Mipa PU 420 (1 kg) is a high-grade polyurethane-based seam and joint sealant specifically developed for brush application. It creates a permanently elastic, tough, and protective seal that accurately recreates OEM brushed seam textures in automotive body repair.
Designed to deliver exceptional adhesion to various substrates, Mipa PU 420 seals overlap joints and weld seams effectively against moisture, road salt, and corrosion.
Key Features & Benefits:
- Easy Brush Application: Formulated for smooth spreading with a stiff brush to duplicate factory-applied seams.
- Superior Adhesion: Bonds directly to bare sheet metal, zinc-coated/galvanized steel, aluminum, primed surfaces, and sanded OEM coatings.
- Permanently Flexible: Cures to a durable, elastomeric layer that resists cracking under body flex and temperature shifts.
- Overpaintable: Can be safely topcoated with standard 1K and 2K paint systems once fully cured.
- Corrosion Barrier: Provides complete airtight and watertight protection for critical structural seams.
Applications:
- Sealing welded seams in engine bays, trunk compartments, and floor pans.
- Recreating factory brushed seam profiles on wheel arches, shock towers, and sills.
