Permabond CA007370016Z0101, 737 Black Magic 1 Pound Bottle
Permabond CA007370016Z0101, 737 Black Magic 1 Pound Bottle
Permabond 737 Black Magic is a black, toughened cyanoacrylate adhesive with flexibility and improved impact and peel strength. SKU CA007370016Z0101 supplies one 1-pound bottle, not the case of smaller bottles. It bonds rapidly to compatible plastics, rubbers, aluminum and steel, including zinc-plated and uncoated steel. Its 2,000–4,000 cP viscosity and gap capability up to 0.5 mm suit joints needing a thicker, toughened instant adhesive.
Best Uses / Applications
Consider 737 for assembly joints requiring impact and peel resistance, rubber-to-metal bonding, plastic assembly and dark surfaces where a black bond line is appropriate. The larger individual bottle is an option for operations regularly using this grade. Validate substrates, dispensing method, joint design and service conditions before production. This is not a clear adhesive.

Handling times are measured at 0.3 N/mm² shear strength and are not full cure. Temperature, humidity, surfaces and gap affect cure. Strength results vary with preparation and gap; substrate failure means the tested material failed. TDS values provide guidance rather than guaranteed results for every application.
Package and Grade Comparison
| Selection factor | This listing / grade | Alternative |
|---|---|---|
| Package | CA007370016Z0101: one 1-pound bottle of 737 | CA007370001Z0101: ten 1-ounce bottles of the same 737 grade |
| 737 | Black; 2,000–4,000 cP; maximum gap 0.5 mm | Toughened formulation with impact and peel resistance |
| 268 | Colorless; 1,200–2,400 cP; maximum gap 0.43 mm | Increased gap capability, passivated metals and plastics such as polyacetals |
| 200 | Colorless; 1,500 cP; maximum gap 0.38 mm | Wire tacking and component bonding |
Viscosities are measured at 25°C. Choose according to bond-line appearance, flow, joint requirements and substrate testing, not gap size alone.
Surface Preparation and Directions for Use
Surfaces should be clean, dry and grease-free. Select a suitable degreasing solvent compatible with the substrate. Aluminum, copper and their alloys may benefit from light abrasion to remove surface oxide.
- Shake the bottle before use.
- Apply adhesive sparingly to one surface.
- Bring components together quickly and correctly aligned.
- Apply sufficient pressure to spread 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.
Difficult or porous surfaces may need a Permabond activator. Larger gaps and acidic surfaces can slow cure; CSA or QFS 16 are identified in the TDS as options to address this. Prime polypropylene, polyethylene, PTFE and silicone first with Permabond Polyolefin Primer (POP).
Manufacturer Application Videos
These general manufacturer guidance videos are referenced in the 737 TDS; they are not 737-specific demonstrations. Follow the written 737 instructions, including shaking the bottle before use, and review the TDS and SDS.
Storage and Handling
Store at 2–7°C (35–45°F). Allow adhesive to reach room temperature before opening 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 one bottle or a case?
SKU CA007370016Z0101 contains one 1-pound bottle of Permabond 737 Black Magic. The case of ten 1-ounce bottles is a separate SKU.
Is the adhesive the same as the smaller 737 bottles?
The stated grade is the same Permabond 737. Package size and quantity differ.
Is 737 clear, and why choose it?
737 is black, not clear. The manufacturer highlights flexibility and improved impact and peel strength. Select it where a black bond line is acceptable and validate the actual joint.
How fast does it cure?
Typical handling times are 15–20 seconds on steel, 30–35 seconds on aluminum, 10–15 seconds on Buna N rubber and 5–10 seconds on phenolic. Full strength takes 24 hours.
What gap can it fill, and should it be shaken?
The maximum specified gap fill is 0.5 mm (0.02 in). Yes, the 737 TDS explicitly instructs users to shake the bottle before use.
How should it be stored, and when is primer needed?
Store at 2–7°C and bring adhesive to room temperature before opening. Prime polypropylene, polyethylene, PTFE and silicone first with Permabond POP as directed by the TDS. Difficult or porous surfaces may require an activator.
