I was trying to adhere PU (60A) with UHMWPE. For that, I PU liquid mixture (part A and B, purchased from Mcmaster carr, link: https://www.mcmaster.com/8644K24) on
Then I put 75 D machined part in a container and then poured 60A liquid around. Then I let it form over 12 hours. Then I baked at 120F for another 10 hours to cure.
Unfortunately, I noticed that the UHMWPE parts can be easily peeled off from the PU as can be seen from attached figure.
In contrast, I did same thing for PU-60D (instead of UHMWPE) and found good adhesion between PU 60A and PU60D.
Literature suggest that surface treatment of UHMWPE (surface roughening or corona or plasma treatment) may induce good adhesion.
Any insight on adhesion between UHMWPE with PU 60A will be appreciable
Dear Md Nuruddin, polyolefins are hydrophobic polymers, the surface is almost totally neutral. As you said, surface treatment is necessary prior to adhesion. Chemical and physical techniques are used to impart polar groups and to change the surface topology. My Regards
