Who exactly doesn't understand terms like "bonding agents" and/or "adhesives" ? I wouldn't expect to find that demographic well represented at a tech product site like this one.
Those for whom English is not a first language, or perhaps even second or third?
And as much as this site is all about tech products, that does not mean the users of those products are - or even need to be - technically savvy. One might even say that a significant part of Apple's DNA is in making highly complex products so easy to use that no special skills or knowledge is needed.
