Acrylic: CH2 = CH-CN
This is an aqueous emulsion of acrylic polymer with pigments, esters, acetylene. Polymerization of synthetic resins formed around a plastic resin pigments, when the paint is dry.
The manufacture of acrylic is complex, the pigment is first crushed in water to which are added additives and not in the medium as is usual for other paintings, the particles are then dispersed in the acrylic emulsion. These are chemical additives that will give its consistency and malleability and its brilliance. Resins often differ from one manufacturer to another, it is advisable to avoid mixing different brands between them and preferably stick to one.
is a painting which thins Water which requires no solvent, no toxic, odorless solid.
Drying is very fast, since the evaporation of water molecules polymerize by themselves and form a coherent structure. Then obtained a pictorial film matte, uniform, flexible and indelible. Film of great elasticity, which after drying the paint is expected to remain stable indefinitely, resistant to chemicals and weather. Next
dosage of painting more or less diluted with water and the gesture of the artist, it can be connected to temperature, gouache or even watercolor.
The consistency of the cheese is reminiscent of the oil and can be used right out of the tube with a brush, painting knife.
As for oil painting, there are fine colors or extra-fine (obtained from the finest pigments in high concentrations and often monopigmentaires). The quality of the painting depends on the quality of the pigments used and the amount of resin relative to the amount of water. Color pigments containing substitutes and the load are available at very low prices, they are much less stable and generally used for studies.
color tube is thicker and dries more slowly, the color pot is smoother, dries faster and is generally used for large flat areas.
Today Various mark offer a variety of shades, sometimes with metallic colors, fluorescent, and even beaded.
