Acrylic paint is fast-drying paint containing pigment suspended in an acrylic polymer emulsion. Paint is any Liquid, liquifiable or mastic composition which after application to a substrate in a thin layer is converted to an opaque Solid An emulsion ( IPA: /ɪˈmʌlʃən/ is a mixture of two Immiscible (unblendable liquids Acrylic paints can be diluted with water, but become water-resistant when dry. Depending on how much the paint is diluted (with water) or modified with acrylic gels, mediums, or pastes, the finished acrylic painting can resemble a watercolor or an oil painting, or have its own unique characteristics not attainable with the other media. Watercolor ( US) or Watercolour ( UK) (and "aquarelle" in French is a Painting method Oil painting is the process of painting with Pigments that are bound with a medium of Drying oil — especially in early modern Europe Linseed oil

History
Acrylics were first made commercially available in the 1950s. These were mineral spirit-based paints called Magna[1] offered by Bocour Artist Colors. Mineral Spirits, also called Stoddard solvent 8052-41-3 is a petroleum distilate commonly used as a paint thinner and mild Solvent. the world's first artist Acrylic paint developed by Leonard Bocour and Sam Golden in 1947 and reformulated in 1960, are pigments ground in Water-based acrylic paints were subsequently sold as "latex" house paints, although acrylic dispersion uses no latex derived from a rubber tree. LaTeX (ˈleɪtɛ The Pará rubber tree ( Hevea brasiliensis) often simply called rubber tree, is a Tree belonging to the family Euphorbiaceae Interior "latex" house paints tend to be a combination of binder (sometimes acrylic, vinyl, pva and others), filler, pigment and water. A binder is an ingredient used to bind together two or more other materials in mixtures A vinyl compound is any Organic compound that contains a vinyl group (also called ethenyl) &minus C[[Hydrogen H]] =CH sub>2 Polyvinyl acetate ( PVA or PVAc) is a Rubbery Synthetic polymer. Particles added to material ( Plastics, Composite material, Concrete) to lower the consumption of more expensive binder materialor to better some properties For the drug referred to as "pigment" see Black tar heroin. Water is a common Chemical substance that is essential for the survival of all known forms of Life. Exterior "latex" house paints may also be a "co-polymer" blend, but the very best exterior water-based paints are 100% acrylic. Soon after the water-based acrylic binders were introduced as house paints, artists (the first of whom were Mexican muralists) and companies alike began to explore the potential of the new binders. Water soluble artist quality acrylic paints became commercially available in the early 1960s, offered by Liquitex. Liquitex is brand name of a popular brand of Acrylic paint and Paint medium.
Techniques
Acrylic artist paints may be thinned with water and used as washes in the manner of watercolor paints, but the washes are not re-hydratable once dry. Acrylic painting techniques are different styles of manipulating and working with Polymer -based Acrylic paints. A wash is a Painting technique in which a paint brush that is very wet with Solvent and holds a small Paint load is applied to a wet or dry support For this reason, acrylics do not lend themselves to color lifting techniques as do gum arabic based watercolor paints. Gum arabic, a Natural gum also called gum acacia, and chaar gund or char goond (in India is the hardened Sap taken from two species
Acrylic paints can be used in high gloss or matte finishes. As with oils, pigment amounts and particle size can alter the paint sheen. Likewise, matting agents can be added to dull the finish. Topcoats or varnishes may also be applied to alter sheen.
When dry, acrylic paint is generally non-removable. Water or mild solvents do not re-solubilize it, although isopropyl alcohol can lift some fresh paint films off. Toluene and acetone can remove paint films, but they do not lift paint stains very well and are not selective. The use of a solvent to remove paint will result in removal of all of the paint layers, acrylic gesso, etc. " Gesso " is the Italian word for " Board chalk " (akin to the Greek word " Gypsum " and is a powdered form of the
Only a proper, artist-grade acrylic gesso should be used to prime canvas in preparation for painting with acrylic. It is important to avoid adding non-stable or non-archival elements to the gesso upon application. Acrylic will not form a stable paint film if it has been thinned with more than 30% water content. However, the viscosity of acrylic can successfully be reduced by using suitable extenders that maintain the integrity of the paint film. There are retarders to prolong drying and workability time and a flow release to increase color blending ability.
