George zafiropoulos kallithea athens greece. The problem is no glue will stick to the aluminum not even gorilla glue very well. For bonding aluminum to dissimilar surfaces with different coefficients of thermal expansion consider toughened 737. Modern adhesive technologies utilize both singleand two coat adhesive formulations with the preference depending upon the service needs of the bonded assembly.

Historically several bonding methods have been employed within the rubber industry in an effort to achieve a dependable and durable rubber to metal bond. The aluminum is well slick because that is the finish it ends up with. Thicker aluminum oxide layer increased porosity and increased strength brittleness. Although aluminum is a common bonding substrate for epoxy anodized aluminum can present its own set of bonding problems.

Because i ve already googled myself so i m asking for someone that s had success with strong bonding between anodized aluminum surfaces or bare aluminum surfaces not just someone to tell me to use super glue because you think it will work. It is very flexible and soft. I do not know for sure what kind of rubber it is but it is black and happens to be electrically conductive. Mating faces electrical bonding is achieved by having a flat face on each part of the assembly that mates with another part.

For very high strength use a metal bonder such as 170 or the original 910. All grades will bond aluminum well. Question we re having a problem with glue not adhering to anodized parts made from extruded 6063 t6 aluminum and finished with heavy etch and black anodize per mil a 8625 type ii class 1. We are seeking a type of glue to bond aluminium parts in fact we have aluminium strips and we want to bond them with aluminium tubes.

Anodizing for pre prep bonding bridges the gap between the metallic and composite worlds as it provides a superior surface in many applications on aluminum components for bonding to these composites.

The anodic coating is integral to the base metal and the porous anodic film is wondrously receptive to primers and adhesives.

Anodized aluminum is an electrolytically induced passivation process where several physical changes occur to the surface including. Before gluing i rough the rubber with 150 sandpaper. 10 31 2019 12 54 pm 2.
