Permabond CA002680016Z0101, 268 1 Pound Bottle
Permabond CA002680016Z0101, 268 1 Pound Bottle
Permabond 268 is a medium-high viscosity ethyl cyanoacrylate adhesive for rapid bonding of compatible metals, ceramics, plastics and elastomers. SKU CA002680016Z0101 supplies one 1-pound bottle of the same 268 grade offered in the smaller-bottle package. Its 1,200–2,400 cP viscosity and maximum specified gap fill of 0.43 mm suit applications requiring increased gap capability compared with conventional cyanoacrylates.
Best Uses / Applications
Consider Permabond 268 for bonding rough surfaces, passivated metals, rubber components, ceramics and plastics. The manufacturer specifically highlights difficult-to-bond plastics such as polyacetals. The larger individual bottle is an option for assembly operations using this grade regularly. Validate the actual substrates, dispensing method, joint gap and service conditions before production use.

Handling time is measured at 0.3 N/mm² shear strength, not full cure. Cure speed depends on temperature, humidity, surfaces and gap. Strength results vary with preparation and joint gap. Substrate failure means the tested material failed, not that every joint will achieve the same result. TDS data are typical guidance rather than an application-specific specification.
Package and Adhesive Comparison
| Selection factor | This listing / grade | Alternative |
|---|---|---|
| Package | CA002680016Z0101: one 1-pound bottle of 268 | CA002680001Z0101: ten 1-ounce bottles of the same 268 grade |
| 268 viscosity and gap | 1,200–2,400 cP; maximum gap 0.43 mm | 200: 1,500 cP; maximum gap 0.38 mm |
| Lower-viscosity option | 268 is intended for increased gap capability and a range of difficult surfaces. | 105: 30–50 cP; maximum gap 0.1 mm, suited to tight-fitting joints and wicking applications |
| Application emphasis | 268: rough surfaces, passivated metals and plastics such as polyacetals | 200: wire tacking and component bonding |
Choose the package for your workflow and the grade for actual flow, gap and substrate requirements. “Large gap” is relative to conventional cyanoacrylates; do not exceed the 0.43 mm maximum specified for 268.
Surface Preparation and Directions
Surfaces should be clean, dry and grease-free. Select a suitable degreasing solvent compatible with the substrates. Aluminum, copper and their alloys may benefit from light abrasion to remove surface oxide.
- Apply adhesive sparingly to one surface.
- Bring parts together quickly and correctly aligned.
- Apply enough pressure to spread the adhesive into a thin film.
- Do not disturb or realign until sufficient handling strength develops.
- Allow 24 hours for full strength before evaluating final performance.
For difficult or porous surfaces, the manufacturer recommends a Permabond activator. Larger gaps and acidic surfaces can slow cure; the TDS identifies CSA or QFS 16 as options to address this. Prime polypropylene, polyethylene, PTFE and silicone first with Permabond Polyolefin Primer (POP).
Storage and Handling
Store at 2–7°C (35–45°F). Allow adhesive to reach room temperature before opening the bottle to prevent internal condensation that can reduce shelf life. The TDS does not recommend contact with strong oxidizing materials or polar solvents. Review the Safety Datasheet before use. For professional or industrial use only; keep out of reach of children.

Frequently Asked Questions
Is this a single bottle or a case?
CA002680016Z0101 contains one 1-pound bottle of Permabond 268. The case of ten 1-ounce bottles is a separate listing.
Is the adhesive different from the smaller 268 bottles?
The stated grade is the same Permabond 268. Package size and quantity differ.
What surfaces is 268 intended for?
The manufacturer identifies metals, ceramics, plastics and elastomers, including passivated metals and difficult plastics such as polyacetals. Test your actual material combination before production.
How large a gap can it fill?
The maximum specified gap is 0.43 mm (0.017 in). Do not interpret increased gap capability as unlimited gap filling.
Does 5–10 seconds mean full cure?
No. That is the typical handling time on steel, Buna N rubber and phenolic, measured at 0.3 N/mm² shear strength. Full strength takes 24 hours.
How should the bottle be stored, and is primer needed?
Store at 2–7°C and bring the adhesive to room temperature before opening to prevent internal condensation. For polypropylene, polyethylene, PTFE and silicone, the TDS directs users to prime first with Permabond POP; difficult or porous surfaces may need an activator.
