Permabond TA04550K050C0101, TA4550 50ml, Multi-Purpose Nylon-Bonding Adhesive, Case of 10
Permabond TA4550 is a two-part, 2:1 toughened acrylic structural adhesive developed for nylon/polyamide bonding without a primer or additional treatment such as plasma. It also bonds selected plastics, metals and composites, making it a candidate for dissimilar-material assemblies. Its thixotropic, non-slumping consistency supports controlled bead placement, including vertical applications.
SKU TA04550K050C0101: 50 ml cartridge kits, supplied as a case of 10. The formulation is low odor and cures at room temperature. Clean, dry, grease-free surfaces are still required: primer-free does not mean cleaning-free. Test the exact substrate grade and assembly before production release.
Best Uses / Applications
- Nylon/polyamide assembly: evaluate PA6, PA6.6 and PA12 applications described by Permabond using representative production parts.
- Dissimilar-material bonding: assess nylon-to-metal, plastic-to-metal and composite assemblies against the actual joint geometry and service conditions.
- Impact- and vibration-exposed assemblies: the toughened formulation provides a starting point for testing these requirements, not a guarantee for every joint.
- Controlled dispensing and vertical bonding: use the non-slumping consistency where bead placement matters; validate the mixer, bond-line thickness and assembly timing.
- Industrial component assembly: evaluate fixtures and handling sequence against the short pot life and the separate fixture, working-strength and full-cure milestones.
Key Features
- Two-part, 2:1 low-odor toughened acrylic.
- Developed for nylon bonding without primers or additional surface treatment such as plasma.
- Thixotropic, non-slumping consistency for flow control.
- Room-temperature cure with typical 3-minute pot life and 5–6-minute fixture time at 23°C.
- Typical working strength in 2 hours and full cure in 24 hours at 23°C.
- Manufacturer-reported maximum gap fill of 5 mm.

Technical values are manufacturer-reported typical data, not guaranteed specifications for every assembly. Joint design, surface condition, substrate grade, bond-line thickness and cure conditions affect results. Fixture time is not full cure.
Surface Preparation and Dispensing
- Prepare clean, dry, grease-free surfaces. The manufacturer advises wiping away possible mold-release residue with IPA and allowing the solvent to evaporate fully. Confirm solvent compatibility with the substrate.
- For metals such as aluminum, copper and its alloys, the manufacturer notes that light abrasion may help remove the oxide layer.
- Dispense a thin bead pre-mixed through an appropriate static mixer using the specified 2:1 system. Confirm cartridge, dispenser and mixer compatibility.
- Assemble and clamp the parts. Maintain pressure until sufficient handling strength develops for the actual joint.
- Allow the specified full-cure period before evaluating final performance. Exposed excess adhesive may cure more slowly and feel soft because of air contact.
Do not assume compatibility with every thermoplastic or chemical exposure. The technical sheet cautions against strong oxidizing materials and requires compatibility checks for thermoplastics. Follow the current safety data sheet for handling instructions.
Selection Comparison
| Selection question | How to evaluate TA4550 |
|---|---|
| Bonding nylon or a nylon-to-metal joint | TA4550 is developed for nylon/polyamide bonding. Validate the actual resin grade, surface condition and joint. |
| Bonding low-surface-energy PE or PP | Permabond identifies TA4611 as specializing in these plastics. Do not assume TA4550's nylon capability makes the grades interchangeable. |
| Needing more assembly time | Evaluate the 3-minute pot life against dispensing and alignment needs. Compare a longer-working-time grade if the process requires it. |
| Needing immediate final strength | Fixture time is an early milestone. Typical working strength takes 2 hours and full cure takes 24 hours at 23°C. |
| Bonding a vertical feature | Thixotropic behavior supports bead control, but validate placement and fixturing on the actual assembly. |
Frequently Asked Questions
Which nylons can TA4550 bond?
Permabond describes applications with nylon grades including PA6, PA6.6 and PA12. Fillers, additives, moisture and surface condition can affect the result. Test representative production parts rather than treating all nylon formulations as equivalent.
Does primer-free bonding mean no preparation is needed?
No. TA4550 was developed for nylon bonding without primers or additional treatment such as plasma, but the technical sheet still requires clean, dry, grease-free surfaces. Mold-release residue must be addressed, and some metals may benefit from abrasion.
What is the mix ratio?
The technical sheet specifies a 2:1 ratio of use. Use compatible dispensing equipment and a suitable static mixer, and follow the manufacturer's dispensing directions. Do not assume that any dual-cartridge gun or mixer will fit.
How fast does it cure?
At 23°C, typical pot life is 3 minutes for 10 g mixed, fixture time is 5–6 minutes, working strength is reached in 2 hours and full cure in 24 hours. These are different milestones. Temperature and assembly conditions affect cure behavior.
Can it bond dissimilar materials?
Yes, it is a candidate for selected combinations of nylon, other plastics, metals and composites. Qualification still needs to account for surface condition, joint movement, service exposures and the actual substrate grades.
Why can exposed excess adhesive feel softer than the bond?
The manufacturer notes that material outside a closed joint can cure more slowly because of air contact. This is not a reason to bypass the specified cure or assembly tests.
What quantity does this listing include?
This SKU is a case of 10 × 50 ml cartridge kits. Confirm dispensing accessories separately rather than assuming a particular gun or mixer is included.
