However, by careful selection of the particular type of extender for specific paints it is often possible to improve certain properties of the paint or the dry coating. Proper choice of extender may improve properties such as consistency, leveling, and pigment settling in the paint. Certain extenders reinforce the structure of dry coating mechanically, while others increase its resistance to the transmission of moisture.ln paints with high pigment concentration sufficient hiding may be obtained by replacing sonne of the opaque pigments with extender pigment. Detailed knowledge of the various types and grades of extenders will enable the paint formulator to produce paints having maximum properties at minimum cost.Numerous properties of extenders are discussed here along with their suitable end applications.
