In Organic Chemistry, polyacrylates are a family of polymers deriving from salts or esters of acrylic acid or from their methyl derivative.

They are often used as thickeners for aqueous solutions and are marked by high transparency, elasticity and an important resistance to breakage.

They are better known as acrylics and they are widely involved in cosmetic production, usually perfoming as binders.

In Ceramics, they are especially used to lower the viscosity of aqueous systems applied along the glazing lines (engobbi, glazes and grits), thus promoting a deflocculating and/or dispersant effect.

This result is obtained by means of an electrostatic action, that is through an "interference" with the electric charges of the suspended solid particles that produces a repulsive effect.

Based on the molecular chains of the polymer, polyacrylate is sometimes also able to promote a binding action.
