The specialty chemicals value chain has risen to the challenge of retooling to fill large supply gaps for sanitation products, packaging containers and inks, and other essential products to meet spikes in demand as an outgrowth of the COVID-19 pandemic.

We assemble steel panels with welding and screws. Can we replace these with an adhesive?

At the beginning of the year, and even as recently as March, the extent of our shared health crisis could not have possibly been imagined. Very quickly, however, following updates from national and international health organizations and the federal government, everyone, including all of us at the Pressure Sensitive Tape Council (PSTC), began to make strategic decisions regarding how to not only navigate the perilous situation, but how to move forward.

The Pressure Sensitive Tape Council defines a pressure-sensitive adhesive (PSA) as requiring two things: aggressive and permanent tack, and adhesion with finger pressure. This simple definition makes the concept of a PSA easy for anyone to understand.

In collaboration with Origin, Henkel recently announced that it has leveraged its ability to carry out biocompatibility and mechanical testing at its facility in Concord, Calif., and provided a range of 3D-printable medical photopolymers designed for use on Origin’s material development systems. 

The potting of electronic components involves filling the assembly with a compound such as liquid resin (e.g., epoxy, silicone, polyurethane) to protect it from environmental or use conditions like moisture, humidity, and vibration. Any air entrapment in the potting compound can result in air bubbles that may cause performance problems in the finished component.

NASA has selected Masten Space Systems of Mojave, Calif., to deliver and operate eight payloads—with nine science and technology instruments—to the Moon’s South Pole in 2022 to help lay the foundation for human expeditions to the lunar surface beginning in 2024.

Henkel is among 155 major global companies from 34 sectors that have signed a statement urging governments around the world to align their COVID-19 economic aid and recovery efforts with the latest climate science.

Cleaning and surface pretreatment are directly related in many industries. Traditional pretreatment methods such as alcohol wiping or air nozzles are used to clean off contaminants and prepare surfaces for adhesion.
