Sikaflex® Purform® is an advanced polyurethane-based elastic sealant engineered for professional sealing, bonding, and joint protection in demanding construction environments. Built with low-emission Purform® polyurethane technology, it delivers superior flexibility, strong adhesion to multiple substrates, and long-term durability under harsh weather conditions.

This sealant is ideal for sealing expansion joints, façade joints, flooring seams, roofing details, and general construction gaps. Its excellent elasticity helps absorb structural movement, preventing cracks, leaks, and premature joint failure.

Designed for both interior and exterior applications, Sikaflex® Purform® supports sustainable construction practices while maintaining high performance and reliability.
