What is it?  TDS says it's a waterborne acrylic. Now I'm confused.

I see this as a water bourne lacquer, thus the name. It does contain acrylics, but if you look t the SDS you'll see it also contains naphtha and other solvents.

Thanks Tom. Very interesting. Would that be the same with KA plus?

Only the Duralac WB clear contains the naptha and solvents, the opaque finishes contain ethanol. A lot of opaque finishes WB contain some form of alcohol or solvent as part of the emulsion. You will also find a hint of ammonia in a lot primers, IMHE, the ones that seem to work well.

Thanks John. I have noticed that when I open the can I do smell ammonia. This is the primer that I find works the best for me.

I guess I'm confused...so what is the definition of paint, as in, what can it contain and what can't it contain?

I look at it as more than what it contains. I look at the TDS to se how it should be applied, how they define the sheens and what it's intended purposes are.

Link to TDS for the clear;

http://lenmar-coatings.com/product-detail/pro/lenmar/duralaq-wb-waterborne-acrylic-clear-finish

Application is spray only. Can't be brushed or rolled.

The sheens are defined, starting with Dull Rubbed to High Glass I see these as finish definitions For some reason they don't list the BGR number).

The "Recommendations" are for casework/woodwork items.

Due to all of the above, I look at this product as a finish, not a paint. My definition in my little corner of the world. ;)

Tom was right, it's not paint. Just talked to the techs at Lenmar and they classify it as a waterborne acrylic lacquer. If that makes sense.

Lacquer is a subset of paint. Paint is any liquid, liquefiable, or mastic composition that, after application to a substrate in a thin layer, converts to a solid film

Now that that's done I'd love to hear why you switched to this product....

Why I changed? Good question. There are a number of reasons.

1) Thought of going with Kem Aqua line but it is not readily available here. There is a SW store 45 minutes away but they will only sell you 5 gallon drums. If you are a volume customer they will do 1 gallon pales. Our local SW dealer will sell me white Kem Aqua only. Nothing tinted.

2) The majority of my customers use Benjamin Moore colours and paint so I wanted to stay in that product line. As they own Lenmar Coatings, it is possible to tint the Duralaq product to any BM paint colour.

3) I wanted a coating that could be applied with my 3 stage and T70 gun. I have had success in spraying BM Advance and Regal Select by conditioning it with BM Extender ( For the Regal line ) and water for the Advance product. The only issue is that these paints take forever to dry. The Duralaq product can be re-coated in 30 minutes.

I'm still doing a lot of trials with this "paint", but the Duralaq Waterborne Acrylic is showing promise. Need some more practice though.

Now, if Santa Clause is good to me I will upgrade to a CAT technologies AAA system. I will then use my 3 stage for polyurethane only.

Cheers,
JC

The term "lacquer" when used in conjunction with waterborne coatings is a marketing term. Traditional solvent based nitrocellulose lacquer are quite different in their structure and how they bond to each other than waterborne acrylic coatings.
There is a very good article by Bob Flexner in Popular Woodworking Magazine on why water based finish isn't lacquer
You may need a subsciption to read it, but well worth it.

The Lenmar products are great  IMO.  I've tried a lot of different brands, including the ML Campbell products, and much prefer the Lenmar products.  I've use that acrylic along with its companion sealer and it's pretty awesome.  It's not solvent awesome but it works really well for a water product.  If I had to spray something in the field where I couldn't use solvent based CV this would without a doubt be my go-to.

There seems to be some urban use where the term "paint" is infers opaque, and differentiated from a stain, a clearcoat, varnish, or a sealer.
And a primer could be opaque or a clear.

It's sort of like saying "<a particular person> is an animal", or "people are animals", has a much different meaning from people fall under under the animal kingdom as biped mammals under primates, Neanderthals, etc.

I always think of a paint as having a color.
