Instructions for use:
When applied on one side, couple and press while the glue is still wet. When applied on both sides, coupling can be done immediately, either after 3 minutes or up to several hours.

 
Open Time:
Up to 24-48 hours, depending on the amount of adhesive used and on the kind of support. If the open time is exceeded, bonding can be made after having warmed up at 60°C the material to bond.

What’s the difference between the three types of glue?

• 1816B: High Strength: 1816B is used for permanent bonding on a wide majority of materials (leathers of various type, all the types of reinforcements, etc). It can be used in applications that do not require sewing (bag panels without stitching, credit card pocket of wallets, handle of bags, stitchless uppers in sandal or casual shoes, stitchless straps, belts, bracelets, etc).

• 9015ST: Medium Strength: 9015ST can work for auxiliary bonding on critical materials (plastics, etc), as it has a good anchoring on all types of substrates; but in some cases it can make also a permanent bonding (on cardboard reinforcements, genuine leather with no high content of oils).

• 9004: Low Strength: 9004 is for auxiliary bonding only. That means it is used to join pieces that later will be stitched. It’s a perfect glue for positioning and holding the materials until they go into sewing process.
