The continued transition away from brick-and-mortar to ecommerce brings demand for packaging innovations that enable faster delivery and better content protection from shock or temperature variations.
The shift from brick-and-mortar to digital shopping had been under way for some time when the COVID-19 pandemic hit. Since 2017, ecommerce revenues have risen from an estimated $1.4 trillion to $2.4 trillion, or about 2.7% of global output.
Can you recommend suitable materials for packaging a sealant that is sensitive to atmospheric moisture? Additionally, we can do accelerated humidity testing of filled packages, but how do we correlate these with shelf life?
You can obviously package your moisture-sensitive sealant in glass or metal cans or tubes, which will totally prevent moisture ingress. Aluminum tubes are widely used for this type of product, as long as you have good crimps.
I have worked with companies that manufacture superglue and polyurethane glue, both of which are single-component, no-mix adhesives. Superglue, which is the common term for cyanoacrylate adhesive, has been around for about 60 years. In contrast, the polyurethanes are about 20 years old in the retail market and somewhat older in professional woodworking. I admit to using both types of adhesive regularly.
The global adhesives and sealants market grew from approximately $45 billion in 2010 to around $63 billion last year, according to The Adhesive and Sealant Council’s recently released “2020-2023 North American Market Report for Adhesives and Sealants, with a Global Overview.” During this period, over 200 patent applications (simple family groups) in the technical fields of adhesives and sealants were filed across the five major IP jurisdictions (US, EU, CN, JP, KR).
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.
School closings and stay-at-home orders due to COVID-19 have forced many parents around the world to become true activities directors for their households—whether they like it or not. This can be stressful for everyone involved, but I’ve been amazed at some of the ambitious projects I’ve seen families undertake over the past few months using simple household items.
It may be a one- or two-part system. We need temperature resistance up to 500˚C, and the adhesive will be applied to fill small gaps in a hot mild steel structure. The required initial setting time is 5 min.
Engineers, architects, specifiers, facility managers, and homeowners must spend time analyzing what performance levels can be obtained by the adhesive and sealant products that are available to them for the environments in which they are being used.
With increasing consolidation among adhesives manufacturers and the raw material suppliers that support them, global product formulation and availability of materials used in these formulations continue to grow in importance.
Dr. Dave explains why this type of application can often be tricky, particularly due to the large differences in thermal expansion coefficients between the glass, the steel, and the adhesive.
You don’t indicate which substrate is on the outside, and this does make a difference in the possible choice of adhesive. Epoxy adhesives were traditionally used for this application, but they should be used with care as they may be too rigid.
