Acrylic paints


Acrylic paint is a fast-drying paint made of pigment suspended in acrylic polymer emulsion. Acrylic paints are water-soluble, but become water-resistant when dry. Depending on how much the paint is diluted with water, or modified with acrylic gels, media, or pastes, the finished acrylic painting can resemble a watercolor or an oil painting, or have its own unique characteristics not attainable with other media. Acrylic paint is typically used for crafting, or in art classes in schools because it does not require any chemicals, and rinses away with just water. It also is less likely to leave a stain on clothes than oil paint.

As early as 1934, the first usable acrylic resin dispersion was developed by German chemical company BASF, which was patented by Rohm and Haas. The synthetic paint was first used in the 1940s, combining some of the properties of oil and watercolor. Between 1946 and 1949, Leonard Bocour and Sam Golden invented a solution acrylic paint under the brand Magna paint. These were mineral spirit-based paints. Acrylics were made commercially available in the 1950s.

Following that development, Golden came up with a waterborne acrylic paint called "Aquatec".Otto Röhm invented acrylic resin, which was quickly transformed into acrylic paint. In 1953, the year that Rohm and Haas developed the first acrylic emulsions, Jose L. Gutierrez produced Politec Acrylic Artists' Colors in Mexico, and Henry Levinson of Cincinnati-based Permanent Pigments Co. produced Liquitex colors. These two product lines were the very first acrylic emulsion artists' paints.

Water-based acrylic paints were subsequently sold as latex house paints, as latex is the technical term for a suspension of polymer microparticles in water. Interior latex house paints tend to be a combination of binder (sometimes acrylic, vinyl, pva, and others), filler, pigment, and water. Exterior latex house paints may also be a co-polymer blend, but the best exterior water-based paints are 100% acrylic, due to elasticity and other factors. Vinyl, however, costs half of what 100% acrylic resins cost, and PVA (polyvinyl acetate) is even cheaper, so paint companies make many different combinations of them to match the market.
