    Technical Details & Test Data

    Titanium Dioxide Dispersions

    Titanium dioxide dispersions and slurries are notoriously difficult to produce at high solids concentrations due to the high density of the TiO₂. 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.

    Formulation Examples

      %
    Titanium Dioxide 65
    Lansperse BIO868 3.75
    Biocide as required
    Dfoam AX1 as required
    Water 31.25

    Method of manufacture :

    1. Prepare a millbase
    2. Manufacture the dispersion using an Eiger Torrance bead mill

    Note: An alternative method is to use a high shear homogeniser


    Rheology over time

     

    Viscosity - Din Cup 4
    Initial 9 sec
    Week 1 11sec
    Week 2 23 sec
    Week 4 93 secs

    After 5 months storage the dispersion is still mobile and pourable.


    Particle size over time - microns

     

    D90 particle size
    10 mins 0.448
    20 mins 0.447
    40 mins 0.448
    60 mins 0.45

    Extremely fast reduction in particle size noticed even after 10 mins


    Conclusion : Lansperse BIO868 offers fantastic dispersing properties for titanium dioxide dispersions and is far superior than many of the commercially available synthetic versions available in the marketplace. It gives a high solids loading along with good rheology and fast reduction of particle size.

    Packaging & Availability

    Packaging Type

    Bulk,

    Drums,
