Description
Permabond TA4610 Overview
Permabond TA4610 is a two-part, 1:1 toughened structural acrylic (MMA) adhesive that bonds untreated low surface energy plastics including polyethylene (HDPE, LDPE, UHMW), polypropylene and PTFE. No flame, corona, plasma or primer treatment is required before bonding.
TA4610 is the large-component grade in the TA4600 series. Fixture time runs 12 to 15 minutes with handling strength at 40 to 50 minutes, which gives an operator time to position and clamp a large or awkward assembly before the adhesive locks up. It carries the highest mixed viscosity in the series at 210,000 cP and contains microparticles that control bond line thickness and support gaps up to 1 mm.
TA4610 also bonds underwater and has published water resistance, which separates it from TA4605. Both parts are methacrylate based, solvent free, and non-hazardous for transport.
Which TA4600 Grade Do You Need?
All four grades bond the same difficult plastics. The choice comes down to how fast you need to fixture, how large the assembly is, and how much gap the joint has.
| Grade | Key Difference | Fixture Time | Full Cure | Mixed Viscosity | Max Gap | Sizes |
|---|---|---|---|---|---|---|
| TA4605 | Fastest fixture in the series | 5 to 10 minutes | 24 hours | 125,000 cP | 1 mm (0.04 in) | 50ml, 400ml, 20 kg bulk |
| TA4610 (this page) | Longer open time for large components, bonds underwater | 12 to 15 minutes | 48 hours | 210,000 cP | 1 mm (0.04 in) | 50ml, 400ml |
| TA4611 | No microbeads, for tight-fitting joints and thin bond lines | 10 to 16 minutes | 24 to 36 hours | 21,500 cP | 0.5 mm (0.02 in) | 25ml, 50ml, 400ml |
| TA4631 | No perceptible odor, no microbeads, bonds underwater | 12 to 18 minutes | 24 to 36 hours | 21,500 cP | 0.5 mm (0.02 in) | 25ml, 50ml, 400ml |
Choose TA4610 when the assembly is large enough that a 5 to 10 minute fixture window is too tight, when the joint has a measurable gap, or when the bond will see water. Drop to TA4605 if throughput matters more than working time. Move to TA4611 or TA4631 if the parts fit tightly and microparticles would hold the joint open. See the full low surface energy plastic bonding guide for substrate-by-substrate selection.

Nature of surface, surface preparation, glue line thickness, substrate thickness, pull speed, batch variation, cure time and temperature all affect shear strength measurement. Values are guideline figures, not a specification. TA4610 publishes mild steel and stainless steel figures, which makes it a better documented choice than TA4605 when the joint is plastic to steel.
Performance in Production
- Pot life of 5 to 8 minutes and fixture at 12 to 15 minutes give an operator real time to position a large part before the joint sets.
- Handling strength at 40 to 50 minutes means fixtures and clamps stay on longer than with TA4605. Plan bench space accordingly on a high-volume line.
- Part A is thixotropic at 200,000 to 500,000 mPa.s, the heaviest in the series. The bead holds position well on vertical and overhead joints and resists slumping on wide bond lines.
- That same viscosity makes 400ml cartridges hard work by hand. Pneumatic dispensing is worth it for continuous production.
- Microparticles hold a controlled bond line and support gaps up to 1 mm. For tight-fitting parts where any standoff is a problem, use TA4611 or TA4631 instead.
- Bonds underwater and holds up in wet service, which covers submerged repair and marine work that TA4605 does not.
- Full cure takes 48 hours, the longest in the series. Do not load a joint to full design strength before then.
- Adhesive squeezed outside a closed joint cures more slowly and may feel soft due to air contact. Material inside the joint cures solid.
- TA4610 can take brief high-temperature excursions such as paint baking and wave soldering provided the joint is not unduly stressed.
- Not recommended in contact with strong oxidizing materials. May affect some thermoplastics, so check substrate compatibility before production.
