  • WALLBOARD BINDER Starch is a dual-purpose starch, acting as both a binding and adhesion agent. Its primary function is to form an adhesive bond between the paper liner and gypsum.
  • STAR*POL® Starch Polymers are water soluble polymers, ideal for use in a range of building products and adhesive formulations.
  • STARAMIC™ Modified Corn Starches are modified corn starches pregelatinized to be soluble in cold water. They are easily dispersible, highly substituted, nonionic water-soluble polymers designed for use at lower solid levels in wall treatments, adhesives, tile mortar, tile grout, and oil-drilling mud, among other applications.
  • STADEX® Dextrins are useful in a variety of products that require a liquid or dry binder. STADEX® Dextrins range from lightly thinned to very highly hydrolyzed, offering a wide range of cold-water solubility and functionality.

We are a paper starch market leader in North America. Our starches are used in papers of all grades, to increase strength, and improve retention, drainage, and surface properties. They are utilized in both surface sizing applications at the size press and as a cost-effective binder in pigmented coating applications. Our extensive range of wet-end starches are relied upon in applications ranging from printing and writing to packaging and tissue production – get in touch to find out more.
