PT326 20min Rigid Polyurethane Adhesive

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.

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, 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.