Common Applications
- Large HDPE, polypropylene and UHMW fabricated assemblies where a short fixture window is impractical
- Tank, liner, panel and duct bonding on polyolefin fabrication
- Marine pipe support bonding. A Permabond case study is available in the downloads tab
- Submerged and wet-service repair where the bond will see water
- Bonding polyolefins to mild steel, stainless steel, aluminium and e-coated metals
- Composite bonding on epoxy FRP, polyester GRP and carbon fibre
- Rubber bonding on EPDM, nitrile, neoprene and butyl rubbers
- Engineering plastic bonding on acetal (POM), PET-G, PET-P and PEEK
- Nylon, PMMA, EVA, TPO, PBT and polyurethane bonding
- Replacing mechanical fasteners or welded joints on large plastic assemblies
Surface Preparation
- Surfaces must be clean, dry and grease-free before bonding.
- Molded polyolefin parts often carry residual mold release. Wipe with isopropanol (IPA) and let it fully evaporate before applying adhesive.
- On metals, aluminium and copper alloys benefit from light abrasion with emery cloth to remove the oxide layer.
- No primer, flame, corona or plasma treatment is required on the polyolefin side. That is the point of the TA4600 series.
Directions for Use
- Confirm surfaces are clean, dry and grease-free.
- Apply a thin bead of adhesive pre-mixed through a static mixer nozzle.
- Assemble components and clamp.
- Maintain pressure until handling strength is achieved. Time varies with joint design and the surfaces being bonded.
- Allow 48 hours at 23°C for full cure before applying full design load.
Sizes and Matching Dispensing Equipment
TA4610 cartridges need a matching 1:1 mixer and gun. Ordering the wrong mixer is the most common reason a first trial fails, so use this table to match the package to the hardware.
| Package | Full Case Quantity | Static Mixer | Dispensing Gun |
|---|---|---|---|
| 50ml Cartridge | 10 | MBQ 05-16L | Chem-Set PAK-50 with the 1:1 / 2:1 plunger |
| 400ml Cartridge | 6 | MFQ 08-24T | Albion B26T400 manual, or DP2X 400 pneumatic |
Order single cartridges or full cases, whatever the job needs. Bulk packaging is available on request. If you need a 25ml cartridge, look at TA4611 or TA4631, which are offered in 25ml and dispense by hand syringe with no gun required. Because TA4610 runs at 210,000 cP mixed, the DP2X 400 pneumatic gun is the better call for any shop running 400ml cartridges all shift.
Storage and Handling
| Format | Storage Temperature |
|---|---|
| Cartridges | 5 to 25°C (41 to 77°F) |
| Bulk | 2 to 7°C (35 to 45°F) |
Bulk material requires refrigerated storage. The product may separate slightly in storage. Invert the container to re-disperse before use. For professional and industrial use only.
Frequently Asked Questions
Do I need to flame, corona or plasma treat the plastic first?
No. The TA4600 series was developed specifically to bond untreated polyolefin surfaces. No primer or pre-treatment is required. Surfaces still need to be clean, dry and grease-free, and molded parts should be wiped with IPA to remove mold release.
What is the difference between TA4610 and TA4605?
Working time and water. TA4610 fixtures in 12 to 15 minutes with handling strength at 40 to 50 minutes, so there is time to position a large assembly. TA4605 fixtures in 5 to 10 minutes and reaches working strength faster, which suits throughput. TA4610 also bonds underwater and publishes water resistance. TA4605 does not.
Can TA4610 bond underwater?
Yes. Bonding underwater and water resistance are both published features of TA4610. Surfaces still need to be free of grease and loose contamination.
How long until I can load the joint?
Handling strength comes at 40 to 50 minutes and working strength at 6 to 8 hours. Full cure is 48 hours at 23°C. Hold off on full design load until then.
Will TA4610 bond PTFE?
Yes, at 2 N/mm² (290 psi) shear with substrate failure observed. That is a real bond on a material that is non-stick by design, and higher than TA4605 at 1.5 N/mm².
Does TA4610 bond rubber?
Yes. The TA4600 series bonds EPDM, nitrile, neoprene and butyl rubbers. EPDM contains polypropylene, which is why the polyolefin chemistry works on it. It does not bond silicone rubber.
What quantity do I have to order?
Whatever you need. There is no order minimum on any TA4600 series item. Buy a single cartridge for a trial or full cases for production.
Is TA4610 hazardous to ship?
No. The TA4600 series is non-hazardous for transport, which simplifies shipping and storage compared with solvent-based alternatives. TA4610 is solvent free.
