How to make hot glue for specific types of weather
« on: August 08, 2018, 01:34:13 PM »

Hi there, am new. My industry uses hot glue a lot and I would like to make my own.  Can you tell me how to make a good hot glue built for very hot weather and cold and what he chemical composition is that makes it good for eachapplication. Or point me to a good resource to read up on this as I am having a hard time finding any. Thanks!

Welcome, Justadentguy!

https://en.wikipedia.org/wiki/Hot-melt_adhesive
"The composition is usually formulated to have a glass transition temperature (onset of brittleness) below the lowest service temperature and a suitably high melt temperature as well."

Did you try existing hot-melt adhesives at the cold and hot temperatures you wish? There may very well be some that fits, then you can buy it (cheapest way if you're a consumer for limited amounts) or analyse and produce it (meaningful only in huge amounts).

I vaguely suppose that irregular composition, for instance with varied side chains at varied distances, widen the operation temperature.
