Description of Sikaflex 15 LM Elastomeric Sealant

Scroll to Pricing

Formulated to be used with moving joints or where high movement capabilities are needed, the Sikaflex-15 LM is a low-modulus, 1-component, polyurethane-based elastomeric sealant. This sealant has a joint movement of +100% / -50%, making it perfect for wall systems, around windows and door frames, high-rise and facade applications.

Sikaflex 15 LM has great adhesion properties, so bonding to most construction materials without a primer is possible. After curing, the non-sag sealant is paintable using water, oil, and rubber based paints to match surrounding materials.

Meets Federal Specification:
TT-S-00230C, Type II, Class A
ASTM C-920, Type S, Grade NS, Class 100/50, use T, NT, G, M

Federal Specification for silicones:
