                 Understanding the application
                        Final product specifi the coating are achieved in the  blending (thinning) stage. The  blending stage  involves reducing  or thinning the coating to ensure  that the tint, durability and the  coatings ‘film’ properties are     exact to specification prior to     packing and shipping to the   coater.   This is often the most critical  stage and consequently may  require recirculation of the batch  through filters to control the     pigment size distribution and  re












                        Following the dispersion of the  ‘premix’ the pigments that  characterize the coating are  added to form a viscose paste  called the ‘mill base’. The mill  base is loaded with pigments of  varying size distribution that are  not consistently mixed and are   agglomerated.    The mill base is then ground or  milled to achieve pigments of  the required size so that they  disperse in the coating uniformly  and provide the character of the  coating for intended fun
