Finished Adhesives and Sealants

RSS

Silicone joint sealants from Dow Corning Corp. were selected for use in the reconstruction of the primary runway at Andrews Air Force Base in Prince George’s County, Md.

I am developing an adhesive for an application that requires heat resistance greater than 80°C. A formulation based on a waterborne polyurethane polymer currently provides the best adhesion to the substrate and is a fit for the application process. What approaches can be used to achieve the required level of elevated temperature performance?

For technical applications that require some form of adhesion, pressure-sensitive adhesives (PSAs) usually offer the best value, given their affordability, ease of use and clean application, when compared to alternative bonding options like mechanical fasteners or liquid adhesives.

Industry professionals will be exposed to new trends, technologies and topical expertise at the Adhesive and Sealant Council’s (ASC) Fall Convention & Expo, which will take place next month at the Hilton Minneapolis in Minneapolis.

I'm writing this column in the midst of a very busy week. Sometime between conference calls and podcast recordings, I realized how little time I now need to spend on tasks that—even just a few years ago—took up the majority of my day.
