Title: non-solvent based adhesives
Post by: kahynickel on January 16, 2016, 01:47:19 PM

I teach A-level chemistry. Recently non-solvent based adhesives such as poxy resins and superglues are included in the syllabus. I want to know how these polymers work as adhesives with reference to their structures. i searched on google but no particulars information.

Don't call them poxy resins. You may not like them, but that's not their fault!
If you meant epoxy resins, there's this for a start: https://en.wikipedia.org/wiki/Epoxy
And for superglues: https://en.wikipedia.org/wiki/Cyanoacrylate

Mastics and other building adhesives tend to be waterbased...  they use waterbased emulsions of some polyer or another (acrylics, acetates and the like) filled with some kinda chalky or dolomite type fillers and pigments. The polymers are sticky when still wet and adhere to the surfaces and then cure off.
