Scripset 520 Styrene-maleic anhydride copolymer Hercules Vinyl >> Polystyrene & Styrene Copolymers Inks Coatings >> Solventborne Coatings >> Waterborne Printing Inks & Varnishes Soluble in alkaline aqueous system, acetone, ketones, certain esters, ethers, and alcohols Insoluble in water, acids, aliphatic and aromatic hydrocarbons Scripset ® Resins (Styrene Maleic Anhydride Copolymers) as a starch modifier in coatings to give increased oil resistance and water wet-out, 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. Scripset® 520 is a copolymer of styrene and maleic anhydride. A small percentage of the anhydride groups have been esterified with a low molecular weight alcohol. It is fine, off-white, free flowing powder with a faint, aromatic odor. Scripset 520 is readily soluble in alkaline aqueous systems and is typically made utilizing ammonium hydroxide, sodium hydroxide, potassium hydroxide, soda ash, sodium borate, and amines. It is also soluble in acetone or may be solubilized by heating with low moleuclar weight alcohols with which it forms esters. Solutions made from this powder demonstrate excellent stability under the proper storage conditions. Excellent stability under proper storage conditions Excellent film former Very high molecular weight Dried films provide excellent water resistance Scripset 520 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 includes applications as a pigment dispersant, emulsifier, binder, and viscosity modifier. Typical applications are as a surface size treatment for paper, adhesive modifier, emulsifier, binder, pigment dispersant, viscosity modifier, and as an ingredient in coatings for printed circuit board manufacture. Very high molecular weight, styrene/maleic anhydride copolymer. Used as a starch modifier in coatings to give increased oil resistance and water wet-out, 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. Provides very good stability and film formation.
