Pale yellow granular solid powderбренд :
KabasphKabasph® KBS-24000 is a solvent-free, 100% active polymeric dispersant free of inert diluents. When dissolved in organic carriers, it rapidly wets pigments during grinding, cutting mill base viscosity, refining pigment particle size and lifting milling efficiency. This product facilitates high pigment loading for high-solid formulations, greatly improving color development, tinting strength, film transparency, surface gloss and black jetness. Its bio-based raw material composition offers eco-friendly advantages. Furthermore, it effectively suppresses pigment flocculation to maintain outstanding dispersion performance and long-term stability for finished coatings and inks. KBS-24000 is comparable to Solsperse 24000 in terms of performance and dispersing efficiency.

Product Advantages
l Solvent-free, 100% active – no inert diluents; flexible for organic carrier systems.
l Bio-based composition – supports eco-friendly, low-VOC formulations.
l Rapid pigment wetting and deagglomeration – refines pigment particle size, lowers mill base viscosity and boosts sand milling or bead milling efficiency.
l Excellent anti-flocculation performance – adsorbs onto pigment surfaces to form a steric hindrance barrier in organic solvent systems, inhibiting pigment flocculation, coarsening and sedimentation.
l Long-term storage stability – maintains outstanding dispersion performance in finished coatings and inks.
l Superior color development – fully unlocks pigments’ inherent color to improve tinting strength, film transparency, surface gloss and black jetness.
l High pigment carrying capacity – allows high pigment loading for high-solid formulas with less solvent usage.
l Broad compatibility – can be dissolved in diverse organic carriers for industrial coatings, printing inks, colorants, composites and thermoplastics.
l Solsperse 24000 comparable – performance and dispersing efficiency comparable to Solsperse 24000.
Product Applications
l Digital printing inks & analog printing inks
l Architectural and construction protective coatings
l Industrial & transportation coatings
l Composite materials
l Colorants and thermoplastics
Recommended Addition Ratio
The amount of additive (in purchased form) is based on the pigment:
|
Pigment Type |
Recommended Dosage |
|
Organic pigments |
7% – 15% |
|
Standard carbon black |
10% – 20% |
|
High-surface-area carbon black |
40% – 80% |
|
Inorganic fillers & titanium dioxide |
3% – 8% |
Overdosage will impair film hardness, adhesion and cause haze. Insufficient dosage leads to pigment flocculation, high mill base viscosity and weak color strength. A dosage gradient test is suggested to confirm the optimal level. The above data are empirical and the optimum amount should be determined through a series of tests.
Processing Instructions
l Add the powder to the mixture of grinding solvent and grinding resin, and stir at low speed.
l Moderate heating to 50–60°C can accelerate complete dissolution.
l Proceed to the next step only after the system turns clear and free of particles.
Safety Measures
Please refer to the Material Safety Data Sheet (MSDS).
Packaging
l 16 kg iron drum with inner coating
l 200 kg iron drum with inner coating
Warehousing and Storage
l Store in a cool, well-ventilated warehouse below 35°C.
l Avoid direct sunlight and high-temperature heat sources.
l Keep packaging fully sealed against moisture to prevent caking.
l Store separately from strong oxidants, strong acids and strong alkalis.
l The product must be used and handled following the usual precautions for all chemical substances. Consult the MSDS.
