Description
Sika Primer 210 is a solvent-based adhesion primer used before applying Sikaflex adhesives and selected Sikasil sealants on metal and certain plastic bond faces. Shops reach for it when they need a thin, fast-drying pretreatment that helps aluminum, steel, non-ferrous metals, and paint-primed substrates present a more reliable bonding surface before sealant or adhesive application.
Key Features and Benefits
- One-component solvent-based epoxy solution, ready to apply with no mixing step.
- Colorless to slightly yellow film keeps the bond face easy to inspect.
- Fast flash-off supports efficient prep flow before adhesive application.
- Useful on many metals, including aluminum, steel, and non-ferrous substrates.
- Can also support adhesion for selected Sikasil products where recommended by Sika.
- 250 ml can suits service work, prototype builds, and controlled production prep.
Common Applications for Sika Primer 210
- Prepping aluminum and galvanized metal before Sikaflex bonding.
- Surface treatment on paint-primed parts used in transportation and industrial assembly.
- Bond-face prep for metal trim, panels, housings, and fabricated components.
- Sealant adhesion work on approved substrates in industrial glazing and enclosure builds.
- Repair and maintenance jobs that need a compact primer can on hand.
Compatible Substrates and Application Methods
- Aluminum, steel, and many non-ferrous metals.
- Selected plastics and paint-primed surfaces after compatibility testing.
- Applied by brush, felt, lint-free cloth, or foam applicator.
- Best results depend on clean, dry, oil-free surfaces and a single dense coat.
