Hi,  Technetter,
    We are using epoxy & PMMA as a coating material to protect thick
film. However we are seeing problem. Does anyone know the spec of these
coating material , like water absorbability spec(@100C degree, 2hrs)  or
vapour absorbability spec? and Please advise some better coating
material for protection of thick film?
It is urgent for  line stop.  Thanks in advance!
Davis
