Glue help - Rubber handle on PVC

[Jlomb436]

Good afternoon everyone.

I decided to mount an "Oh Sh!t" handle on my boat to grab on to instead of using the rope. I went to the local inflatable shop to buy everything and they gave me some instructions along with package glue (2 speerate contains, one smaller than the other). However, when reading instructions here online for something similar, those instructions conflicted what it says on my paper instructions.

In short, I have documentation from them that is describe as a repair, so I can assume it's meaning a patch (PVC on PVC). It says all surfaces should be sanded.

However, I've read on here that the PVC should NOT be sanded. IS that truly accurate? Should the rubber be sanded? Again, my instructions say to do sand all surfaces, but I doubt the instructions are accounting for a rubber handle. Thoughts? Really don't want to mess this one up...

Is the handle made of plastic or is it a molded elastomer?

Thermoform plastics, such as TPR and PVC can be bonded with any cross linked adhesive formulated for plastomer material. No mechanical abrasion is required, simply scrub the surface with a harsh solvent in order to chemically swell, etch, and degrease it shortly before gluing. Methyl ethyl ketone is best. Both surfaces must be wiped.

Crossgluing a plastomer to an elastomer requires use of a halogenation primer.

HI Office.

It is made of molded Rubber.

That component will be molded EPDM.

For maximum longevity, the surface of the handle should be lightly sanded with 120 grit, then halogenated and bonded with PVC adhesive.

Without halogenation type primer, the longevity will be approximately 1 to 2 years before the bond will be rejected due to chemical incompatibility.

Thanks Office!

So scrub PVC with something like acetone but do not sand? And what type of material or chemical can I use as a halogenation? Thanks!

My glue came with 2 packages. I'll read the instructions but I assume it was to mix them to create the effect needed.
