If you're having issues with glue adhesion, your first thought may be to add more glue.  When it comes to glue, more isn't always better. 

One of the first questions potential customers want to know when they call our company is: How much does your glue cost? 

When manufacturers consider switching glue vendors, cost is a top concern. Although this is a very difficult question to answer, I will try my best to explain some glue cost drivers. Simply put, you are shopping for a glue that will work properly without significantly driving up your costs. This sounds very straightforward but, believe it or not, there are many details we need to recommend the right glue. Each of these details may adjust the formula, and drive the glue cost (up or down).
