How does glue work? And why are some glues absolutely horrible while others work great?

609 views

Therr are many types of glue including: PVA, gluesticks, super glue, etc. Im wondering, why some are better than others and why some glues don’t work at all? The typical school glue stick can sometimes barely glue a sheet of paper to another while some glues can stick buildings together.

Different types of glues.

Some glues harden and simply bind.

Some glues stick to a surface.

Some glues chemically alter the surface and bind to it.

Se glues melt things and fuse them together.

By altering the composition or chemicals in the glue, you can make it more or less sticky. More or less flexible, or brittle and breakable.

So many different types. A terrible glue is just an incorrect choice.
