Method for measuring sandability of coating and the use thereof

Abstract

The present invention is directed to a method for measuring sandability of a coating or an article. This invention is particularly directed to a method for measuring sandability of a coating or an article quantitatively by measuring weight loss of said coating or article after being sanded. This invention is also directed to a system for measuring sandability of a coating or an article using said method.

         6 . A method for measuring buffability of a coating comprising the steps of:
 e) measuring initial surface characteristics of the coating using a surface measuring device   f) buffing the coating to create a buffed coating surface; and   g) measuring subsequent surface characteristics of the buffed coating surface using the surface measuring device.   
     
     
         7 . The method of  claim 6 , wherein the surface measuring device is selected from an imaging device, a gloss meter, a profilometer, or a combination thereof. 
     
     
         8 . A method for comparing sandability of a plurality of coatings, said method comprising the steps of:
 a) measuring individual initial characteristics of individual substrates each coated with one of said plurality of coatings;   b) sanding the coating on each of the individual substrates;   c) measuring subsequent characteristics of each of the individual substrates after the step c); and   d) obtaining individual differences between the individual initial and the corresponding subsequent characteristics.
