Domestic demand for construction chemicals used in on-site applications is projected to grow 8.2% per year through 2018 to $12.1 billion, according to “Construction Chemicals,” a recent study from The Freedonia Group Inc.

Two-part adhesives are an ever-growing segment of the adhesive and sealant industry, with applications in aerospace, construction, automotive, consumer goods, and the DIY/repair sectors.

Through quantitative measurements of sealant structure and flow behavior, rheology helps formulators understand the relationship between formulation components and their impact on application properties.

Tertiary amine catalysts used for manufacturing polyurethanes and polyisocyanurates are known to degrade over time, producing products such as aldehydes that can directly contribute to emissions of organic compounds.

PPG Industries’ aerospace coatings group has installed the first commercial system in the U.S. for application of its aerospace electrocoat (e-coat) primer to aircraft parts at the U.S. Coast Guard Aviation Logistics Center in Elizabeth City, N.C.

An automotive supplier uses a machine vision system to inspect up to 900 parts per min to substantially improve quality and productivity. The system checks for the presence and uniformity of a bead of sealant applied to the interior of a metal canister (see Figure 1).

The coating process is one of the most complicated steps in the production of automotive ignition coils. Since it can also be the most expensive, many automotive suppliers are hesitant to implement complex machinery.

It is no secret that the performance of adhesives and sealants is advanced through polymer science.

I have a confession to make: When I was growing up, I hated country music.
