Permabond TA46XX Polyolefin Bonding Adhesives

Permabond TA4600 series structural acrylic adhesives in 25ml, 50ml and 400ml dual cartridges with static mixers

Adhesives for HDPE, Polypropylene, UHMW & PTFE

Bonding slick, waxy low surface energy plastics has historically meant flame, corona or plasma pre-treatment. The Permabond TA4600 series removes that step. Four grades bond untreated polypropylene, polyethylene (HDPE, LDPE, UHMW) and PTFE with no primer and no surface treatment, and they bond those plastics to steel, aluminium and composites.

Pick your grade below. All four are stocked, there is no order minimum, and every cartridge ships with a static mixer. Switching from 3M Scotch-Weld DP8010? See the DP8010 alternative notes below.

Shear Strength by Substrate

Grade	Polypropylene	HDPE	Mild Steel	Stainless	PTFE
TA4605	>1200 psi*	2175 psi	Not published	Not published	220 psi
TA4610	1200 psi*	2175 psi	Not published	725 psi	290 psi*
TA4611	>1160 psi*	1160 psi	1595 psi	1305 psi	>290 psi*
TA4631	>1160 psi*	1160 psi	2030 psi	870 psi	>290 psi* (mild steel to PTFE)

All grades are 1:1 mix ratio, cure at room temperature and are non-hazardous for transport. An asterisk indicates the substrate failed before the bond line. Values are guideline figures from Permabond data sheets, not a specification.

Temperature: the data sheets list -55°C as the minimum exposure for the cured adhesive, depending on the materials bonded. Joint strength falls as temperature rises, and brief high-temperature excursions such as paint baking are acceptable only if the joint is not unduly stressed. Test at your operating temperature before production.

Alternative to 3M Scotch-Weld DP8010 for Polyolefin Bonding

Yes, the Permabond TA4600 series is a set of two-part acrylic adhesives that bond untreated polypropylene and polyethylene with no primer, which is the job 3M Scotch-Weld DP8010 is used for. We call them alternatives, not equivalents. Test on your own parts before you change a production process.

Mix ratio is the first thing to check

The TA4600 grades mix 1:1. 3M lists DP8010 at 10:1 by volume, so a gun set up with a 10:1 plunger will not dispense a TA4600 cartridge correctly. The plunger sets the ratio. Each TA4600 cartridge ships with its static mixer. The 25ml TA4611 and TA4631 syringes need no gun, which makes them the cheapest trial.

Check working time against your line

Pot life at 23°C (2g + 2g) differs by grade:

TA4605: 2 to 4 minutes
TA4610: 5 to 8 minutes
TA4611: 4 to 6 minutes
TA4631: 4 to 6 minutes

Choose between the four on joint design: gap, fixture speed, flow and odor. The grade table above covers that.

Is any TA4600 grade a direct replacement for DP8010?

We do not call any of them a direct replacement. Mix ratio, working time and cure profile differ, so run a trial on your parts. Call us with your plastics and your current cycle time and we will point you to the grade to try first.

Can I use my 3M EPX gun?

Yes, for the 50ml cartridges. Swap the 10:1 plunger for a 1:1 plunger and the TA4600 cartridges run in your EPX gun. If you would rather leave the EPX gun as it is, the Chem-Set PAK-50 (CCH50G-1-1/2-1) ships with the 1:1/2:1 plunger. For 400ml cartridges, see the guns in the dispensing table below.

What You Need to Dispense It

Every cartridge ships with one static mixer. Order spares separately, since adhesive cures inside the mixer and each dispensing stop needs a fresh nozzle. Ordering the wrong mixer is the most common reason a first trial fails.

Package	Static Mixer	Dispensing Gun
25ml (TA4611, TA4631)	MBQ 05-16L	None. Hand syringe format
50ml (all grades)	MBQ 05-16L	Chem-Set PAK-50 with 1:1 / 2:1 plunger
400ml (all grades)	MFQ 08-24T	Albion B26T400 manual, or DP2X 400 pneumatic
20 kg bulk (TA4605)	Meter-mix equipment	Automated dispensing. Call for specification

The 25ml is the simplest way to run a first trial. It needs no gun at all, so you can order one cartridge and be bonding the same day.

