Low Temp White

[Maxie]

We are getting a lot of orders for printing on synthetic material bags.    At a high oven temp they melt.
We are printing with a Wilflex Tiger white and lowering the oven temp which means that they are not curing properly.
Is there a good white that will cure at a lower temperature or a additive that will get plastisol to cure at a lower temperature.
Thanks

Use water base or transfer.

Xenon has a white that cures at 258 degrees.  $75 per Gallon

What type of synthetic material is it?  We print tons of nylon bags for one of our customers and just add Nylobond to standard plastisol, run it through the dryer at 225 for about 25 seconds (to dry it to the touch), and let it air dry from there for a day or two before delivery.

And yes, also, most major ink manufacturers have a low cure additive as well.

For me, since the chemistry is obviously there,  it has always begged the point, " why not lower the cure temp on all plastisols in the first place" The energy savings would be a boon as well.

This is very good point. Its beyond my understanding as well. 20% is calculated saving on dryer energy cost.

Many folks undercure the inks on these anyway.  Generally not a huge deal as they do not get washed --- full cure for the most part is for washfastness.  I do agree that adding a low cure additive is a good idea,  Or any in that cures below 300f should be fine.  You mentioned WIlflex -- Top Score White cures at 285.....
