Kabasph Additive Solutions for Water-based Highly Concentrated Resin-free Colour Paste Systems

Water-based highly concentrated 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 aqueous carrier systems, settling and sagging during storage, flocculation and floating colour, foam generation that compromises paste quality, and consistency when let down into different waterborne coating or ink systems. Additives must be carefully selected to maintain compatibility with the aqueous carrier and final application system without adversely affecting colour strength, gloss, transparency, rheology, or storage stability.

l KBS-F0700 is a block acrylate dispersant for general-purpose water-based resin-free colour pastes. It provides broad compatibility and stable dispersion, making it suitable for a wide range of pigment concentrates and tinting systems.

l KBS-F0710 is a block acrylate dispersant for general-purpose water-based resin-free colour pastes. It offers reliable dispersion performance and is suitable for waterborne pigment concentrates requiring consistent colour development.

l KBS-F0720 is a block copolymer dispersant for high-concentration white pastes. It provides high water resistance and is suitable for inorganic pigment systems containing 20% matte powder. It is ideal for waterborne highly concentrated white and matte colour pastes.

l KBS-F0720A is a block acrylate dispersant for vapour phase aluminium oxide. It provides excellent viscosity reduction, making it suitable for highly concentrated colour pastes containing specialty aluminium oxide pigments or fillers.

l KBS-F2300 is an acid group-containing copolymer solution dispersant with alkali resistance. It is suitable for systems containing magnesium chloride or magnesium sulphate, providing stable dispersion in demanding waterborne colour paste formulations.

l KBS-F2400 is a modified polyurethane compound dispersant with alcohol ether resistance. It is suitable for water-based highly concentrated resin-free colour pastes using alcohol ether carriers or co-solvents.

l KBS-F2720 is a block copolymer dispersant for conductive graphite and acetylene black at 10% loading. It is also suitable for organic pigment colour pastes, providing stable dispersion and preventing floating and flooding in conductive waterborne systems.

l KBS-F270A is a block copolymer dispersant for 177/122/179 red pastes. It provides excellent colour development and stability for high-performance red pigment concentrates in waterborne resin-free systems.

l KBS-C420 is an organic polyurea anti-sinking thixotropic agent. It provides excellent anti-sinking and anti-sagging effects without affecting gloss and levelling, and has little effect on system viscosity. It is suitable for water-based highly concentrated resin-free colour pastes requiring rheology control and storage stability.

l KBS-X4140 is an alkyne glycol derivative defoamer. It effectively reduces dynamic surface tension and provides good foam inhibition and defoaming performance. It is suitable for water-based highly concentrated colour pastes where foam control is critical during dispersion, pumping, and application.

Application Areas

Water-based highly concentrated 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 Waterborne Coatings Tinting Systems — Used in architectural coatings, industrial coatings, and waterborne paint tinting systems where accurate colour matching and convenient let-down are essential.

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

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

l High-Concentration White and Matte Pastes — Used for high-concentration white pastes and matte colour pastes where water resistance, matte powder compatibility, and stable colour development are required.

l Conductive and Specialty Pigment Pastes — Suitable for conductive graphite, acetylene black, and specialty pigment pastes where stable dispersion and conductivity are important.

l Waterborne Adhesives and Sealants — Used in waterborne adhesives and sealants where colour pastes must be compatible with aqueous binder systems and maintain storage stability.

l General Waterborne Colourants — Suitable for a broad range of waterborne colourants where compatibility with different carrier systems and final binder systems is essential.
