Permabond CA007370001Z0101, 737 Black Magic, 1 Ounce Bottle, Case of 10
Permabond CA007370001Z0101, 737 Black Magic, 1 Ounce Bottle, Case of 10
Permabond 737 Black Magic is a black, toughened cyanoacrylate adhesive with improved impact and peel strength and flexibility. SKU CA007370001Z0101 contains ten 1-ounce bottles per case. It bonds rapidly to compatible plastics, rubbers, aluminum and steel, including zinc-plated and uncoated steel. Its dark color suits dark surfaces, while its 2,000–4,000 cP viscosity supports gap filling up to 0.5 mm.
Best Uses / Applications
Consider 737 for assembly joints requiring a toughened instant adhesive with impact and peel resistance, rubber-to-metal bonding, plastic assembly and dark-surface applications where a black bond line is appropriate. Validate substrate compatibility, joint design and operating conditions before production. It is not a clear adhesive.
Key Features

Handling time is measured at 0.3 N/mm² shear strength and is not full cure. Temperature, humidity, substrate and joint gap affect cure. Strength varies with preparation and gap; substrate failure means the tested material failed. TDS values are guidance, not guaranteed results for every application.
Adhesive Selection Comparison
| Grade | Appearance / viscosity | Maximum gap | Selection emphasis |
|---|---|---|---|
| 737 | Black; 2,000–4,000 cP | 0.5 mm | Toughened, flexible formulation with impact and peel resistance |
| 268 | Colorless; 1,200–2,400 cP | 0.43 mm | Increased gap capability, passivated metals and plastics such as polyacetals |
| 200 | Colorless; 1,500 cP | 0.38 mm | Wire tacking and component bonding |
Viscosities are measured at 25°C. Select based on bond-line appearance, flow, joint design and substrate testing, not gap size alone.
Surface Preparation and Directions for Use
Surfaces should be clean, dry and grease-free. Use a suitable degreasing solvent compatible with the substrate. Aluminum, copper and their alloys may benefit from light abrasion to remove oxide layers.
- 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 require 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).
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 avoid internal condensation that can reduce shelf life. The TDS does not recommend contact with strong oxidizing materials or polar solvents. For professional or industrial use only; keep out of reach of children. Review the Safety Datasheet before use.
Frequently Asked Questions
What does this SKU include?
CA007370001Z0101 contains ten 1-ounce bottles of Permabond 737 Black Magic, sold as a case.
Is 737 clear or black?
737 is black. Choose it only where a dark bond line is acceptable; it is not the colorless formulation used in grades such as 200 or 268.
Why choose a toughened cyanoacrylate?
The manufacturer highlights improved impact and peel strength with flexibility. Test the joint under its actual load and service conditions to determine suitability.
How quickly can bonded parts be handled?
Typical 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. These are handling times, not full cure; full strength takes 24 hours.
What is the maximum gap, and does the bottle need shaking?
The specified maximum gap is 0.5 mm (0.02 in). Yes, the 737 TDS explicitly instructs users to shake the bottle before use.
Is primer required, and how should bottles be stored?
The TDS directs users to prime polypropylene, polyethylene, PTFE and silicone with Permabond POP. Store at 2–7°C and bring adhesive to room temperature before opening to prevent condensation inside the bottle.
