Product Spotlight: PUR Glue

Posted on October 06, 2011 by L.D. Davis Industries, Inc

Animal glue manufacturers are few and far between. In fact, there are only two major animal glue manufacturers in the United States, and we are the largest. Animal glue, or hide glue, is available through distribution companies throughout the country and the world, but do not confuse animal glue manufacturers with distributors. On the contrary, we manufacture our own animal glue, but we are a distributor for other types of glue that we don’t manufacture, such as fugitive glue, hot melt, and PUR glue, or Polyurethane Reactive Glue.

What is PUR Glue?

PUR glue is a specific type of hot melt glue. 

PUR glue is a more recent development in the hot melt world. They polymerize when applied, forming a much stronger bond than other hot melts. It is quite flexible and can be used in a wider range of temperatures than most hot melts. PUR glue is often used in perfect binding as book binding adhesive.

Our animal glue is also used in other methods for book binding adhesive.


Advantages of Using PUR Glue

The bonds occur when the chemicals in the glue draw moisture out of the air. PUR glues are incredibly strong and flexible, and work beautifully as book binding adhesive using the perfect binding method on difficult jobs.

Like most hot melts, they tackify immediately, although PUR glues do require a 24-hour curing period. Common uses for PUR glue include bookbinding spine glue in certain binding applications. Other bookbinding methods depend on animal glue manufacturers like L.D. Davis for hide glue to get the job done correctly.


Main Uses

PUR glue is often used in the following industries:

  • Packaging,
  • Woodworking
  • Electronics
  • Shoes
  • Printed film

L.D. Davis has been manufacturing eco-adhesives for over nine decades. In more recent years we have expanded our horizons to distribute hot melts, PUR glue, and other types of adhesives to fit your needs.

Whatever the application, we will come up with an adhesive solution.
