Dear Saravanan

 

This may be improper mixing & application of Intermediate coat. Please check I.M coat  thoroughly, repair if required and than apply Top coat.

 

please also note that inorganic zinc need more humidity for curing. Ensure primer cured completely by rub off test. Normally this system taked more time for curing  Primer. If you r having less humidity, than sprinkle water to promote the curing fast.

Dear Guys!!!!!!!

 

The project which I am involved following the paint systems as per client spec follows:-

 

Inorganic Zinc(75-100 micron) as a primer

High Build Epoxy(100-150 micron) as a Intermediate

High Solid Aliphatic Polyurethane(40-100 micron) as a finish

 

Total Dft between (215-350 micron)

 

After the complete curing of the finish coat visually I observed tiny pinholes like appearance or fish eye only inspector eye can find them.

 

Please give me the suggestion where the problem from? this appear in almost all the painted works which applied many different days, different paint batch followed by airlesspray method.
