Product Description

Alcohol-soluble Solid Acrylic Resin for inks

Flexographic and gravure printing is widely used for printing in the packaging industry. Since the ink most must dry by evaporation from the substrate, the vehicle for the ink must be a volatile solvent. Alcohols have been found to be quite suitable solvents for this use. Acrylic polymers have been used as binders for these inks. these acrylic polymers are the most alcohol-soluble. Accordingly, it would be desirable to provide a more alcohol-soluble acrylic polymer which is a good binder for these flexographic and gravure inks.

SA-601 is a copolymer of ethyl methacrylate and butyl methacrylate, which can be dissolved in alcohol. These acrylic copolymers of SA-601provide an improvement over the acrylic polymers used hereto fore as binders for flexographic and gravure inks. These copolymers provide improved alcohol solubility and printability while also providing good crinkle adhesion, thermal lamination bond strength and adhesive bond strength for this use.

  • Characteristics and Advantages
  1. is a copolymer of ethyl methacrylate and butyl methacrylate.
  2. is an excellent binder for applications of plastic coating, flexographic inks, gravure inks, wood finishes lacquers and BOPP film adhesions.
  3. is soluble in alcohols, esters, ketones, aromatic, glycol ethers and glycol ether acetates.
