PROVIDING QUALITY STARCH PRODUCTS AND TECHNICAL SOLUTIONS TO THE PAPER AND FOOD INDUSTRIES

WESCOTE®

WESCOTE®

Highly derivatized product for use as a coating/size press additive. Characteristics include water holdout similar to CMC and the strength of synthetic binders while forming a very flexible film at a lower cost than CMC or synthetic binders.

Features

Important features of WESCOTE® include:

  • Highly derivatized
  • Has the water-holding characteristics of CMC
  • Very flexible film
  • As strong as synthetic binders
  • Produces paper that prints with little dot gain and high blister resistance
  • Custom made for each customer's application. Our sales and service personnel work closely with mills to match the mill's viscosity requirements.
  • Available in a wide variety of viscosity ranges.

Applications

Successful applications of WESCOTE® products include:

  • Opaque papers – Replacing more expensive binders at equal or improved paper machine runnability and printability while reducing costs.
  • Coating formulations - Replacing CMC to reduce costs.
  • Coated two side - Produced a C2S solvent holdout sheet that did not blister.
  • Paper plates – giving grease resistance.
  • Fine papers – As an additive to size press starches to improve ink-jet printing, reduce linting and milking and increase surface strength.
  • Pet food bags – replacing fluoro chemicals
  • LWC roto – replacement of latex

WESCOTE® Case Study - Trial & Results

This trial consisted of replacing WESCOTE® as a CMC & HES in #2 & #3 LWC Grades. The objective was to make the process more cost effective by replacing CMC and ethylated corn starch in current coating formulas.

Coating formula was changed in accordance with the following:

  • Replaced 70% of the CMC with Wescote® on a 1 part CMC to 0.8 part of Wescote® basis
  • Replaced the HES with Wescote® on a 1 part HES to 0.4 parts of Wescote® basis
  • Reduced crosslinking resin by 70%

The mill trial resulted in a success.

  • The paper was commercially printed and tested.
  • The print tests showed a 30% improvement in print quality.
  • Mill savings were calculated at $500,000/year.
