I'm an office administrator for a 140-person packaging and print company. I handle most of the supply purchasing—roughly $80,000 a year across a dozen vendors, and I report to both operations and finance. So when I compare adhesives, I'm not testing them in a lab. I'm comparing them on cost-per-completed-part, worker frustration, and rework rate.
Here's the thing: there's no single “best” adhesive. There's best for your materials, best for your timeline, and best for your budget. If somebody tells you one glue handles every job, you're dealing with a red flag, not a product recommendation.
Scenario A: Fabric, Craft, and Mixed-Material Bonding — e6000 Craft Adhesive
For fabric, leather, wood, glass, and general craft work, e6000 craft adhesive is the workhorse. It dries flexible, grips well, and handles odd material combos that make cyanoacrylate fail. We use it for packaging mockups, fabric prototypes, and attaching printed inserts to cardstock.
It's not perfect. E6000 has a solvent smell and needs time to cure. And if you apply it to certain foams or plastics without testing first, it can eat them. But for the right job, it's dependable.
Scenario B: Electronics, Small Repairs, and the B7000 Glue vs E6000 Question
The “b7000 glue vs e6000” debate usually comes up when someone needs to bond a small plastic housing or a phone screen. Both products are flexible, strong, and come in familiar red or blue tubes. They aren't twins, though. B7000 is thinner and behaves more like a controlled sealant. E6000 is thicker and better for larger surfaces.
I went back and forth on a project last year: a custom printed control panel shell for a trade show display. E6000 would have provided a tough bond on the enclosure's backing, but B7000 flowed into the narrow channel without squeezing out onto the printed surface. In that scenario, B7000 was the right call. On an earlier job, E6000 was right because we were bonding two large flat surfaces and needed a thick, flexible adhesive line.
Rule of thumb: Wide + flexible = E6000. Tight + precise + gap-filling = B7000.
Scenario C: Fast Repairs and the Question “Does Super Glue Melt?”
Super glue is fast. Simple. Done. It's a no-brainer for wood, metal, most ceramics, and some rubbers when you need a quick bond. But it has compatibility limits. When people ask “does super glue melt” what they really mean is: “it ruined this plastic part—why?” The plastic didn't actually melt like ice on a hot sidewalk. Cyanoacrylate can craze, fog, or crack certain plastics—polystyrene, polycarbonate, and ABS can be sensitive, especially if the adhesive gets trapped or you use too much.
I often compare that to people searching for the C8 Corvette Tremec manual. They type it because they've heard the C8 uses a Tremec gearbox and wonder if it's still a stick shift. The answer is no, not in the traditional sense: it's a Tremec dual-clutch automatic. Once you understand the mechanism, the original question changes. Same with super glue and plastic: the mechanism matters more than the word “melt.”
If the part is a soft plastic, foam, or a smooth polycarbonate housing, choose a flexible adhesive like E6000 or B7000 and test on a hidden area first. Super glue is for speed, not for fragile substrates.
Buying for Business: Value Over Price
From my perspective, the biggest mistake in purchasing isn't picking the wrong glue. It's picking by price alone. The lowest quote feels responsible, but it can be expensive.
I learned this the hard way. In 2023, we took a cheaper printed packaging quote because it saved us $180 on the order. The supplier switched to a budget adhesive for the box flaps, and 300 boxes failed when the boxes were stacked. Reprinting and expedited shipping cost $1,600. That's the kind of lesson you remember.
People think expensive suppliers deliver better quality. Actually, suppliers who solve your problem can charge more. The causation runs the other way. I'd argue the cheapest tube is a gamble, not a strategy.
Also, from one buyer to another: keep line items clean. Using a fuel credit card for business is fine when the transaction is actually fuel. It's not fine when you're paying for adhesives, printed materials, or other office supplies. The reward program won't help you when accounting is trying to reconcile a strange purchase.
Which Scenario Are You In?
Here's a simple way to decide:
- What are you bonding? Fabric, wood, leather, or mixed surfaces → e6000 craft adhesive.
- Electronics, small plastics, or precision channels → B7000.
- Quick fix on wood, metal, ceramic, or a non-sensitive plastic → super glue.
If you're still torn, buy one tube of each and test on scrap. It's way cheaper than redoing a production run. The best purchase decision comes from testing, not from the package claim.
There's something satisfying about a box that comes back looking the way it should. After the stress and the reprints, that's the payoff.
Trust me on this one.
Pricing note: As of January 2025, a typical 3.7 oz tube of E6000 runs about $5–$9, and B7000 usually runs $4–$8 at major craft retailers and online stores. Verify current pricing before ordering—prices change.
