, and protective applications where filler loading is increased to reduce cost or improve mechanical properties while maintaining workability and low viscosity.

l Putties and Surfacers — Suitable for waterborne putties, fillers, and surfacers where high filler content and low viscosity are essential for easy application, sanding, and smooth surface formation.

l Primers and Base Coats — Applied in waterborne primers and base coats where high filler loading provides opacity, adhesion, and cost efficiency while low viscosity ensures good sprayability and levelling.

l Sealants and Adhesives — Used in waterborne sealants and adhesives where high filler loading is required for mechanical strength, rheology control, and cost reduction, while maintaining good extrusion and application properties.

l Thick-Film Systems — Suitable for waterborne thick-film systems where high filler content and low viscosity allow for single-coat application and efficient production.

l Industrial and Maintenance Coatings — Used in waterborne industrial and maintenance coatings where high filler loading and stable viscosity are required for performance and cost efficiency.

l General Waterborne Formulations — Suitable for a broad range of waterborne formulations where inorganic fillers and titanium dioxide are used at high loading levels and viscosity control is critical.
