S-75 and S-75C ALUMI-CHROME PRIMER

S-75 and S-75C are a zinc chromate vinyl butyral washcoat (sometimes referred to as a wash primer) used as a pretreatment for metal. S-75 and S-75C is applied in a thin transparent coat since an excessive build-up will cause a lack of adhesion. S-75 and S-75C Alumi-Chrome Primer should be topcoated after an hour and never applied when conditions are right for sweating of the metal or when moisture is present, since S-75 and S-75C are moisture sensitive.
