Pigment Dispersions

Titanium dioxide dispersions

Titanium dioxide dispersions and slurries are notoriously difficult to produce at high solids concentrations due to the high density of the TiOâ‚‚. This high density causes destabilization and eventually separation at the top of the dispersion. Lansperse BIO868 helps to stabilize high active dispersions by maintaining good rheology control, but with light agitation the rheology drops immediately to help in the handling and processing within the end application. This property is noticeable for high solids loading between 60 - 70%, at lower solids levels the dispersion is a nice free-flowing liquid.

Other Pigment Dispersions

  • Yellow 42 60%: Pigment yellow 42, also known as Yellow Iron oxide is a yellow powder in the form of an alkaline oxide. To effectively disperse 60% solids in water add 3% Lansperse BIO868.
  • Red 101 65%: Red 101 is an important inorganic colorant, iron oxide red is characterized high opacity, strong tinting strength, easy dispersibility, excellent light fastness and perfect weather resistance. It is extensively used in concrete, roofing tiles, masonary, paint, coating, rubber, plastic, paper and leather industries. To effectively disperse 65% solids in water add 3.75% Lansperse BIO868.
