Retarder

I have been working on this for a few months and was going to make a retarder for clear and one for 2K primer and epoxy.
What I decided on was make one for clear and our people are smart enough to cut it back if using in primer or epoxy and that way you will only need one item in inventory.

Labels are being worked on now and should have in a month but the short of the story is, one to four ounces to a mixed quart of clear and one to two ounces for a mixed quart of primer or epoxy.

Made for 80 degrees and up and will work every well in last coat of clear as a flow coat.

Package will be a quart activator can and price will be $25.50.

Part number 925-4.
 
Any idea on how the new retarder will impact the gloss level of the epoxy? I think it might be nice to use on large jobs during the summer, there were a few times when I had trouble keeping a wet edge.
 
This is awesome.. In summer time, reducer is the only way sometimes to keep a wet edge. It will be great to only have to add a splash of retarder instead of reducer.. My cans of SPI are the ones that have flow indicators built into them :playful:
 
I have only tried with one ounce per mixed quart and with the assumption the other coat of epoxy was laid slick, then this does not change the gloss.
BUT if the other panel was not laid real slick, then the extra flow will make the epoxy gloss more, not much but looks to be about 1-2%.

Personally, I can see a lot of use for this retarder but I will say for last coat of clear, I have done 2oz and a 4oz and it made a painter out of me.
 
My only concern was, if done right the primer and epoxy retarder is normally a weaker blend, so you can use more with out too much concern.
I decided that we give enough info to our users, that we could take a chance with a full strength blend and the customers would know to cut usage in 1/2 for the primers, just more for your money but I just hope, I made the right decision.
 
I don't know if anything will turn me into a painter, but maybe the new retarder will turn me into a waterfall sculptor. :D

In the words of Foghorn Leghorn "I say, I say...pay attention boy".:p
 
Make up a double sided label, one half says 2k / epoxy retarder with specific instructions and a note saying see other side for clear. Repeat in opposite colors on other half with clear specific instructions and a note saying see other side for clear. Think black with gold text, then other side gold with black text ?
one label - applied to the can, looking from 1 side it is for epoxy, rotate can 180 degrees and it is for clear. is that clear?lol.

Please explain to me what the purpose of the Retarder is for? I consider myself a beginner since I have not done an all over paint job.
 
For primer it would be used when doing large areas in hot weather, very much needed in SE in summer times.

Clear could be used for same reason but I see it more as a finale flow coat.

Something I did the a while back had a panel the after three coat busted out in solvent pop, here and there, my fault for rushing last coat.
Added, some to clear and sprayed a double coat non stop, not a pop left, now that was a flat surface, so a side panel you would need to be more careful.
It was pretty when done, kind of left me speechless to turn a cluster, into a perfect surface.
 
Sometimes in those panic moments is when you discover a new trick.. Or usually in my case a cause of disaster.
 
Had a chance to use the retarder in the universal with very slow activator and I gotta say, this is a savior.

Even though the very slow is the cats meow to universal, sometimes it is still tough in my downdraft at 85-95 degrees on all overs. I give up anything higher that 95..LOL..almost torture. No longer an issue with the retarder. Good stuff!!
 
Well first time I used it, I believe I used 1 ounce per mixed qt...that helped but wasn't quite enough. It was about 88--92 degrees this time and I used 2 ounces per mixed qt and worked great. I know the can says 1-3 ounces but was a little shy on using 3 ounces. Maybe when its 95+ but I all but quit spraying all overs in those temps, no matter what paint system. No reason to torture your self for hours at 100 degrees..lol.
 
Thank you sir, that is the feedback I have been hearing but value your info.
 
What is the breaking point of the retarder? I have been using a cap in 3oz of universal with xslow activator in all coats. Using an Iwata LPH300 with 1.3. Still getting dry spray esp on upper portions of panel.

Would you suggest adding reducer or more retarder or get a 1.4 tip?
