Waterborne Dispersions from Bayer Offer High Initial and Final Bond Strengths and Customizable Formulations

Denver, CO, April 16, 2012 --(PR.com)-- Adhesive formulators always strive to provide high quality adhesives with strong bond and reliable processing. Replacing solvent-based adhesives with waterborne ingredients can provide improved performance, while meeting stricter environmental regulations. The Adhesive & Sealants Council’s two-day short course on waterborne adhesives offers insight into these trends.

Dr. Jeffrey Dormish, business development – Adhesives & Specialties, Bayer MaterialScience LLC, discussed these topics during his presentations, “Polyurethane Dispersions for Adhesive Applications,” and “Waterborne Polychloroprenes for Adhesive Applications.” Both presentations took place during the Waterborne Adhesives Short Course at the Adhesive and Sealant Council’s (ASC) Spring Convention and Expo, which took place in Denver, April 15-17.

Each presentation provided an overview of the chemistry and manufacturing processes for each class of adhesives. Aqueous polyurethane dispersions provide the basis for many waterborne adhesives, offering a high initial bond strength, resistance to moisture and plasticizers, and several grades that are compliant with Food & Drug Administration regulation 175.105. During his first presentation, Sunday, April 15, Dr. Dormish covered polyurethane dispersions, including application methods, crosslinking and performance.

It is possible to replace the raw materials used for solvent borne adhesives with waterborne polychloroprenes that offer high storage stability without affecting end-use performance. Different combinations of polychloroprene latexes allow formulators to tailor adhesives to target typical contact adhesive applications. Dr. Dormish’s presentation on Monday, April 16, included the principles of contact adhesives, production and microstructure of polychloroprenes, applications and starting formulations, focusing on waterborne products.
