PUR has arrived in India. Tony Clark, the bookbinding guru describes the journey of adhesives
History is full of projects that failed at the first attempt and were not proceeded with.
In the case of PUR for bookbinding, for instance (this could have happened in 1990 or around that time). Development chemists said they had found the panacea for the binding trade, a glue that would bond any paper without any spine preparation, (every bookbinders dream).

Discussions on how a binding machine works and the set-up times etc, followed and the chemist’s went away to re-think the project.
