PT326 20min Rigid Polyurethane Adhesive

PT326 is a two-part, rigid cure, engineering-grade polyurethane (PU) structural adhesive which offers excellent bond strength to a wide variety of substrates including composite laminates, plastics and metals. PT326's high bond strength to plastics, including CFRP laminate, and grey colour make it a popular choice for the assembly of carbon fibre parts.

20min initial cure. Supplied in a twin cartridge pack (1:1 ratio, resin and hardener). Available to buy online in 50ml and 400ml cartridges.

Very high performance, 20 minute structural polyurethane adhesive recommended for demanding plastic-to-plastic bonding applications such as assembling carbon fibre or glass fibre composite parts and bonding clips and brackets to parts composite parts.

Permabond's PT326 is a fully rigid polyurethane adhesive with a 20 minute 1st-stage sure. Full bond strength is not reached for 24hrs.

Structural polyurethane (PU) adhesives are excellent adhesives for bonding plastic-to-plastic (carbon fibre, glass fibre (GRP) and many conventional plastics). Although PU adhesives are also suitable for plastic-to-metal or metal-to-metal bonding, in many instances epoxy adhesive (such as our ET500) will outperform PU adhesive for bonding these substrates.

Pack Sizes and Dispensing

PT326 is a professional adhesive and is therefore sold in the standard 50ml Twin Tube pack which requires the standard type 50ml Twin Tube Dispenser Gun, available to buy separately. It is also available in a large 400ml trade size twin tube intended for production use. The 400ml requires a 400ml Twin Tube Dispenser Gun. Choose the pack size you require from the drop-down list at the top of the page.

Choose the correct mixer nozzle

In both pack sizes the adhesive is supplied with 1x Static Mixer Nozzle.

50ml cartridges require a 'Type 2' 50ml style nozzle whereas 400ml cartridges require a 'Type 2' 400ml mixer nozzles (with locking nut). Click below to buy the compatible cartridges for your chosen pack size:

There is no practical minimum bond thickness for this adhesive although you do need to ensure that *some* adhesive is present, which is why glass spheres are sometimes used to prevent the adhesive from being scraped off completely. Essentially though, as long as an even thin film is applied the bond strength between the two materials will be good.

Yes, certainly. In fact the easiest way to do this is to simply leave the static mixer nozzle in place after you use the adhesive. The adhesive that's in the nozzle will have been mixed and so will cure but the glue at the start of the nozzle will be unmixed and not cured meaning the nozzle will twist off perfectly and the glue inside will have been protected from the atmosphere and so will be perfectly preserved ready for use.

A typical application of the adhesive is approximately a 0.5mm thick layer. At this thickness, one 50ml cartridge would cover an area 30cm by 30cm; a 400ml cartridge would cover an area approximately 90cm by 90cm.

For best results when gluing over a large surface area, use a spreader to help ensure the adhesive is laid down in an even layer.

Yes, PT326 will bond Carbon Fibre laminates to steel. However, our ET515 Semi Flexible 15min Epoxy and our ET500 Rigid 5min Epoxy adhesives would offer a superior bond between steel and carbon fibre in most situations.

Whilst this PT326 PU adhesive does offer a great bond on plastic to plastic (which is basically what carbon to carbon is), we generally recommend our VM100 Black 10min Methacrylate Adhesive as it has a slightly superior bond strength and resilience (toughness) in most situations. It is also quick curing and cost effective.

Although the PT326 will bond to acrylic sheet, our VM100 Black methyl methacrylate adhesive will provide a stronger bond in this case.

I don't think I would recommend our PT326 for this. Although it does offer good bond characteristics to a range of plastics, Nylon and PVC can be difficult to bond to and there may be better, specialist adhsives out there for this type of bond.

Yes, once cured PT326 has a good resistance to water. It's important to ensure the materials to be bonded are dry at the time of bonding and during cure but once full cure has been achieved then the PT326 should not be affected by water.
