This project was built in a class I was taking at the local tech college, and they will not allow polyurethane finishes in the finishing room in the shop. Most everything that comes out of that shop is top-coated with pre-catalyzed lacquer, which students have to buy from local sources. The finish supply stores around here carry only gallons and up, nobody else in the class needed any, and with a pot life of 3 or four weeks, there was no way I would use that much, so I would just be throwing it away.
I decided to try something different, and ordered EMTECH EM6000 from Target Coatings … http://www.targetcoatings.com/shop/products/EmTech_6000_Production_Lacquer_Satin_32oz-273-32.html . When I start spraying in my own shop (I recently acquired an Earlex HV5000), this is the stuff I will be using.
First off, you can’t beat water-based finishes for easy cleanup … no solvents, thinners, etc., so cleaning up the HVLP gun at the end of the evening was no more difficult than helping my wife with dishes.
Viscosity, out of the can, was perfect for the gun I was using, so there was no need to thin it.
The self-leveling properties and fast-drying time (20 to 25 minutes in my case … their finishing room has an excellent air filtration/circulation system) made it possible for me to build a terrific finish in a very short amount of time. Including sanding between coats, I got 6 coats of lacquer on my project in something under six hours … no runs, no sags.
Another thing I like about this stuff … I called Target Coatings, and was informed the ‘pot life’ is one year from the date it is opened.
Here’s the manufacturer’s description:
