Specialty Surface Starches
National Starch Papermaking Innovation offers a variety of specialty surface starches that deliver outstanding properties:
- CATO-SIZE® Cationic Surface Starches:
CATO-SIZE starches promote effective film formation, which improves surface strength and printability. Because of the fiber substantive nature of CATO-SIZE surface starches, mill effluent BOD reduction is an additional benefit realized with CATO-SIZE use.
- KOFILM® surface Starches
KOFILM starches reduce functional additives usage and improve coating holdout, useful in the production of silicone release grades and label stock.
- FILMKOTE® Hydrophobic Starches
FILMKOTE hydrophobic starches provide a barrier of oil and grease resistance from dry-end applications because of their oleophobic and superior surface oriented, film-forming properties. The use of FILMKOTE can eliminated the need for expensive fluorochemicals entirely. This simplifies surface treatment formulations and reduces chemical handling while decreasing total manufacturing costs.
- RediSIZE - Liquid Natural Polymer (LNP) for ASA Emulsification
Specially designed for maximizing ASA sizing efficiency through the development of uniform ASA emulsion quality. ASA emulsions produced with RediSIZE have a smaller average particle size leading to greater surface area for better ASA retention and a tighter particle size distribution which promotes emulsion stability and a reduced ASA hydrolysis rate. The benefit to the papermaker is improved finished paper/board quality and machine cleanliness.
- Typically allows for lower ratios of emulsifying agent to ASA than with mill cooked starch. This leads to reduced ASA sizing costs per ton of paper/board produced.
- De-Coupling of wet end starch and ASA emulsifying agent. This allows for greater flexibility in choosing a wet end starch that can
- Maximize strength development and retention without compromising ASA emulsion quality.
