Kabasph Additive Solutions for Solvent High Filler Low Viscosity Systems

Solvent-based high filler low viscosity systems are widely used in coatings, sealants, adhesives, and industrial applications 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, controlling viscosity to maintain workability and application properties, preventing settling and sagging during storage, avoiding flocculation and floating colour, maintaining gloss and appearance, and ensuring compatibility with the resin system without adversely affecting curing, adhesion, or final film properties. Additives must be carefully selected to deliver strong viscosity reduction, excellent dispersion stability, and broad compatibility with different fillers and pigments.

l KBS-F111 is an acid polyester compound dispersant designed for wetting inorganic pigment fillers. It provides strong viscosity reduction, making it suitable for high filler content systems where efficient wetting and dispersion are critical.

l KBS-T0200 is an acid polyester compound dispersant with 100% active ingredient. It is a strong viscosity reducing dispersant, especially suitable for solvent-free and polyether polyurethane systems. Its solvent-free nature makes it valuable for low-VOC and high-solids formulations.

l KBS-F4020 is a modified polyurethane compound dispersant. It inhibits floating colour and stabilises gloss, while providing general-purpose dispersion, inorganic viscosity reduction, and organic pigment dispersion. It is suitable for high filler systems requiring both colour stability and viscosity control.

l KBS-F9100A is an acid polyester compound dispersant developed for strong viscosity reduction in high filler systems. It shows good viscosity reduction effect for alumina, aluminium hydroxide, magnesium oxide, boron nitride, and other fillers, making it ideal for functional filler systems.

l KBS-F8600 is an acid polyester compound dispersant. It provides efficient viscosity reduction and excellent stability, with particularly good viscosity reduction for aluminium oxide and aluminium hydroxide. It is suitable for high filler loading systems where stable dispersion and low viscosity are required.

Application Areas

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

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

l Putties and Fillers — Suitable for solvent-based putties, fillers, and repair compounds where high filler content and low viscosity are essential for easy application and sanding.

l Sealants and Adhesives — Used in 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 Flooring Coatings — Applied in solvent-based flooring coatings where high filler content provides durability and thickness, while low viscosity ensures good levelling and workability.

l Heavy-Duty Anti-Corrosion Coatings — Used in heavy-duty anti-corrosion coatings for steel structures, pipelines, and marine applications where high filler loading and low viscosity are needed for thick-film application.

l Marine and Industrial Coatings — Suitable for marine coatings and industrial coatings where high filler content and stable viscosity are required for performance and cost efficiency.

l Thick-Film Systems — Used in thick-film systems where high filler loading and low viscosity allow for single-coat application and efficient production.
