PPS cups accuracy

I haven't used those but I have used the plastic measuring cups you get from the jobber and found them to be off. So I don't trust anything other a separate can (I ask for one extra with every paint order) and my measuring stick I got from my PPG jobber.
 
We go through a ton of USC quart and 5 quart painters pails and a few years back the warehouse sent us 5 star because they were out of the USC.
All my gel times were out of wack with my batches and once you set the gel time on a product, if nothing else changes in the formula as this is added say 300 to 1100 grams per 300 gallon batch, it should always be with in a few minutes.
That is when i checked the cup by grams and it was way off, sent back to the WD and said never send anything but USC again. None are exact but usc was at that time within 1%, so I can live with that.

PPS types never have tested.
 
Thanks.I will do a test and let you know.I just think its a little shotty to slide a piece of plastic in between the cup and liner and expect it to be accurate when it can move around.
 
I would think those paper strips would be more accurate, just because of how they are printed. There is no deflection or rolling involved like when they are printing the clear cups. We got some, but never really thought about mixing in the PPS liner. Each time I ordered what looked like the outside cup with the printing on it.

The bad thing is you may not know until you get to the end, like mixing epoxy 1 to 1 and when you run out of epoxy and mix in the proper amount of harder and you still have some left over. That is what happened to me and how I found out luckily I had no bad issues but I knew something wasn't right, both epoxy mixes and clear mixes came out with extra material left over from one part or another and so I just use the measuring stick now in an extra paint can.

I thought about going to a craft store and getting a glass measuring mixing beaker for chem. or a glass kitchen measuring cup for mixing paint and primer but just haven't got around to it yet.

Know of a paint guy in GA. he will use his wife's kitchen measuring cups in his plant cleans them out then back in kitchen before she knows what happen! keeps cost down LOL
 
The closer to 1:1 a product mix is, the less sensitive it will be to mixing error. It is perhaps no mistake that SPI's two flagship products, Epoxy and Universal Clear, are both 1:1 mixes with their activators.
 
Always use the big numbers Like the 1-10 or so on side of cup.
To check number use water and a gram scale.
The plastic cups are high seed lazier printed and more likely a say 4 to 1 mix in the small part will be off more then the big numbers.

I thought I saw where Barry said they overfill so that would not be an accurate way to tell.
I used a burette to fill a cup and it is actually accurate.Thanks
 
i use the pps mini cups with the slip in scale to mix single stage 8:1:2 so far ive had no problems
