DELTA DC 3750 offers a range of dispersion control additives designed to prevent flocculation and improve the stability of pigment dispersions in coatings, inks, and plastics.
The additives are categorized into low and high molecular weight types, each with specific properties and modes of action for different pigment types.
Proper selection and application of these additives are crucial for achieving optimal dispersion and stability in formulations.
DELTA DC 3750 is a general purpose polymeric dispersing agent for use in water based coatings.
DELTA DC 3750 is particularly effective in dispersing inorganic pigments.
Applications and usage:
DELTA DC 3750 is a sodium salt of an acrylic polymer with a precisely controlled molecular weight.
This offers an excellent balance of viscosity reduction, dispersing property and storage stability of inorganic pigmentsdispersion.
DELTA DC 3750 can be effectively used from matt up to high gloss emulsion paints formulations.
Ideally, it would be recommended to use the ammonium polyacrylate DELTA DC 3750 for high PVC matt formulations for an improved water resistance properties.
DELTA DC 3750 should be added prior to the dispersion process.
0.2-2.0% on inorganic pigment weight.
The optimum addition level will depend on the specific formulation characteristics.