Polyolefin Bonding FAQ

Do I really not need to flame or plasma treat first?

Correct. No primer or pre-treatment on the polyolefin. Surfaces still need to be clean, dry and grease-free, and molded parts should get an IPA wipe to remove mold release.

Which grade should I start with?

If the joint has a gap and you want speed, TA4605. Large or awkward assembly, TA4610. Parts that seat tight, TA4611. Odor in the work area or water exposure, TA4631. If you are unsure, the 25ml TA4611 or TA4631 syringe is the cheapest way to find out, since it needs no gun.

What does no micro beads actually change?

TA4605 and TA4610 contain microparticles that hold a minimum bond line around 1 mm. Useful for a controlled gap, a problem when parts are meant to seat tight. TA4611 and TA4631 have none, so parts close as designed, and maximum gap drops to 0.5 mm as a result.

Which grade is strongest on metal?

TA4631 at 2030 psi on mild steel, the highest published figure in the series. TA4611 leads on stainless at 1305 psi. TA4605 publishes no steel values at all.

Can any of these bond underwater?

TA4610 and TA4631 both list underwater bonding and water resistance as published features. TA4605 and TA4611 do not list it.

Will they bond PTFE?

Yes, though PTFE is non-stick by design so the figures are modest. TA4610 and TA4611 publish 290 psi or better on PTFE with substrate failure observed. TA4631 publishes mild steel to PTFE at over 290 psi with substrate failure. TA4605 is lowest at 220 psi.

Is there an order minimum?

No. Order a single cartridge for a trial or full cases for production, whatever the job needs.

+What These Adhesives Bond

The TA4600 series was built for polyolefins, and its range is wider than most buyers expect. Published shear data differs by grade, so check the grade page for your substrate.

Low surface energy plastics: polypropylene, polyethylene, HDPE, LDPE, UHMW, PTFE
Engineering plastics: nylon, PMMA, EVA, TPO, PBT, polyurethane, ABS, PVC, polycarbonate, PET-G, PET-P, acetal and PEEK. Published shear data for nylon (PA6), ABS, PVC and polycarbonate is on TA4605 and TA4610. PET-G and PET-P data is on TA4610 and TA4631. Acetal and PEEK data is on TA4631
Metals: mild steel, stainless steel, aluminium, e-coated metals
Composites: carbon fibre, epoxy FRP, polyester GRP
Rubbers: EPDM, nitrile, neoprene and butyl. Published EPDM data is on TA4605 and TA4610
Other: wood and concrete

+Surface Preparation and How to Apply

Surfaces must be clean, dry and grease-free. That is the whole prep on the plastic side.
Molded polyolefin parts often carry residual mold release. Wipe with isopropanol and let it fully evaporate before bonding.
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 needed on the polyolefin. That is the point of this range.

Applying it

Apply a thin bead pre-mixed through the static mixer nozzle.
Assemble and clamp.
Hold pressure until handling strength is reached. Time varies with joint design and substrates.
Allow the grade’s full cure time before applying full design load.
Adhesive squeezed outside a closed joint cures more slowly and may feel soft from air contact. Material inside the joint cures solid.

+Why HDPE and Polypropylene Are So Hard to Bond

HDPE, polypropylene and PTFE have extremely low surface energy. Their slick, chemically resistant surfaces make it nearly impossible for a standard adhesive to wet out. Poor wetting means the adhesive sits on top of the plastic instead of biting into it, and the joint fails easily.

The traditional fix is to raise the plastic’s surface energy artificially with flame, corona or plasma treatment, or with a primer. All of that costs equipment, floor space and process time. The TA4600 series chemistry wets out and grips untreated polyolefin directly, which is why the plastic often tears before the bond does.

Left: high surface energy, good wetting. Right: low surface energy, poor wetting.
