MY ANNUAL EXPLANATION ABOUT "LATEX PAINT" BEING UNRELATED TO "LATEX
RUBBER".

The word "latex" in general and with regard to paint means "emulsion",
nothing more. The emulsion may be of acrylic, or other things like
polyvinyl acetate or natural casein. The term "latex paint" tells you
nothing but that the paint is a water-based emulsion. It does NOT tell
you what species of polymer.

"Natural latex", often confusingly just called "latex", is the rubber
tree sap, an emulsion of natural rubber. This has nothing to do with
"latex" paint. "Latex rubber" is rubber made from natural latex.
Before modern polymers, this was the only latex polymer, so in those
days "latex" almost always meant natural rubber emulsion, leading to a
misunderstanding today in peoples minds.

Many plants have latex sap, not just rubber trees.

The word "latex" means the liquid that comes out of certain plants, like rubber
trees and milkweed. The word "latex" on paint refers to a synthetic form of
latex that is used as a binder.

Latex in no way or context means "emulsion", except in the mind of Kinch. Look
it all up in a dictionary. Kinch is a usenet kook, who also believes that WD-40
is a healthy thing to drink. That may be why he comes up with all these other
strange and erroneous posts.

Kinch will no doubt reply to this post, but as I said, the dictionary is your
friend. Kinch is not.

I'm no chemist but his post certainly seems accurate to me. Dang site
better than people thinking latex paint is made with rubber (even though
the miserable stuff sands as if it were).

LATEX
A milky-white, fine dispersion of a solid resin in an aqueous medium.
Also used to describe water-thinned paints, the principal vehicle of
which is latex.

LATEX PAINT #1
Paint containing colloidal binder particles formed by emulsion
polymerization. A common term for water-based and water-reducible
coatings.

EMULSION #1
Liquid droplets dispersed in another immiscible liquid.

EMULSION #2
A colloid in which both phases are liquids

LATEX PAINT #2
Water-based paint made with a synthetic binder (latex), such as acrylic,
vinyl acrylic, or styrene acrylic latex.

???

Your definitions say Kinch is wrong. Review what he said, and then
have someone parse these definitions for you.

"Latex" is not an emulsion. SYNTHETIC latex is used as one ingredient
of an emulsion that is included in so-called latex paint.
