Puraflex 40 Sealant is a high-modulus, high-performance polyurethane sealant and adhesive designed for demanding construction, engineering, and automotive bonding applications. Formulated to provide exceptional mechanical strength and elasticity, it cures upon exposure to atmospheric moisture to form a tough, durable, yet flexible rubber seal.

Engineered for superior adhesion to a vast array of building materials and metal substrates, Puraflex 40 exhibits outstanding resistance to weather, water, vibration, and impact. Its non-sag consistency makes it ideal for vertical floor joints, body panel sealing, structural expansion jointing, and perimeter sealing across industrial environments.

Key Performance Benefits

• High-Modulus Polyurethane Formula: Combines structural bonding strength with high movement capability to absorb joint dynamic strain and severe impact.
• Superior Multi-Substrate Adhesion: Bonds tenaciously to concrete, brickwork, metals, timber, glass, ceramics, and fiberglass without requiring priming on most surfaces.
• Vibration & Impact Resistant: Flexible elastomer matrix dampens mechanical vibration, noise, and structural expansion cycles without cracking or delaminating.
• Weather & Water Resistant: Excellent resistance to rain, seawater, UV exposure, dilute chemicals, and thermal fluctuations for long-lasting exterior seals.
• Overpaintable Sealant: Once fully cured, the surface can be painted over with most water-based and synthetic paint systems.
• Non-Sag Thixotropic Gel: Heavy-bodied paste applies cleanly without slumping or running in vertical or overhead joint configurations.
