General name of liquid paints with a solid content considerably higher than that of the conventional paint. High solids coatings are gaining attention because of reduced effects on environment due to low volatile content and short application times owing to the fact that with high solid content less time is needed to achieve the same dry film thickness. The aim of high solid coating formulation is, achieving application viscosity by adding minimum amount of solvent to the non-volatile constituents. Therefore, use of reactive monomers or oligomers, low molecular weight polymers, dispersion additives that can considerably reduce pigment paste viscosity, in addition to use of solvents that can reduce binder viscosity and reactive diluents which stays in the film by participating in crosslinking reaction are the main strategies in designing high solids coatings.
