Acrysol

Description

[Rohm & Haas] A registered trademark for a series of acrylic dispersions. An early reference lists Acrysol® resins as solutions of Acryloid® resins (Brady 1971). However, the Acrysol® resins sold currently are milky white emulsions polyacrylic acid mixed with acrylic copolymers or sodium polyacrylate. Neutralization of the emulsion with any basic compound causes it to clarify and thicken. Acrysol® resins are used as thickeners in acrylic paints, coatings, and adhesives as well as fabric sizes. They are also used as emulsifying agents. By themselves, Acrysol® resins dry to a transparent, colorless film that can be slightly brittle and hygroscopic.

• Acrysol® ASE-60: used as a thickening agent
• Acrysol® ASE-75: linear polyacrylate
• Acrysol® GS: used as a thickening agent
