K-SPERSE® Dispersants

K-SPERSE additives are highly effective dispersing agents for organic and inorganic pigments used in the formulation of non-aqueous and solvent-free coatings and inks. They can be categorized into three distinct groups:

K-SPERSE liquid products - 131, 132, 152, 152/MS
K-SPERSE powder additives - 6501, 6502
K-SPERSE polymeric dispersants - A503 and A504

K-SPERSE liquid products are utilized in a broad range of resins including acrylics, alkyds, bitumen, epoxies, polyesters, and polyurethanes. They are particularly effective for carbon black, phthalo blue and iron oxide pigments. Typical advantages are:

• Higher pigment loading
• Faster dispersion time at lower use levels
• Better color development and gloss
• Greater transparency of transparent pigments
• Improved humidity and corrosion resistance
• Improved cure response

Developed specifically for powder systems, K-SPERSE powder additives offer similar advantages to their liquid counterparts plus :

• Improved hiding power at lower film thicknesses
• Improved dispersion of fillers allowing faster production through extruders
• Ability to withstand high processing temperatures
• Ability to be used in rubber and plastic masterbatching

The new polymeric products have similar advantages and have been designed to:

• Allow 100% solids formulations
• Lower pigment paste viscosity with higher pigment loading
• Eliminate need for synergist
• Have no interference in free radical UV systems
• Little or no effect on the cure of amino resins or isocyanates
