The issue you are holding in your hands (whether a physical copy or virtual on an electronic device) is the result of the collaboration of a number of people in various locations around the globe—many of whom have never met!

Packages are chosen based on performance and cost. Specialty materials like anaerobic adhesives need oxygen to maintain their stability and shelf life. These materials were traditionally packaged in low-density polyethylene tubes or bottles to allow air diffusion into the package.

This is a very interesting question. Many adhesives are used in what is called a “zero gap” situation, where the adhesive is applied between two closely fitting surfaces, which are then clamped together.

We’re all about raw materials this month. Our annual Raw Materials, Chemicals, Polymers and Additives Handbook includes definition/use information for key products, as well as supplier details.

The primary forces are shrinkage of the adhesive on curing and large differences in thermal expansion coefficients between the substrates and the adhesive. High stresses can cause delamination of bonds or damage to the substrates, such as glass cracking.

How much time do you think you spend in a day looking at a screen, be it a cell phone, tablet, computer screen or television? I know I’m sometimes guilty of checking my email on my phone one last time before bed—long after I’ve asked my kids to turn off and put away their devices. Research has shown that people spend an average of 8 hrs, 41 min on media devices, compared to 8 hrs, 21 min sleeping a day—a pretty remarkable statistic. Manufacturers of these devices are driving innovation in adhesives and sealants.

Welcome to ASI’s annual Buyers’ Guide, a purchasing and applications resource for raw materials, equipment and services used to manufacture adhesives and sealants, pressure sensitives, and adhesives and sealants products such as tapes and labels. The Buyers’ Guide also includes supplier details for finished adhesives and sealants.
