b. It smoothes the surface texture preventing the retention of grime and other contaminants, thus reducing still further the rate of surface attack.
c. By smoothing the surface texture the appearance of the coating will remain cleaner and more attractive than without a sealant, and may more readily be maintained in a clean condition.
Testing Procedure :
As per IS & BS standards we carryout the job of Metallizing/Aluminizing to the coating thickness of 150 to 175 microns this as to be confirmed by thickness measurement gauge before giving for sealant application after application of sealant the final coating thickness should be 175 to 200 microns. |
