Scripset® 540 is a copolymer of styrene and maleic anhydride (>1:1 mole ratio) with approximately a 180,000 weight average molecular weight. The maleic groups have been esterified with a low molecular weight alcohol to impart additional functional properties. It is a fine, off-white, free flowing powder with a faint, aromatic odor. Scripset 540 is readily soluble in alkaline aqueous systems and is typically made utilizing Ammonium Hydroxide, Sodium Hydroxide, Potassium Hydroxide, but Soda Ash, Sodium Borate, and Amines can also be used. Scripset 540 is also soluble in a variety of organic solvents including alcohols, ketones, ethyl acetate and co-solvents (Xylene/Butanol). Solutions made from this powder demonstrate excellent stability under the proper storage conditions. Excellent stability under proper storage conditions Readily soluble in both alkaline aqueous systems and in certain organic solvents Excellent film former High molecular weight Dried films provide excellent water resistance Scripset 540 resin is typically used in surface treatment applications of paper for sizing, porosity reduction and surface strength enhancement. Typical uses outside of the paper industry include applications as a pigment dispersant, emulsifier, binder, and viscosity modifier. High molecular weight, styrene/maleic anhydride copolymer, esterified with a low molecular weight butyl methyl ester. Used as a starch modifier in coatings to give increased water resistance, as an alkali removal component in water and organic-based coatings, as an antiblock component and a solvent in coatings, and as a binder component in inks and photoresist coating. Provides very good stability and film formation.
