WESTECH

WESTECH

A surface applied cationic potato starch for paper grades that require superior film forming properties such as increased surface strength, lower size-press solids, greater brightness and opacity.

Features

Important Properties of WESTECH Products:

  • Superior film strength
  • Superior film forming
  • Cationic charge
  • Proprietary chemistry
  • Low gel temperatures make the WESTECHS easy to cook
  • Clear films

Applications

Successful applications of WESTECH starches include:

  • Several grades: Elimination of picking and dusting problems.
  • Highly filled alkaline text papers: 20 to 40 pounds per ton size press pickup with improved optical properties. Because starch reduces both opacity and brightness, the less starch pickup the better the optical properties.
  • Text paper with recycled content of 75 to 100%: Size press pickup of 20 to 40 pounds per ton.
  • 35 pound opaque: Equal pickup of a WESTECH and cationic corn, yet gave equal opacity with 50 #/ton more filler and a 75% reduction in TiO2. WESTECH also gave a higher Scott Bond and pick test.
  • Grease and oil resistant papers: Increased 3M kit values.

Availability

WESTECH high-performance starches are available in three viscosity ranges:

  • High Viscosity starch for very low solids or thermal conversion: WESTECH16.
  • Medium Viscosity starches for high performance on the size press: WESTECH17-18-19.
  • Lower Viscosity starches for higher machine speeds and coating: WESTECH 20-21.

Additional Applications

Other proven potential uses for WESTECH starches include:

  • A solution to dusting and picking problems.
  • Because of their superior strength and cationic charge, WESTECH starches can be used in the wet-end while being used in the size press. This eliminates the need for a separate wet-end starch cooking system.
  • Being cationic, broke with WESTECH surface size won't add anionic trash to the furnish.
  • WESTECH starches can be used on functional papers such as OGR or to replace PVA running at 3% solids and 35 pound per ton size press pickup.
