Nylon ink Catalyst - Air dryable?

[Inkworks]

I have a project for printing on large Cordura Nylon bags that will be too large to take a trip through the oven, the customer mentioned a different shop used an ink that "air dried" The sample sure looked and felt like plastisol. I'm wondering if regular plastisol with nylon catalyst would work, perhaps with a decent flash-cure to kick start it.

I guess my real question is: Is there a difference between Nylon Bonding Agent additive and a true Plastisol ink catalyst that will cause the ink to set up without a heat-cure?

Right now we have QCM QB 6600 (MF-66) which is called a "bonding agent" and while it works well, it's definitely different than the old catalyst I used in previous shops that would cure solid in the mixing container after 2-3 hours.

input? suggestions?

What you have in the bottle is the Rutland bonding agent.

And no, it does not cure solid in a few hours... or days really.....

As always - If you can heat the ink deposit up close to 300, it will really help to make the ink and catalyst bond well.

So what is the good old catalyst that sets the ink up solid in a few hours, i believe we used to get it from Wilflex, but that was 15-20 years ago. It was a bit of a pain as the agent itself would harden in it's own container after a year or so.

I know other ink companies went to a different formulation when the Ortho Phthalates were banned.  The good stuff had it in them.

At QCM we found a formula that worked great.... but its no longer in use.

I have not found anything that is close to like it used to be. 

Even International Coatings jacket catalyst does not harden up over night.....

Permaset has air drying ink for this.

And they are in the States now. Finally

When I was with Riddell we used to print some large nylon bags that the dryers could not accommodate - could not wait for overnight curing(plus room for drying always an issue. Usually could find a way to use one of our heat presses(had clam shells and swing-aways in a number of sizes) with Teflon sheet to cure the ink.
