Abstract

This invention is directed to a kit for performing adhesive audits and a method of doing the same. The kit and method can be used to improve the speed and ease with which adhesive audits are performed.

First claim

What is claimed is:

1. A method of performing an adhesive audit on a production line, the method comprising:
a) obtaining a release coating that is liquid at room temperature,
b) applying the release coating to substrate areas to be bonded,
c) bonding the substrate, with a hot melt adhesive, through the substrate areas to be bonded to form a unit on a production line wherein the unit is a filter, bag, box, case, carton or tray,
d) disassembling the unit,
e) removing the adhesive from the substrate with release coating, and
f) weighing the adhesive removed to determine the amount applied per unit.

2. The method of claim 1 wherein the release coating further comprises a colorant.

3. The method of claim 1 , wherein the substrate comprises cellulose.

4. The method of claim 1 wherein the release coating is a water based release coating.

5. The method of claim 4 wherein the release coating comprises polydimethylsiloxane.

6. The method of claim 4 wherein the release coating has a solids content of less than 30% by weight.

7. The method of claim 1 wherein the release coating has release properties within 2 minutes after application and maintains those properties for at least one day.

8. The method of claim 1 wherein the release coating is applied by use of a container with an applicator at one end.

9. The method of claim 8 wherein the container holds no more than 3.4 ounces.

10. The method of claim 8 wherein the container comprises a plastic container equipped with a sponge applicator.
