Bonding Polycarb to Polycarb and Trim Cap


Recommended Posts

Have to do a plug because I'm impressed with the results. I've never used Channel Bond I've only heard the name in the past and when I heard the name I thought it was a metal adhesive of some sort.

post-3-0-32378100-1335919999.jpg

So I did a quick demo/sample/test of bonding Poly-carb to Poly carb in a small 90 degree angle, and I bonded PLASCO trim cap to polycarb in a letter "L". I let it cure overnight and damn it's a strong bond. I can't bend the stuff to break the bond, I'm probably going to have to have a hammer or do something very violent to break it.

From what I understand Channel Bond is the equivalent of Weld-On 55 or 56 which is a two part system, where you need to buy the gun, the tips, the two small cartridges one of part A and B, and once you use it or activate it that's it, this seems costly. With Channel Bond it's a one part system, so you just pour it back if and when you're done, what I have is a huge Quart that will go a long way. Pretty Nice!

What I've discovered is Channel Bond is not a West Coast Product, in fact not many of heard of it very few have. Many though it was a metal bond too, same as I, my guess is it's because Weld-On and others are West Coast because of factory locations.


I'm sure all products and 1 or 2 part systems have their pro's and con's but...I'm impressed. So anyway, I just thought I'd post my thoughts of it.

Interesting - where's it from or who carries it. We do alot of t/c to poly, etc. Was it necessary to dry overnight - or that's how long it took you to try your break test? Oops, I see Transco on the label - so I would assume that anyone that carries Trancso---

It adheres pretty fast after they touch, it's pretty strong after 30 mins or so, should be good to go after 5-6 hours, but I let mine sit for 24 hours before unclampping. Anyone who sells Transco. I just starting messing with their Resin Bond too, which is like the Weld-On 4.

methelene chloride works good too. also bonds polycarb to polycarb. 5 gallons, under $100. pretty much a lifetime supply for me. Might not be legal in CA though.... :coffee1::laughing1:

Can you show a shot of the ingredients?

Ha, don't know if it's legal to have MC here but a lot of shops carry it in 5 Gal containers. But isn't that water thin?

The Channel Bond Is syrupy to give you time. On the ingredients I don't know but one part of it is MC from my understanding

I have been using both Channel Bond and Resin Bond for years. Do NOT use Resin Bond for Polycarb, it bonds fine but degrades over time Channel Bond is strictly for acrylic aplications. Also I see you have a blue tip on your syring bottle, try a pink tip they are bigger diamiter and the Channel Bond passes through it better. We unclamp letter faces within an hour of bonding but always let them sit over night before installing. The stucc is great but both will litterly evaporate from the can. We keep ours refrigerated lasts years that way.

Channel Bond can be used for Acrylic applications but it's formulated for Polycarbonate. Resin Bond is not formulated for Polycarbonate but specific for Acrylic applications.

On the applicator in the pic next to the CB, that wasn't used with CB but it was used with RB. Did some I-Beams with the RB with Acrylic and they tunred out nice and strong but haven't tried trim capping with it yet, I only had time to trim cap polycarb using CB. I used a 25 with the RB and a 49 with the CB

It is possibly just methylene chloride with a some polycarbonate dissolved in.

Ask for a material safety data sheet.

That will tell you the ingredients but not ratios.

Almost anything you do to polycarbonate other than cutting voids the warranty.

I hate working with polycarbonate and usually talk my clients into using impact modified acrylic.

Bonding dissimilar plastics is a bit like welding aluminium to steel.

It can be done but isn't really ideal long term.
