Metal Seal Corrosion Prevent Sealant

Metal Pretreatment Sealant & Corrosion Inhibitor | Metal Seal 285

A water-based alkaline sealant for corrosion prevention on phosphated metal surfaces. Metal Seal provides an inhibitive seal on iron, zinc, and manganese phosphated surfaces, boosting corrosion resistance without reducing paint adhesion. Used as a final pretreatment step before painting, it also strips residual soil and phosphate sludge from the surface, leaving a clean, paint-ready substrate with an added layer of corrosion protection.

Key Features

• Provides excellent corrosion resistance on phosphated metal
• Does not reduce paint adhesion — engineered for pre-paint pretreatment
• Removes residual soil and phosphate sludge in the same step
• Effective on iron, zinc, and manganese phosphated surfaces
• Water-based alkaline formula
• Economical — dilutes 25:1 up to 50:1
• Biodegradable

Applications

• Machine shops
• Manufacturing and remanufacturing plants
• Powder and liquid paint facilities
• Metal pretreatment lines prior to painting
• Phosphate coating finishing and sealing operations

Why Choose Metal Seal

• Corrosion Protection: Lays down an inhibitive seal that boosts corrosion resistance on freshly phosphated metal.
• Paint-Ready Finish: Seals without compromising paint adhesion, so downstream coatings bond properly.
• Two Jobs, One Step: Removes leftover soil and phosphate sludge while it seals, streamlining the pretreatment line.
• Broad Compatibility: Works on iron, zinc, and manganese phosphate surfaces alike.
• Economical: Dilutes 25:1 up to 50:1, so a little goes a long way.
• Biodegradable: Water-based chemistry that breaks down rather than persisting in waste streams.
