You can learn more than you need or want to know about latex paints at the Rohm & Haas "Paint Quality Institute" web site.

Paint Quality Institute - Painting information and resources for home interiors and exteriors

The Paint Quality Institute was established and is funded by the Rohm & Haas Company to teach architects, professional painters and paint consumers (presumably people who drink paint) about the benefits of using top quality latex paints. Part of that effort was the publication of several brochures that were available free of charge in paint stores across North America:

Continuing Education Requirements for painting tips and advice - Paint Quality Institute

Download and read:

"The Ingredients of Paint and Their Impact on Paint Properties"

and, if you're interested in the pigments used to give paint colour and opacity,

"How Colour is Affected by the Ingredients of Paint".

If you read and understand the first of these two brochures, you'll know more about latex paint than 95% of the people working in paint stores.

That "Continuing Education Series" was replaced with "PQI Magazine" which contains articles about latex paint, but these articles are really "dumbed down" so far as the chemistry and physics of paint film formation goes.

Dr. Otto Rohm and Mr. Otto Haas formed a company called Rohm & Haas in Germany which originally produced a chemical that was used in the tanning of leather. The company grew during WWI with the demand for leather for boots and uniforms. After WWI, Haas moved to Philadelphia to establish the company in the United States, and Rohm & Haas was the first company to cast polymethyl methacrylate (PMMA) into sheets. They called these cast sheets of plastic "Plexiglas", and with the outbreak of WWII, the Rohm & Haas Company manufactured Plexiglas canopies for both American and German warplanes. The Rohm & Haas Company was the largest manufacturer of the acrylic resins used to make latex paints, acrylic floor finishes, grout and masonry sealers and nail polish for the ladies in North America until 2009 when they were purchased by the Dow Chemical Company.
