WebIn water-borne coatings, an aqueous polymer dispersion creates a film on the substrate once the solvent has evaporated. Surface functionalization of the polymer particles is a key component of a coating formulation allowing control over such properties as dispersion, film formation temperature, and the coating rheology. WebHow the polymer and the additives are combined to produce a final formulation is obviously very important and the distribution of components within the system can be critical to the desired functionality. In many instances homogeneity is critical, ie colour to avoid patchiness, pharmaceutical active to produce a constant release rate.
