WHAT IS ACRYLIC PAINT?

Water-based acrylic paint is composed of pigment particles dispersed in an acrylic polymer emulsion. There are three main components in any acrylic paint - pigment, binder and vehicle:

1. Pigment - pigments are granular solids which give paint its color. They are milled to a tiny particle size and do not dissolve, but remain suspended in the paint. Pigments can be organic, inorganic, natural and synthetic. They have little or no affinity for the surface to which they are applied
2. Binder - a binder is the substance that keeps pigment in place after the paint dries. Acrylic paint has acrylic polymer as its binder and this forms a film after the water has evaporated
3. Vehicle - this refers to the part of the paint that carries the pigment and binder. Water is the vehicle for water-based acrylic and when combined with the binder, it creates a polymer emulsion. Once the water leaves the system via evaporation or absorption, the paint dries, creating a stable clear polymer film full of trapped colored pigment particles

THE SCIENCE

Acrylic colors dry as a result of water evaporation. Here’s what occurs as pigment, water and acrylic are transformed into a long-lasting paint film:

Stage 1.

Squeezed from the tube, or scooped from the jar, acrylic paint is a finely balanced dispersion of pigment in an emulsion of acrylic polymer and water. The water serves to keep the emulsion liquid and acts as a kind of chemical ‘chaperone’, preventing the acrylic polymer particles from getting close and personal and locking together before you're ready

Stage 2.

When exposed to the atmosphere, water in the emulsion evaporates, or is absorbed into the painting support. That’s when the acrylic polymer particles come into direct contact and fuse with each other

Stage 3.

The clear polymer particles organize themselves into a stable, hexagonal structure, trapping the pigment in place. The result? A paint film which is extremely stable, water-resistant, permanent and vibrant
