Performance thickness ratio at its best

GEOMET^® 720 is applied to protect fasteners and many types of metallic parts from corrosion and is used in many industries. It can be combined with PLUS^® topcoats to provide a very broad range of friction coefficients. It is the reference zinc flake coating in Asian countries. 

• Thin dry-film, non-electrolytic
• Water-based chemistry
• Passivated zinc and aluminium flakes in a binder, patented chemistry
• Chrome free alternative to DACROMET^® 380
• Metallic silver appearance