Painters and acrylic
Prior to the 20th century, artists mixed their own paints to increase the longevity of the artwork and achieve desired pigment load, viscosity, and to control the use of fillers, if any. While suitable mediums and raw pigments are available for the individual production of acrylic paint, due to the fast drying time, hand mixing may not be practical.
Acrylic painters modify the appearance, hardness, flexibility, texture, and other characteristics of the paint surface using acrylic mediums. Watercolor and oil painters also use various mediums, but the range of acrylic mediums is much greater. Acrylics have the ability to bond to many different surfaces, and mediums can be used to adjust their binding characteristics. They can also be used to build thick layers of paint: gel and molding paste mediums are sometimes used to create paintings with relief features that are literally sculptural.
Acrylic paints are the most commonly used in grattage. Surrealism in Art, Poetry, and Literature utilizes numerous unique techniques and games to provide inspiration
Differences between acrylic and oil paint
The main difference between acrylics and oil paints is the inherent drying time. Oils allow for more time to blend colors and apply even glazes over underpaintings. This slow drying aspect of oil can be seen as an advantage for certain techniques, but in other regards it impedes the artist trying to work quickly. The fast evaporation of water from the acrylic paint film can be slowed with the use of acrylic retarders. In Painting, a retarder is an Agent, usually added to Water, used to slow the drying time of Acrylic paints, giving more time for Blending Retarders are generally glycol or glycerin-based additives. In the case of acrylic paints, the addition of a retarder slows the evaporation rate of the water, and allows for more water to be added and the paint workable, until the retarder has left the film and the paint layer is dry.
Oil paints tend to require the addition of a toxic solvent, such as mineral spirits or turpentine to thin the paints and clean up tools, though relatively recently water soluble oil paints have been developed for artist use. Secondly, oil paint films become increasing yellow and brittle, and will lose their flexibility in a few decades. Thirdly, the rules of "fat over lean" must be employed to ensure the paint films are durable.
Oil paint is able to absorb more pigment than acrylic because linseed oil has a smaller molecule than does acrylic. Oil has a different refractive index than do acrylic dispersions. This changes how light interacts with the paint films.
Due to acrylic's more flexible nature and more consistent drying time between colors, the painter does not have to follow the "fat over lean" rule of oil painting, where more medium must be applied to each layer to avoid cracking. While canvas needs to be properly primed and gessoed before painting with oil, acrylic can be safely applied to raw canvas. " Gesso " is the Italian word for " Board chalk " (akin to the Greek word " Gypsum " and is a powdered form of the The rapid drying of the paint tends to discourage the blending of color and use of wet-in-wet technique unique to oil painting. Wet-on-wet is a Painting technique in which layers of wet paint are applied to previous layers of wet paint While acrylic retarders can slow drying time to several hours, it remains a relatively fast-drying medium, and the addition of too much acrylic retarder can prevent the paint from ever drying properly.
Although the permanency of acrylics is sometimes debated by conservators, they appear more stable than oil paints. Whereas oil paints normally turn yellow as they age/dry(oxidize)—and require a removable protective layer of varnish—acrylic paints, at least in the 50 years since their invention, have not yellowed, cracked, or altered.
Another great difference between oil and acrylic paints is the versatility offered by acrylic paints - acrylic is very useful in mixed media, allowing use of pastel (oil & chalk), charcoal, pen, etc on top of the dried acrylic painted surface. Mixing other bodies into the acrylic is possible - sand, rice, even pasta may be incorporated in the artwork. Mixing artist or student quality acrylic paint with household acrylic emulsions is possible, allowing the use of pre-mixed tints straight from the tube or tin, so presenting the painter with a vast color range at his disposal.
