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.

Could you please suggest an epoxy resin, along with a hardener and accelerator, to use as a raw material in the production of a high-temperature-resistant adhesive?

Dr. Dave provides details regarding the use of inorganic vs. organic adhesives for high-temperature applications.

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.

Ask Dr. Dave

What type of adhesives would you recommend for bonding glass to steel that will be exposed from -20-100˚F in an outdoor environment?

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.

How can we ensure full cure when using a UV-cured coating/adhesive on irregularly shaped parts?

Dr. Dave shares tips on avoiding blind areas that do not cure completely on irregularly shaped parts.

All adhesives tend to lose strength on immersion in water. Water acts in two ways on a bonded assembly: It can be absorbed into the adhesive and soften it, and it can degrade the interface between the adhesive and the bonded surfaces.
