Sika Everbuild Tecnic Puraflex 25 One-Part Low Modulus Polyurethane Sealant Grey 300ml

Summary

Sika Everbuild Tecnic Puraflex 25 is a one-part, low modulus polyurethane building sealant formulated for professional construction and jointing applications. Supplied in a standard C3 300ml cartridge in grey, it is designed to replace conventional one-part polysulphide sealants across the majority of building and civil engineering sealing tasks. Its flexible, solvent-free formulation delivers durable, weather-resistant joints in both interior and exterior environments.

Features

• One-part polyurethane formula requires no mixing, ready to apply directly from a standard sealant gun.
• Low modulus cure delivers a highly flexible joint that accommodates structural expansion and contraction without failure.
• Bonds to a wide range of building substrates including concrete, brickwork, ceramics, wood, metal, and uPVC.
• Solvent-free and odourless formulation, suitable for use in occupied or poorly ventilated areas.
• Over-paintable once fully cured - a preliminary adhesion test on the specific paint system is recommended.
• Conforms to ISO 11600 Class 25LM and is CE marked to EN15651-1:2012 Type F EXT-INT CC.
• Movement capability of +100% / -50% (ASTM C719), suitable for dynamic expansion and dilation joints.
• Suitable for vertical and horizontal joints in brickwork, stone, and concrete structures.
