Amber shellac has a warm, orange cast that gives woodwork a rich, antique character. Clear shellac dries translucent with a faint, golden cast that is significantly lighter than oil-based varnishes.

We're talking about using as a primer, not a topcoat.

Not talking about "BIN", rather just clear shellac. I have no doubt that it adheres well, but more of a finish then a primer?
Reduced dewaxed shellac will act as washcoat and somewhat seal the surface, depending upon how much it is reduced. Washcoats are especially useful before trying to stain blotch-prone woods. Zinsser SealCoat would be considered a sealer. I generally think of pigmented "sealers" as primers, although I doubt that's where the experts would draw the line.
In regards to your question on a different post, "I had also thought about that. Although the shellac may be hard to bond too?"
Not sure if I'm understanding the question, but almost anything sticks to shellac, (although many will caution against applying a poly over waxed shellac).

Not really ever using just clear Shellac, I was under the impression that it was a hard slick finish, therefore being harder to bond too. I was never sure on this though..It was more of a question whether it could be used as a primer over a previously finished product.

I was under the impression that everything sticks to (de-waxed) shellac, and that shellac is a universal sealer (sticks to everything).

Anyone know for sure?

if it is a lacquer substrate finish that you are working on,if you did not dewax, gave a good lacquer thinner treatment and a sanding first,de waxed shellac has a very little sticking effect on to lacquer.
It is sometimes easy and safe to use on raw wood to seal before staining as a wash coat but not for refinishing situations.
Lacquer to lacquer is very safe and easy finishing schedule.rest of them is a bomb on a timer.you never know when it will fail.All you need a cool flow mask and a well ventilated area to spray.

What i know BIN is a spot primer.De-waxed shellac is a sanding sealer.Two different animal.
This is not a debate starting or anything but all different products has different use.You do not have a bare wood to seal .You have a wood that is already finished with lacquer.
If you insist not to use any type of lacquer product and you want to play safe you will have to strip that wood or you will have to soak in some lacquer thinner and break the lacquer substrate so that you can sand after and let the BIN stick easy.
Trust me on this BIN or de-waxed shellac has nothing to do at your project.If you are not comfortable spraying lacquer vinyl sealer or sanding sealer please find somebody who sprays for you.After you can spray color with any type of material.water or solvent.

I prime over lacquer with BIN all the time. They say spot prime on exteriors only. Interior is fine. It has better adhesion than any primer I've ever used. It's the clear dewaxed shellac I'm wondering about..

Yes i did.One is spot primer and other is sanding sealer and none of them work properly on your project.
If you want to learn more please download msds.Since i do not use BIN as a wood primer and i cannot say what is it made or what is the difference.
On the other hand De-waxed shellac is nothing more than a #2 cut 17 percent solid clear shellac.Not suppose to be use for refinishing.Just as a wash coat to control the stain strength on the bare wood surface.

I’m not interested in lacquer, my interest was/is learning about BIN and Dewaxed Shellac. Which is why I asked about it. Still don’t really feel like I know the technical difference between the two.

BIN is Shellac-based, so how different can they be?

BIN is pigmented shellac which its self has well documented adhesive qualities dating back thousands of years. Of course the industry has moved onto synthetic resins that are easier and cheaper to produce among other qualities.

In reference to using shellac as a prestain conditioner however I have found it inferior to other solutions such as Benite, or glue size and a few other off the shelf waterborne options.
