Adhesive for Powder coated Surfaces
Adhesive for Powder coated Surfaces
(OP)
Hello,
I'm new to the forum and signed up to get some guidance on an adhesive issue I've run into on a hobby project. I'm trying to bond cloth to a powder-coated steel framework and am having issues with adhesion. Any conventional solvent based adhesives I've tried exhibit very poor adhesion. Most likely due to the low surface energy of the powdercoat. I'd appreciate any guidance and recommendations on some adhesives that I should consider with reasonable working times. I'm likewise open to any surface modification recommendations that would allow the use of conventional adhesives however keep in mind I really don't have the capital to invest in plasma or corona treating equipment.
Any and all suggestions are most appreciated!
Thanks,
Ron

Have you tried abrading the powdercoating (e.g. sandpaper)?
After solvent cleaning and abrading, I would use a two-part epoxy for the adhesive.

You are judged not by what you know, but by what you can do.

The powdercoat used is a polyester powder coat. I tried using a 3M 08301 Fast Tack Trim Adhesive which is a rubber based contact adhesive in a hexane solvent. I've used it before to adhere cloth and vinyl to painted surfaces without issues which is what lead me to believe there is something peculiar with the polyester coating that prevents adhesion. It's either something leaching out of the coating or it is low surface energy preventing a good bond. As a really rough test, water just beads up and does not wet out on the surface like it has a coating of wax on it. The powder coat is really tough to score but I'll try hitting it with some 80 grit followed by an acetone wipe to see if that increases adhesion before I look to other adhesives.

You might try using a de-waxing solvent first.
