Bonding Uhmw To Aluminum

I did some testing and the bond seems to have a shear strength of about 5000 psi. When it failed it was the bond to the aluminum that failed not to the ptfe. Metal surfaces including steel stainless steel galvanized metals and aluminum often accumulate contamination including corrosion or oxidation and provide bonding challenges.

Use two part epoxy or neoprene based cement.

Bonding uhmw to aluminum. Ultra high molecular weight is the secret of this polymers unique properties. I have used it to glue teflon ptfe to aluminum as well as to ptfe to ptfe. Uhmw pe stands for ultra high molecular weight polyethylene. It will also foam to fill.

For bonding aluminum to dissimilar surfaces with different coefficients of thermal expansion consider toughened 737. Consider es550 or es558. A simple pinch from a flexible container applies a precise drop or bead of cyanoacrylate and world record power. Metal surfaces are.

Roughen both edges that will be bonded the side of the plastic and the side of what whatever you are going to adhere to it using 4 0 sandpaper. If you want instant world record type strength adhesion over a smaller bond area consider 3m scotch weld instant adhesive pr100 with low viscosity for tight fitting parts. The back and forth stroke is about 10 and it runs at 37 strokes per minute. Single component epoxies are ideal for bonding aluminum.

Bonding uhmw to steel i want to attach 25 thick uhmw sheets to the exterior sides of a 12 length of 3 square tubing. Crown plastics durasurf uhmw overcoming bonding challenges crown plastics. When 100 solids fast bonding and flow over a larger area are the answer 3m hot melt adhesives. For very high strength use a metal bonder such as 170 or the original 910.

Clean both surfaces well using a cleaner such as alcohol to eliminate even fingerprint oil. Selecting the correct bonding agent for the applicatio. In my last go round with uhmw and aluminum i roughed the aluminum and plastic with 80 grit sanding cloth wetted the aluminum slightly with a damp rag and then clamped the assembly together with gorilla glue. It seems to be holding well.

All grades will bond aluminum well. Loctite glue for all plastics works very well. Ultra high molecular weight polyethylene adhesion to dissimilar materials for structural bonding what is uhmw. It is the highest quality polyethylene.

Place it in an aluminum dish in a 300 degree oven. Which will be reciprocating inside a section of 4 square tubing. Ultra high molecular weight polyethylene uhmw is a tough wear resistant plastic with low coefficient of friction outstanding impact strength with excellent chemical and moisture resistance and broad temperature range. Its high density polyethylene resin has a molecular weight range of 3 to 6 million.

Gorilla glue is a urethane based product that cures when exposed to moisture.
