Sika Sikaflex 15LM is a low-modulus, high-performance, 1- component, polyurethane-based, non-sag elastomeric sealant. Excellent for moving joints in vertical applications. Exceptional sealant choice for high-rise and facade applications where high movement capability is required.
High elasticity – cures to a tough, durable, flexible consistency with exceptional cut and tear resistance
Very good adhesion – bonds to most construction materials without a primer
