[MW:3329] Re: Painting

Dear

 

The problem is coming from inorganic primer which might be with more DFT.Either you have to control the DFT or during application of intermediate coat,first apply mist coat then followed by required DFT.Same procedure to be followed for top coat.This can resolved your problem due to escaped gases from primer during mist coat application.

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.
