This binder technology has been used commercially for years because it offers a distinct combination of high abrasion resistance, flexibility, and tactile performance benefits. However, recent market trends place higher emphasis on performance properties that are challenging for these traditional finishing systems to achieve. Such properties include: dirt pick-up and dye transfer resistance, cleanability after soiling, as well as UV, hydrolytic, and thermal stability. Topcoats featuring acrylic-based binders are increasingly competitive due to intrinsic soiling resistance and stability properties; however, replacing more than approximately 25% of the polyurethane-based resin with acrylic-based resin can result in a noticeable loss in abrasion resistance or toughness. The Dow Chemical Company has developed a novel acrylic binder technology designed to offer many of the same advantages of PUD binders, such as toughness, while retaining the enhanced soiling resistance and stability needed to address the stringent demands of today’s market. This paper describes the performance properties attributed to this new binder technology through a systematic validation process.

Novel acrylic particle technology for high performance leather finishing / J. Hoefler in JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA), Vol. CVI, N° 11 (11/2011)

Langues : Américain (ame) Catégories : Cuirs et peaux -- Finition Polyacryliques Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : The Dow Chemical Company has developed a novel acrylic technology for use in leather finishing formulations. Products making use of this unique technology can deliver low gloss finishes with high optical clarity, soft-touch aesthetics and high physical performance. The key enabler in this technology is an acrylic particle that offers comparable gloss, “jetness” and performance properties to many commercially available inorganic and organic dulling materials. The technology is inherently solvent free, and is compatible with existing acrylic and polyurethane resin components as well as conventional cross-linking chemistries.
