Oil-based varnish technology is pretty easy to understand, as is traditional Lacquer. I'm having a MUCH harder time getting my head around many of the waterbased products, and their properties.
The explanation here: http://www.woodzone.com/articles/wood_finishes.htm says that waterbased products are essentially 'latex paint without pigment'. However, this doesn't seem quite right, since reports from people using waterbased poly indicates they are getting a coating that is much harder and more resistant to wear and blocking than a latex paint.
So in particular:
What the heck is a waterbased lacquer? Traditional lacquer is a nitrocellulose dissolved in solvent, which evaporates quickly and deposits coating on surface, and can be redissolved with the solvent. How does this work in a waterbased system??? Product example: http://www.targetcoatings.com/emtech-6000.html
What is the difference between a waterbased acrylic and a waterbased 100% acrylic latex? Is a product like the General Finishes Enduro pigmented waterbased acrylic essentally the same chemically as a latex paint? http://www.generalfinishes.com/indus...industrial.htm
From the same GF link above: What the heck is a pre-catalysed Urethane? What makes it different from a 'regular' waterbased polyurethane like this one: http://www.woodcraft.com/product.asp...0&FamilyID=756
If a waterbased polyurethane dries harder and without blocking/stickyness than a latex paint, why aren't folks dumping pigment to the WB poly to make a colored opaque furnature coating?
Could go on and on... but this is a start at least.
