Which adhesive works BEST on rubber? Round 2 (one WINNER)

In the end, cyanoacrylate (superglue) worked best! It's the only one that actually turned out as strong as the rubber itself, enough to tear it.

Rubber type adhesives dont bond well to most rubber substrates, in fact most types of adhesive dont bond well to most rubber substrates . That being said, anyone who is into gold prospecting knows that non gel type cyanoacrylates (ie; superglues ) bond tenaciously to most rubber substrates as they use it to glue sections of rubber sluice matting together and even though they are edge glued so the surface area is very small the substrate will usually tear before the glue joint fails . Also it should be noted that rubber sluice matts are subject to frequent short term submersion and a high degree of abrasion, even still the joints will often last for years without failing . Just my 2c worth

This was great, super nice to see the different results. Cheers!

Give automotive goop a try for just general rubber to rubber bonding. I fond it works very well. It's also black which is helpful when bonding rubber. Preparation is the most important step when trying to bond rubber. Make sure you strip the surface of any finish, quite often there is a layer of silicone on top. You can use naphtha gas or acetone to prep the surface. Make sure the surface is prepped for adhesion by roughing it up with a roughing tool from a bike tire patch kit or a coarse wire wheel. Sandpaper will contaminate the area. Spray again with acetone and let it flash off. For an easy to access product, try automotive goop. I find it works quite well. Otherwise you can go with something more specialized like a 2 part mix like sika bond R&B-210 which is a product for repairing conveyor belts.

Can you please provide the link to buy the best glue for JSL Super Glue Cyanoacrylate. I can not find it.

[Sharperthanu]

Super glue is what I need to glue rubber.

My go-to adhesive is lexel, which is a toluene solvent-based sealant. I put it in a mason jar and add extra toluene. The toluene seems to bite into most rubbers and plastics. This adhesive does take a while to cure but is very flexible and tough.

No offense but you always clean with acetone or lacquer thinner before adhering. Your test wasn't reliable.

Contact cement would've been my pick in this shootout. The caveat of reg. CA is its brittleness.

[JacobKnightRiderShop]

what about scratching up the rubber before adding the adhesives

[abrahamrwezaura]

Conclusion. Superglue is best for smooth surfaces. Other adhesives are for the rough surfaces, you have to roughen the surfaces first using sand paper for best result

[fredcdobbs]

Cyanoacrylate Super/Krazy glue is more forgiving & works better on unprepared surfaces because it's not as affected by surface contaminates.

[tarquineous]

What is the brand name of the construction adhesive?

[leedavis]

Inner tube repair glue works on rubber !

[Samlol_drrich]

Thank you for this video. Very helpful for me.

Let’s make a video starring all the wrong choices

[Bigshoots]

So. You didn't clean or prepare your surfaces before trying those other adhesives?

[Sharperthanu]

Silicone creates its' own "rubber" and hot glue creates its' own flexible plastic.Especially when you mix it with baking soda.

Jsl super glue is not available here, can you test e 6000, shoe goo, godzilla on rubber which will be best

[billsmith-mytl]

3m pr1500 or pr gel. It will NEVER fail. Specifically made for plastic and rubber (pr)

[jaycarter]

yaa it might be the winner but guaranteed if used in tire repair your tire will be flat the next day
