C-Pure Self-Leveling Seam Sealer is a two-part polyurethane adhesive and sealant engineered for OEM-style seam sealing and structural bonding. Its self-leveling formulation eliminates manual spreading while providing consistent coverage across trunk seams, drip rails, roof seams, and core supports. The material delivers Shore D 40 hardness with 90% elongation for flexible, crack-resistant performance under vibration and thermal expansion. It features a 15-minute working time, 30-minute paint readiness, 1-hour bonding time, and full cure within 12 hours, with 15,000 mPa·s mixed viscosity and 1.08 relative density.
Instructions
Clean and degrease the surface thoroughly.
Abrade the bonding area to improve adhesion.
Mix and apply using a manual or pneumatic dispenser.
Allow the material to self-level without manual spreading.
Let cure fully before heavy load or stress.
Applications
Automotive seam sealing for trunks, roofs, and drip rails
We use this self-leveling seam sealer for trunk seams, drip rails, and roof seam repairs. It flows out evenly without much tooling, stays flexible after cure, and can be painted fairly quickly, which helps keep body shop jobs moving. Love it!
