How to calculate optimum thickness and coverage area?

hello, dear colleague try with calcute the weight of the specimen before and after formation of the coating

Do you mean by measuring the wet film coating thickness (WFT, in microns) and the dry film coating thickness(DFT, in microns)? That would obtain the solid volume ratio % (SV%) by using
[(DFT/WFT)*100%].

From that, i could get the theoretical spread rate(m^2/litre) at that particular DFT by using
[(SV%/DFT)*10]

If the aboves are workable, can i subject the DFT to secondary test such as thermal and physical test?


Regards,

Is your goal to "subject the DFT to secondary test such as thermal and physical test?"

Or, is your goal to determine how much solution to apply to a surface to meet specification thickness?

Hi there, thanks for your reply.

My aim is to find out the theoretical coverage area that this certain amount of "coating solution" can cover. And i need to know how to find the optimum thickness for this coating solution.

Thanks!


Regards,

The surface force is needed for determining the theoretical coverage. How well the fluid spread across the surface depends on the interfacial force between them.
