R.T. Vanderbilt Company has been selling minerals and chemicals to the pulp and paper industries for nearly 100 years. Mineral pigments for filling and pitch control, enzymes for starch conversion, dispersing agents and thixotropes for paper coatings are offered. The products for pulp and paper are described below:

  VANZYME^® Starch Liquifier
  DARVAN^® Dispersing Agents
  BILT-PLATES^® 156 Pitch Control Agent
  VEEGUM^® T, VAN GEL^® B, VANZAN^® Thixotropes

VANZYME starch liquifier pioneered the enzymatic conversion of starch. VANZYME products are alpha-amylase enzymes that act upon starches to reduce their viscosity by liquefying and partially converting them to soluble dextrins with the formation of a minimum amount of sugars.
VANZYME Starch Liquifier

          VANZYME
VANZYME powder is very useful in batch conversion of starch for size press or coating use. The enzyme activity of VANZYME powder is 4200 SKB.

DARVAN dispersing agents are low foaming dispersants for mineral pigment slurries.
DARVAN Dispersing Agents

          DARVAN 1 Spray Dried
DARVAN 1 Spray Dried is a sodium salt of polymerized alkyl naphthalene sulfonic acids that perform as a highly effective dispersing agent for mineral pigments in a water.

          DARVAN 7-N
DARVAN 7-N is a low foaming sodium polymethacrylate dispersing agent highly effective in dispersing mineral pigments in a water.
  DARVAN 7-N and DARVAN 7-NS Dispersing Agents

          DARVAN 670
DARVAN 670 is a sodium salt of polynaphthelene sulfonic acids. It prevents settling and controls viscosity of mineral pigment slurries.

          DARVAN 811
DARVAN 811 is a sodium polyacrylate dispersing agent. It is a highly effective dispersant for high solids mineral pigment slurries such as TiO₂, calcium carbonate or kaolin clay.

  Filler Minerals from R.T. Vanderbilt Company, Inc.
  Kaolin Clay

          BILT-PLATES 156
BILT-PLATES 156 kaolin clay is an effective pitch control agent. It consists of an extremely fine particle size having high surface area platy particles. Its surfaces absorb soluble or dispersed depositable chemicals (pitch) from pulp slurries.

          VAN GEL B Granules
          VEEGUM T
VAN GEL B and VEEGUM T are industrial grades of magnesium aluminum silicate (smectite clay). These clays impart thixotropic properties with good anti-settling characteristics to paper coatings. These thixotropes are bacterial and enzymatic resistant.

          VANZAN
          VANZAN D
VANZAN D is an anionic polysaccharide (xanthan gum) produced from fermentation of carbohydrates by the microrganism xanthomormas campestris. It is supplied as a creamy-white powder which gives pseudoplastic colloidal solutions in water and is insoluble in most organic liquids. VANZAN has exceptional thickening, suspending and stablizing properties in the presence of acids, bases and salts, and at elevated temperatures. Two grades of VANZAN are available for paper coating applications: VANZAN and VANZAN D. The latter is specifically treated to promote its easy dispersion and accelerated hydration when the pH is increased to >7.
