What is hydroxyl bonding? I thought I would Google the term and give you the definitive answer. However, when I searched for a definition, I consistently got pages of explanation written in the language of chemical engineers. I’m afraid I don’t speak “chemical-ese.” I found Internet explanations difficult to read and essentially unable to translate and explain the intricacies of chemical bonding. So, having a blog article to write, I thought back to a visit I had with a doctor of chemistry I met at Tremco Adhesives in Toronto many years ago.
