OREANDA-NEWS. Although their applications are diametrically opposed, the two new pressure sensitive adhesives (PSA) from Ashland share the same acrylic emulsion base chemistry. Aroset APS 1295 is a coater-ready adhesive for permanent applications while Aroset 2750 adhesive is designed for temporary ones.

Aroset APS 1295 acrylate emulsion delivers high performance with a more environmentally compatible profile than the solvent-based adhesives typically used in permanent tape applications. It provides good adhesion to variety of surfaces and high cohesion, so it performs admirably in tapes used in building and construction, house wrap splice and industrial assembly. Aroset APS 1295 adhesive is also well suited for use in permanent labels and decals, and in overlaminating films.

On the other end of the spectrum, Aroset 2570 PSA allows tapes, films, and paperbased materials to be easily removed or repositioned, even after long-term aging. It is well suited for masking tapes, labels and graphics. It is also excellent in resealable consumer and industrial packaging for wet and dry goods. This includes items like baby wipes and moist towelettes. Aroset 2570 adhesive provides good peel adhesion to variety of surfaces and does not contribute to residue build.

“Aroset 1295 PSA combines good adhesion and cohesion, resists water and is able to form bond at temperatures as low as -20°C,” said Zhaohui Sun, industry manager, pressure sensitive adhesives, Ashland. “Aroset 2570 PSA features low peel build and long-term removability. These kinds of features make it easy for manufacturers to formulate for their specific need and achieve the performance they demand, in removable or resealable products.”
