the main components of paint dispersants usually include organic solvents, Surfactant and stabilizers.
Organic solvents: common organic solvents including acetone, methanol, ethanol, butanol, etc. , used to paint pigments dissolved, so that it becomes easier to smear and uniform dispersion.
SURFACTANT: the Surfactant reduces the surface tension of the liquid, causing the pigment to disperse evenly and preventing the pigment from precipitating in the paint. Common Surfactant include sodium dodecyl benzene sulfonate, octyl phenol polyoxyethylene ether, etc. .
Stabilizer: stabilizer can prevent pigment in paint caking and precipitation, improve the stability of paint and shelf life. Common stabilizers include polyacrylate, polyvinyl alcohol, etc. .
In addition, paint dispersant ingredients may also include preservatives, antioxidants, etc. , to improve the paint antibacterial, antioxidant properties. Different types of paint dispersants may vary in composition, the specific composition of the product according to the formula to determine.
