ALCOGUM® L-291 is an acrylate-based emulsion copolymer supplied at 25% active solids in water. The process employed in the manufacture of ALCOGUM L-291 allows fine control of the polymer structure and molecular weight to meet the specific rheology and water retention requirements of the paper and paperboard coating industries. Control of these properties can have a positive effect on runnability and surface properties. ALCOGUM L-291 was developed for use in lightweight coating formulations that require additional water retention and reduced blade pressure for improved coater runnability.
It possesses efficient viscosity build in most coating solids, provides excellent water retention, liquid for ease of handling and metering, shear thinning flow characteristics.
