I am trying to coat my material on steel coating but the final coating is producing cracks ?

last month 1 7K Report

I am using zn as active material using 90 mg with 20mg Polyvinyl butyral resin and droping the mixture using pippete on to steel surface after sonicating for 2 hours but the final coating gets cracked
