Ashland adds Aroset PS 5333

Aroset PS 5333 is a pure acrylic pressure-sensitive adhesive that is free of hexane, toluene and vinyl acetate monomer. The adhesive’s high solids and low viscosity mean it can be applied with conventional coating techniques, yet can be run at faster line speeds to reduce applied cost, according to Ashland Specialty Ingredients, a business unit of Ashland, Inc.

Ashland said the new product is a ‘significant addition’ to its existing line of solvent, solvent-free, emulsion and UV/EB adhesives and coatings. Aroset PS 5333 is claimed to shows robust wet properties, and to provide superior pigment acceptance, wetting and stability when coated on release liners. Ashland said that in vinyl graphic and industrial tape applications, this solvent-based adhesive delivers aggressive tack and peel adhesion on a wide variety of substrates. It is said to have ‘great affinity’ for various types of foams and to provide anchorage to monomeric and polymeric vinyl. In testing, it demonstrates enhanced aging performance and good cohesion properties, even at elevated temperatures.

Stuart May, EMEA business director at Ashland Specialty Ingredients, said end users are driving legislative change across Europe to protect the environment, which is moving tape and graphic manufacturers to rethink their products. ‘Aroset PS 5333 adhesive gives them a means to improve their product ahead of changing regulations, so they can maintain compliance well into the future without sacrificing performance.’
