Hi good people, you are the best resource I have at hand, so I'm throwing this out to you all:

At work, I/we utilize 2-2.5 gallon pressure pots that hold 2 similar liquid (gloss & matte) materials (basically glue) that we use to coat our products with an hvlp gun using 10lbs pressure in our spray booth.

Some clients want a combination of the 2 coatings to create a 3rd semi-gloss/satin finish. Best case scenario is that I could mix/blend the 2 in-line somehow, because we could easily customize the coatings per the client's request.

It's logical to me to relate these 2 liquids as something similar to hot and cold water, and I want to be able to coat my products with hot, warm or cold liquid using a manifold to dial the percentages.

As I'm writing this, I feel like it would be ideal to have some type of ball valve at the gun, receiving the two fluid lines, and allowing me to dial the mix right there.

Does anyone know what I'm trying to say, and have a direction to share?

Thanks-
paul

nice.

thanks.

i get about 10% of it, so i'll get studying.

i'll get flow rates and the rest of the specs tomorrow, it's busy now---


i was about to post this and i couldn't. now that i'm finally home: (and i'll post pics tomorrow.)

jd74914, it sounds like your metering at the pot right? ideally i need it at the gun, or feeding one liquid line to the gun. it'd be good to spec the customers mix too, but we're a production house mostly, and only want to offer a limited number of options (working with artists, here). ideally, 5 options from gloss to matte.

the liquid is heavy glue cut with distilled water. it has sediment and the pressure pots have agitators that warm the product too.

more ina minute
