  • Liquid composition for improving strength and water repellency of cast cellulosic fiber products
    Patent number: 5358554
    Abstract: Paraffin wax emulsion is combined with alkali metal silicate solution to form a stable liquid mixture conferring increased strength and water repellency when applied to cellulosic fiber mat products such as paper and paperboard. This product can be varied in application levels and component ratios such that strength and hydrophobicity and recyclability can be optimized, depending on the final product requirements.
