DeCAL 2042 – Sodium Polyacrylate Dispersant

A low viscosity product used to disperse inorganic pigments and fillers in water-borne systems.


DeCAL 2042 is especially suited for use in silk and gloss emulsion paints where its compatibility with glycols maintains the gloss of the system. DeCAL 2042 can also be used to disperse fillers and pigments in many products such as tile adhesives, grouts, fillers and water-based adhesives and glues. It is also used to stabilise dispersions of clay in ceramic casting slips.


  • Ideal dispersing agent for water borne high gloss coatings containing polypropylene glycol and other glycols used to promote wet edge time and film coalescence.
  • Effective at high temperatures above 100°C over a pH range of 5 – 12.
  • Offers much better stability and improved shelf life for water borne paints and coatings.
  • Very high pigment loading can be achieved when thoroughly mixed with water before adding pigments and fillers to the system using high shear mixers.
