DISPERPLAST® 1148 is a wetting and dispersing additive for PVC plastisols, designed to improve the incorporation of inorganic pigments and fillers. It enhances color strength, reduces viscosity, minimizes settling, and prevents plasticizer separation. This liquid additive functions as both a dispersant and wetting agent, making it ideal for PVC plastisol applications. It is compliant with the Clean Air Act (CAA) and the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). The chemical name is c21-28 alkane.

Functions: Dispersant, Wetting Agent

Chemical Family: Alkanes

End Uses: PVC Plastisols

Features: Anti-Settling, High Color Strength, Higher Solids Content, Improved Dispersion, Reduces Viscosity

Synonyms: Hydrotreated light paraffinic distillate (petroleum)

Industrial Additives Features
Key Features
  • DISPERPLAST® 1148 reduces the viscosity of pigmented and filled PVC plastisols.
  • It is particularly recommended for inorganic fillers, zinc oxide and blowing agents (azodicarbonamide).
  • The product enables a greater solids content, improves the color strength of the pigments and shortens the dispersion time.
  • It also prevents any separation of the plasticizer.
  • The tendency to settle is reduced.

Applications & Uses

Industrial Additives End Use
Use Level
1 - 3% (Zinc oxide), 1 - 2% (Blowing agent), 1 - 3% (Inorganic fillers), 1 - 3% (Inorganic pigments)
Processing Instructions
  • The additive should be added to the liquid components prior to incorporating the solids.
  • DISPERPLAST® 1148 can be used in either a liquid, solid or partially solid form.
  • The product efficiency is not influenced if it is carefully dispersed in the plasticizer.
