I have made a tough decision, our formulas for the regular build primer has been our flag ship for 15 years and hands down, I have never tested a primer as good, my idea of good is not how it sprays but how it holds up down the road as our business is high end cars not used car work.
Six months of testing and playing I have settled on a new formula the 6520 is the first one and that batch is Jan/16 on bottom of can, the buff and black will also be changed when we make more.
I totally changed the resin to a newer much more expensive one; added more different types of Nano’s (3). AKA slang, microspheres.
One of the things I did not like with the old was if the inside of the can cooled it would thicken pretty fast, the new resin of course can but not as bad and this was due to one of the corrosion inhibitor’s as well as the old resin causing this, just 10 degrees could make the other where it depending on gun need a splash of reducer to spray. With the new resin and changing the ratios of the different corrosion inhibitors, I have reduced this issue to a point. Bottom line if inside of can is 55 degrees it will be a little thicker than normal.
Viscosity! To keep the OH/NCO ratios so the 6501 activators we have out there will work just fine, best guess would be 10,000 on any given day, as we sell about 1800 a month more than is needed on an average, with the new resin its about 2-3% more thicker then I wanted but that is the safest way to go.
Bottom line: Mixed 4:1 it sprays well out of some 1.7’s but not all, sprays good out of all the 1.8’s I have, so there is a sticker on the top of the can that says depending on gun okay to reduce as needed. The one 1.7 that did not spray well I added 2% urethane reducer to the activated mix and it sprayed nice and slick.
I’m excited about this new formula as once again it goes with the SPI attitude to make the very best, not just to stay the same or just get by.
This formula has increased my cost just over $4.00 a gallon but I’m so in love with this formula I’m eating that cost, so price is the same.
