Kabasph Additive Solutions for Resin-Free Colour Paste Systems

Resin-free colour paste systems are widely used in coatings, inks, and tinting applications where high pigment loading, strong colour strength, convenient let-down, and reliable final performance are essential. However, formulating with these systems presents unique challenges: pigment dispersion stability without a resin binder, viscosity control at high pigment loading, compatibility with carrier solvents, settling and sagging during storage, flocculation and floating colour, foam generation that compromises paste quality, and consistency when let down into different coating or ink systems. Additives must be carefully selected to maintain compatibility with the carrier solvent and final application system without adversely affecting colour strength, gloss, transparency, rheology, or storage stability.

l KBS-F0400 is a modified polyester polymer dispersant for general-purpose resin-free colour pastes. It provides excellent stability and is universal for organic pigments, inorganic pigments, and carbon black.

l KBS-F0420 is a modified polyester polymer dispersant designed for resin-free colour pastes using dibutyl ester, saturated aliphatic hydrocarbons, olefins, and other lower level solvents as carriers. It is degradable and suitable for solvent systems requiring environmental consideration.

l KBS-F0430 is a modified polyester polymer dispersant for non-resin colour pastes using dibutyl ester, saturated aliphatic hydrocarbons, olefins, and other lower level solvents as carriers. It is degradable and provides stable dispersion in resin-free systems.

l KBS-F8500 is a block copolymer dispersant for resin-free colour pastes using alcohol ether solvents, ether ester solvents, and acrylic monomers as carriers. It is particularly suitable for organic pigment dispersion.

l KBS-F8600 is an acid polyester compound dispersant for resin-free dispersions based on alcohol ether solvents, ether ester solvents, and acrylic monomers. It is particularly suitable for inorganic pigment dispersion.

l KBS-F1820 is a modified polyester polymer dispersant for general-purpose resin-free dispersions in medium-polar solvent systems. It is also suitable for micro-resin systems and provides good stability.

l KBS-C410 is an organic polyurea anti-sinking thixotropic agent for medium polarity solvent systems. It provides rheology control and prevents settling in resin-free colour pastes.

l KBS-C420 is an organic polyurea anti-sinking thixotropic agent for highly polar solvent systems. It provides effective anti-settling performance and storage stability in demanding resin-free colour paste formulations.

l KBS-X055 is a polyacrylate defoamer for medium-high polarity solvent systems. It provides foam inhibition and is suitable for resin-free colour pastes where foam control is required without compromising paste quality.

Application Areas 

Resin-free colour paste systems are widely used across industries where high pigment loading, flexible let-down, and reliable colour performance are required. Typical application areas include:

l Coatings Tinting Systems — Resin-free colour pastes are widely used in architectural coatings, industrial coatings, and automotive refinish tinting systems where accurate colour matching and convenient let-down are essential.

l Inks and Printing — Used in solvent-based ink colour pastes for flexographic, gravure, screen, and other printing applications where pigment dispersion, colour strength, and stability are critical.

l Pigment Concentrates — Suitable for high-concentration pigment pastes used in coatings, inks, and colourants, where dispersion stability and viscosity control are important.

l Industrial Coatings — Used for tinting industrial coatings, including protective coatings, machinery coatings, and general industrial finishes.

l Wood and Plastic Coatings — Applied in wood and plastic coating systems where resin-free colour pastes provide flexible colour adjustment and stable let-down.

l Automotive Refinish — Used in automotive refinish tinting systems where precise colour matching and consistent final appearance are required.

l General Solvent-Based Colourants — Suitable for a broad range of solvent-based colourants where compatibility with different carrier solvents and final binder systems is essential.

Formulating with resin-free colour paste systems requires additives that address dispersion stability, viscosity reduction, rheology control, anti-settling performance, and foam management—all while maintaining compatibility with the carrier solvent and final application system. Our comprehensive additive portfolio provides formulators with a complete toolkit for optimizing resin-free colour paste formulations. From KBS-F0400, KBS-F0420, KBS-F0430, KBS-F8500, KBS-F8600, and KBS-F1820 dispersants that ensure pigment stability with effective viscosity reduction, to KBS-C410 and KBS-C420 anti-settling thixotropic agents that prevent settling and improve storage stability, to KBS-X055 defoamer that controls foam in medium-high polarity solvent systems—every product is engineered for consistent performance, regulatory compliance, and cost-effective formulation.
