The role of surfactants in the emulsion polymerization process
To create a synthetic latex, the main component of water-based paints and adhesives, the leading process used is emulsion polymerization. Monomers (acrylics, methacrylics, vinyls, etc.) are polymerized in a water-based medium using radical primers, where surfactants are required to stabilize the system during polymerization, and the dispersed polymer particles formed. The batch polymerization process consists […]
The importance of wetting and dispersant surfactants in the dispersion process
The pigment dispersion process can be divided into three stages: wetting, dispersion/grinding, and stabilization. In wetting, it is important to use an additive that can reduce the surface tension of the water, enabling it to penetrate pigment pores thereby wetting of the pigments to be dispersed. In the dispersion/grinding stage, the pigment clumps are mechanically […]
Surfactants in paint formulations
Surfactant molecules are composed of polar and nonpolar ends. The polar end, also called the hydrophilic end, is water-attracting. The nonpolar end, also known as the hydrophobic end, is water-repelling. Surfactants have applications in a number of different industries, such as food, cosmetics, pharmaceuticals, agrochemicals, and paints, and it is this association of two polar […]
