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.

      Apparently Jewelite is out of their Gold Trim Cap until July / August, so we've been getting a lot of calls from large Sign Shops for orders of Plasco's 1" Gold to complete a rather large Sign Program.
       
      So I dug out a Jewelite Sample of Gold, compared to Plasco's Gold Channel Letter Trim Cap.  
       

       

       
      In the comparison, Plasco has just a more nicer gold color, Jewelite looks more of a washed out metal coloring with a little gold in it, IMO.  
       
      If you're looking to see the Gold difference between the two to substitute, I think using Plasco 1" Gold Trim Cap will make those signs look so much better.

      Some notes I'd like to add about this product.

      Some may have used this product in the past and some may have never had a chance. This product disappeared from suppliers right after 9/11 from what I understand there were Customs issues that made it too costly to bring in.

      IF you remember this product from long ago, you will be glad it's back (just like the reaction I've gotten to all who have purchased from me).

      IF you have never used it, your fabricators will love you for using it, it's MUCH MUCH easier to work with and notch, you won't get those splits you sometimes get on corners.
      My other understanding is that this product was mainly distributed on the west coast, so not many on the east coast have ever tried it. My advice is try it, believe me YOU will LOVE it!

      Before 9/11 I used PLASCO and the Silvatrim Trimcaps. I still have signs up 16+ years and this trim cap is still up, it's very durable.
       
       
       
      PLASCO Trim for Polycarbonate Channel Letter Faces
      Plasco is an excellent channel letter trim cap to be used to fabricated polycarbonate / Lexan channel letter faces. We also stock Channel Bond, the 1 part system which makes it easy for bonding Plasco Trim to Polycarbonate. You can also find Channel Bond here
       
      PLASCO VS JEWELITE
      In another thread I was asking why anyone east of Colorado "WHY" they mainly buy 1" Jewlite and not 3/4" Jewelite for 24" Channel Letters and smaller.
       
      The reason seems to be is that when you use 1" Jewelite with a standard 3/16" channel letter face the 1" Jewelite gives you more clearance because the arrow extrusion protrudes more than 1/4" from the face giving you less mechanical fastening room. Make sense but 1" is very tough to notch, bend and get in small letter centers too because of that arrow extrusion.
       
      I was always use to Plasco Trim Cap in my years of the sign industry, NOT Jewelite because on the West Coast Plasco was stocked more than Jewelite before 9/11. So after this "clearance" point was brought up I did some quick measuring because I had a east coast client buy Plasco 1" to match up with his regular use of 1" Jewelite. Then shortly after receiving his order with 3/4" samples he soon after starting ordering 3/4". I asked him why the change in smaller trim. He said the change was because the 3/4" Plasco trim gave him the same fastening clearance that he got buying 1" Jewelite. He went from paying about $70.00 per roll to $44.75 saving $32.15
       
      I've attached some images to show you that you can use 3/4" Plasco Trim Cap that will give you the same clearance as 1" Jewelite IF clearance is important to you.
       
      Plasco vs. Jewelite - Here we display the channel letter baseline along with the clearance you get using 3/4" & 1" Plasco / Jewelite Trim Caps

       
      1" Jewelite clearance

       
      1" Plasco - More mechanical clearance than 1" Jewelite

       
      3/4" Plasco - Just about the same mechanical clearance as using 1" Jewelite

       
      3/4" Jewelite - Less mechanical clearance than 3/4" Plasco

       
      1" Jewelite - Arrow extrusion protrusion more than 1/4" past the channel letter face.

      Like everywhere else if you're very fortunate to be busy during this shut down, some business's are still willing to upgrade their branding in these slow depressing times
       
      We removed some outdated retail signage and upgraded them to their current look.
       
      I know, this is normally just an average channel letter sign....*Yawn*......but what's unique is the lighting system that powers it at night.
       
      The Illumination?
       
      BrightON II 24v constant current NOT constant voltage ....LEDs instead of the industry typical 12v LEDs for half the amperage across the wire and components which translates to less heat, resistance, and in return a MUCH better system for dependability.  Not even to mention just how much light for very little power you get from the super high efficient BrightON II Chips with the added 175˙ high efficiency optics.  Another advantage of 24V is the typical single channel power supplies are 96W, which means you can et LOTS of LED modules on a single power supply (less parts, less problems) which leads me to the next part...
       
      The system doesn't stop at the LEDs, it continues with France Lighting Solutions "True Power" LED Power Supplies.  The Electric Sign industries unique and sole 100% load Power Supplies, no not 85%, not 80%.....100%.  5 year Labor / 5 Year Parts.   If you've been in this industry long enough I don't even need to mention what "France" products mean....it mean Longevity & Dependability...just the BrightON II LEDs

      The Night Finished Look.
       
      For typical 5" deep return channel letters with front illumination light output measured right on the face for decent or as most LED MFG's like to say..."usable light"... if you have a light meter on hand ....."usable light" is right around 150 - 165 Foot Candles....that's just your typical even lighting number.  
       
      The BrightON II at full stretch already exceeds that and with fewer modules compared to competitors using higher powered LED modules.  This set right here gave us an average of 213 Foot Candles right on the face despite the light loss coming out of the rear.  Brighton LEDs are "Competitive Light"...NOT "Usable Light"
       

       
       
      In the end?  
       
      The client letting me know that they are VERY happy and that the sign looks AWESOME.
       
      These are the types of signs you flash to potential clients....Bright, Dependable, & Happy Reviews by Happy Customers.  If this sign was in a shopping center the light output alone would stand out, and far above other competing signs.

      What's just as good if not better than our Channel Letter trim Cap?
       

       
      Our fresh batch of Syndicate Bootleg Brewing "K-Liscious Summer Sunset Ale", that's what!  It goes perfect with Trim Capping, it gives your finger tips a cool buzz feeling while saving the taste of hoppy goodness!
       
      By the way, I STILL don't get why most of you buy 1" Jewelite or 1" Plasco trim Cap for your average size letters.  3/4" PLASCO has the same mechanical clearance as 1" Jewelite, and again MUCH easier to work with without having to worry about bending that Jewelite arrow trim around tight corners and bends for small letter faces.
       
      Check this out, see.....same mechanical clearance!
       
       

       
      So why spend the extra money on 1" Jewelite???
    • By Erik Sine
      To update everyone of our new stock and colors we now have a darker blue which matches pretty well with Avery's Dark Blue Translucent 8500 Vinyl series 007.
      We also have a real Duranotic Bronze to match most coated pre-fab Aluminum coils.
      Finally we have an Orange.
       
      These can be ordered from our store http://www.thesignsyndicate.com/forums/index.php?/store/category/10-trim-cap-plastic-adhesives/
