Just like with most natural products, glues have an expiration date.  You'll notice, especially with your natural glues (protein/gelatin based) and liquid water-based glues, that after they have hit their expiration date they may become moldy and unusable.

What do you do if your glue is expired?

Adhesives are used virtually everywhere in the manufacturing world to keep things together. When trying to bond surfaces, having a reliable adhesive makes all the difference. With so many options available for commercial adhesives, how do you know which is the best for your project?

Those of us at LD Davis are individuals of many talents! Sure, we can manufacture quality animal glue products, and make 3,000 on-site customer visits each year…but did you know we have a resident photographer on our staff?

LD Davis has been manufacturing quality animal glues for over nine decades, but animal glue itself has been around for centuries longer.  In fact, up until the mid-20th century, most glue in use was animal glue, dextrin glue, or other glues composed of natural polymers such as starch adhesives.  Products such as hot melt adhesives and resin adhesives are much newer in comparison to animal glue and other natural adhesives; they have only been used widely for about 60 years or so.
