Bob,
3M's Scotch-Weld glues are a specific brand to look for.
There is a good reason why most folks at Home Depot aren't familiar with PUR (Polyurethane Reactive) glues - it is a pro-level option for woodworkers. It is a hot-melt glue and you need
glue guns to heat and dispense the glue. Most everyday glue users will opt for a cheaper and easier solution. There are more affordable PUR options than the 3M products.
Franklin International sells a line of PUR glues and glue guns under the Titebond brand.
If you go this route, you'll get a first-rate bond with fast drying times - very professional results. But, it might be overkill for you.
Check out this article on the American Printer website. It is a trade magazine for the binding industry and looks at adhesives from the pro-perspective.
PUR in Every Glue Pot? - American Printer ArticleThe EVA glue used in a
typical hot glue gun may be a better fit for you. The costs are reasonable, the glue works well (it is one of the formulas that pro-binderies use) and it is a little easier to work with and find in stores.
Of course,
good old PVA glue works great, you just have a slightly longer drying time to work with.
The decision comes down to your specific needs for speed, work volume, and cost.
I have successfully used
PVA glue,
common hot-melt EVA glue,
5 minute epoxies, and
Neoprene rubber contact cement to bind books. They all get the job done and have made durable bindings for me.
Hope this helps,
Andrew
