PRIMING FOR FLUOROPLASTIC COATING Russian patent published in 1995 - IPC

Abstract RU 2049102 C1

FIELD: coating application. SUBSTANCE: priming has an aqueous suspension of polytetrafluoroethylene and an aqueous solution of aluminophosphate or aluminochromophosphate binder with phosphate modulus from 1.6 to 2.4 at mass content of polytetrafluoroethylene in composition from 50% to 90% metalphosphate binder from 10% to 50% (measured as anhydrous substances). Priming is applied on the cleansed metal surface, dried, heated at temperature sufficient for metalphosphate binder hardening (200-380 C), then a layer of pure polytetrafluoroethylene is applied, dried and coating is caked at 360-380 C. EFFECT: high adhesion of coating obtained to metal surface, resistance in boiling water.
