A Biolatex from a proprietary biopolymer nanoparticle technology platform provides a high performance
substitute to the petrochemicalbased binders used in coated paper and paperboard manufacturing processes at a lower cost per pound. The biolatex provides performance that is comparable for important paper properties such as coating gloss, brightness, whiteness, f luorescence, ink
gloss and printability, while providing superior performance to carboxylated styrene butadiene (SB Latex) and styrene acrylate (SA Latex) for water retention, opacity, dry pick, print mottle, porosity (blister resistance) and paper stiffness— one of the more valued paper properties. When added to the paper coating color formulation, biolatex can immediately replace 25% to 50% of SB or SA Latex used in coating processes,
while maintaining comparable-to-superior performance. nanoparticle technology Starch occurs in nature in various plant forms and consists of microscopic granules used for energy storage by the plant. Starch requires water, heat and caustic chemicals to dissolve. Resultant starch solutions have high viscosity at low solids,
a property that limits their use in industrial applications. EcoSynthetix, based in Lansing, MI, and Burlington, Ontario, developed a process that removes the native granular structure and reduces the particle size diameter from approximately 30 μm (= 0.03 mm) to approximately 0.1 μm (= 0.0001 mm) or 100 nm

The advent of synthetic latex is one of the major discoveries in polymer science. Instead of he need to dissolve relatively large (high molecular weight) polymers in a solvent, which limits the maximum % solids for a given target viscosity, polymer colloids or waterborne latexes consist of high molecular weight polymers “hidden” within the colloid particles. Thus the viscosity of a latex or colloid is no longer dictated by the molecular weight and % solids of the polymer, but instead is determined by the number, size and
size distribution of the colloid particles.
