It sounds like you sell to several different markets. Although there is some overlap of silicone or polyurethane markets, they are often used in distinct applications.

We use an acrylic UV adhesive to bond and coat a complex medical device, and get areas where there is incomplete curing. How can we improve this?

Can you help us to get rid of the mess created from using fumed silica in our silicone and polyurethane adhesive manufacture? It is so lightweight that it covers the entire factory.

We have a customer who wants to use an adhesive-backed expanded PTFE gasket strip on a steel substrate. However, the customer wants to be able to remove and reapply the strip without losing adhesion. We do not make ePTFE gasket strips, but we have imported some samples for the customer to test. They are not satisfied with the results. I must admit, I am not surprised. Is there such a thing as a PSA that can be removed and reapplied a number of times without losing adhesion?

Polyurethanes can be one- or two-component systems. The single-component systems comprise a polyester or polyether polyol that has been end-capped with an isocyanate.

Do reactive acrylics and anaerobics behave like epoxies in terms of curing and properties like heat resistance?

What is the difference between a hardener, a primer, an accelerator, and an activator for adhesives and sealants?

Longtime readers of this column may note that I have always been a fan of silicone sealants; however, I worked for a manufacturer of these materials for many years, so I hope I can be totally objective. I have no doubt that the durability and longevity of silicones cannot be exceeded in most applications. However, I can offer you several observations from my personal experience using them at home.

Adhesives are often a better way to assemble plastics than by using mechanical assembly with fasteners. For example, fiberglass composites are routinely bonded with epoxy or reactive acrylic adhesives in the automotive and marine industries because they give high strength and durable bonds.

What are the pros and cons of using pressure-sensitive tape adhesives in place of liquid adhesives in the assembly of electronic devices?
