Product Description
PERMABOND® 910 is a single-part, low-viscosity methyl cyanoacrylate adhesive developed for rapid bonding of close-fitting components. It is designed especially for metal surfaces and also bonds many plastics, rubbers and phenolic materials. The adhesive requires no mixing, fixtures in approximately 10–15 seconds on several tested substrates and reaches full strength after 24 hours at room temperature. Its low-viscosity liquid form supports controlled application into thin bondlines with a documented maximum gap fill of 0.15 mm.
Key features
- Rapid fixture: Reaches the documented 0.3 N/mm² handling-strength threshold in approximately 10–15 seconds on steel, Buna-N rubber and phenolic.
- Single-part application: Requires no mixing and cures at room temperature after assembly into a thin bondline.
- Low viscosity: A typical viscosity of 70–90 mPa·s at 25°C supports controlled dispensing on close-fitting parts.
- Strong metal bonding: Provides documented ISO 4587 shear strength on steel, aluminum, brass and stainless steel.
- Military specification approvals: Approved to MIL-A-46050C Type I Class 2 for existing designs and CID A-A-3097 Type I Class 2 for new designs.
Suitable for
- Close-fitting metal component assemblies
- Rapid bonding of selected plastics, rubbers and phenolic materials
- Production processes requiring fast fixture and minimal adhesive preparation

Additional Information
PERMABOND® 910
PERMABOND® 910 is a single-part, low-viscosity methyl cyanoacrylate adhesive designed primarily for rapid bonding of metal surfaces. It cures at room temperature after being pressed into a thin film between close-fitting components and also bonds many plastics, rubbers and phenolic materials.
Single-part methyl cyanoacrylate adhesive for rapid bonding of close-fitting components.
Uncured adhesive properties
The low-viscosity liquid is intended for accurately aligned, close-fitting parts. The viscosity value applies to the uncured adhesive at the specified temperature and does not independently establish wetting or gap-filling performance.
| Property | Typical value | Condition |
|---|---|---|
| Component | One | No mixing required |
| Chemical composition | Methyl cyanoacrylate | - |
| Appearance | Colorless liquid | - |
| Viscosity | 70–90 mPa·s | 25°C |
| Specific gravity | 1.1 | - |
All values are typical guideline data and are not guaranteed production specifications.
Fixture time, gap fill and full strength
Fixture or handling time is defined by the time required to achieve 0.3 N/mm² shear strength. It is not equivalent to full cure or final bonded-joint strength.
| Substrate | Typical handling time | Definition |
|---|---|---|
| Steel | 10–15 seconds | Time to 0.3 N/mm² shear strength |
| Buna-N rubber | 10–15 seconds | Time to 0.3 N/mm² shear strength |
| Phenolic | 10–15 seconds | Time to 0.3 N/mm² shear strength |
Temperature, humidity, substrate chemistry and joint gap can alter cure speed. Larger gaps and acidic surfaces may slow fixture development.
Surface preparation and bonding process
PERMABOND 910 cures rapidly after assembly, so surfaces should be prepared and components aligned before adhesive is dispensed. Apply only enough material to spread into a thin bondline.
Recommended visual: substrate cleaning, optional metal abrasion, controlled dispensing, immediate alignment, pressure and rapid fixture.
Slow-curing surfaces
Larger gaps and acidic surfaces can reduce cure speed. Permabond C Surface Activator or Permabond QFS 16 may be evaluated where accelerated curing is required.
Porous or difficult surfaces
An appropriate Permabond activator may be considered for porous or otherwise difficult substrates, subject to application testing.
Low-surface-energy polymers
Polypropylene, polyethylene, PTFE and silicone require Permabond Polyolefin Primer before bonding with the adhesive.
Storage and handling
Store PERMABOND 910 at 2–7°C. Before opening, allow the closed bottle to reach room temperature to prevent condensation inside the container, as moisture introduced during opening may reduce shelf life. Use appropriate industrial hygiene practices and consult the current regional safety documentation before handling.
Substrate-specific shear strength
The following ISO 4587 results apply to the stated substrates and test configuration. Bond strength can vary with substrate grade, surface preparation, joint gap and cure conditions.
| Substrate | Typical shear strength | Test or failure context |
|---|---|---|
| Steel | 23–29 N/mm² (3,300–4,200 psi) | ISO 4587 |
| Aluminum | 13–15 N/mm² (1,900–2,200 psi) | ISO 4587 |
| Brass | 21 N/mm² (3,000 psi) | ISO 4587 |
| Stainless steel | 21 N/mm² (3,000 psi) | ISO 4587 |
| Butyl rubber | Greater than 2 N/mm² | Substrate failure reported |
| Nitrile rubber | Greater than 4 N/mm² | Substrate failure reported |
| Phenolic | Greater than 10 N/mm² | Substrate failure reported |
| ABS | Greater than 9 N/mm² | Substrate failure reported |
| Acrylic | Greater than 14 N/mm² | Substrate failure reported |
| PVC | Greater than 6 N/mm² | Substrate failure reported |
| Polycarbonate | Greater than 6 N/mm² | Substrate failure reported |
A substrate-failure result indicates that the tested substrate failed before the adhesive joint under that test configuration. It does not establish a universal minimum adhesive strength.
Mechanical, thermal and electrical properties
These values describe cured adhesive or a specified laboratory test configuration. They should not be interpreted as universal bonded-assembly performance.
| Property | Typical value | Method or condition |
|---|---|---|
| Impact strength | 3–5 kJ/m² ((1.4-2.4 ft-lb/in²) | ASTM D950 |
| Dielectric constant | 2.5 | 10 kHz |
| Dielectric strength | 25 kV/mm | Typical cured material |
| Coefficient of thermal expansion | 90 × 10−6 mm/mm/°C | Typical cured material |
| Thermal conductivity | 0.1 W/(m·K) | Typical cured material |
| Hardness | 85 Shore D | ISO 868 |
Temperature and environmental guidance
The cured adhesive may be exposed down to approximately −55°C, depending on the bonded materials. It may also tolerate higher temperatures briefly during processes such as paint baking or wave soldering when the joint is not heavily stressed.
The product is not recommended for contact with strong oxidizing materials or polar solvents. Chemical exposure and temperature capability should be confirmed in the actual substrate system, joint geometry and load condition.
Rapid assembly of close-fitting components
PERMABOND 910 is most relevant where parts can be accurately aligned before dispensing and assembled rapidly into a thin bondline.
Metal component assembly
The adhesive was developed for bonding metal surfaces and has documented ISO 4587 strength on steel, aluminum, brass and stainless steel. Surface cleaning and oxide removal remain important to joint consistency.
Plastic and phenolic parts
Published test data support evaluation on ABS, acrylic, PVC, polycarbonate and phenolic. Actual performance depends on polymer grade, molded-surface condition and any release-agent residue.
Rubber component bonding
The adhesive provides documented substrate-failure results on butyl and nitrile rubber under the cited shear test. Rubber formulation, surface bloom and flexibility should be considered during application testing.
