Adhesive for bonding Delrin to polyester powder coated surface
Adhesive for bonding Delrin to polyester powder coated surface
(OP)
Hello,
We have an application involving an injection molded Delrin cap being inserted into an aluminum extruded door slat that is powder coated.
This application is similar to a roll up door on a hurricane shutter.
The current attachment method is a friction fit between the delrin end cap and the extrusion. The cap fits inside the core of the extrusion. A snap tab that would project through a hole in the slat would provide good mechanical retention, but this will involve more expensive tooling and extra modifications to the slat.
Can someone recommend a good adhesive for bonding delrin to a powder coated surface. I believe the powder coat is a polyester type.
Thanks,
Kyle

DuPont will have data if you ask them.
3M seem to have the best adhesives for "difficult" plastics
Super Glue will do as good as any store bought product
