Borchi® Gen 1757

Dispersant for Bismuth Vanadate Pigments

Borchi® Gen 1757 is a VOC-free dispersant that improves bismuth vanadate pigment dispersions in water- and solvent-based systems. Also known as C.I. Pigment Yellow 184 from Colour Index International, bismuth vanadate is a yellow inorganic pigment that forms from a reaction of bismuth nitrate and sodium vanadate.  
Benefits of Dispersants for Bismuth Vanadate Pigments
Benefits of our Borchi® Gen 1757 dispersant for bismuth vanadate include enhanced color development, superior opacity, higher b* value than market leading dispersants, and lower viscosity at high pigment loading (which, in turn, provides excellent pigment wetting). Storage stability and anti-settling are improved when this dispersing agent is used in combination with our Borchi® Gel PN rheology modifier for low shear thickening in water-based systems.   Borchi® Gen 1757 has been tested with various bismuth vanadate pigments, including DCC® Yellow RMXS from Dominion Colour Corp.

Features

  • Borchi® Gen 1757 is a hybrid wetting and dispersing additive, providing a combination of various principles of pigment stabilization in bismuth vanadate pigment dispersions
  • Excellent with high loading bismuth vanadate concentrates
  • Produces vibrant color and superior opacity with a wide range of bismuth vanadate pigments

Applications

  • Coatings
    • Architectural
    • General Industrial
    • Automotive
    • Protective and Marine

Dosage

Active on pigment loading:

  • Bismuth vanadate pigments: 10 – 20 %

The exact dosage for bismuth vanadate pigment dispersions should be experimentally determined through a ladder study. Borchi® Gen 1757 should be added to the mill base before adding the pigment.

Storage

Protect from the effects of weathering and store at temperatures between 5 and 30 °C. Once opened, containers should be resealed immediately after each removal of the product.
