Product Data Sheet

Sikaflex®-715 is a one-component, silane-terminated polymer (STP) roof sealant engineered for sealing RV roofs, roof membranes, and open joints exposed to demanding outdoor conditions. Its semi self-leveling consistency allows the material to flow smoothly into joints and seams, creating clean, durable seals with minimal tooling required.

Designed specifically for roofing and transportation applications, Sikaflex®-715 provides excellent adhesion to a wide variety of common roofing substrates, including EPDM roof membranes, metals, fiberglass, plastics, and coated surfaces. Its primerless adhesion capabilities help simplify installation while supporting reliable long-term performance.

This moisture-curing sealant offers outstanding UV and weather resistance, making it ideal for exposed roof joints and exterior sealing applications where durability is critical. Unlike many traditional roof sealants, Sikaflex®-715 chemically cures rather than simply drying, helping reduce shrinkage while maintaining flexibility and sealing performance over time.

Sikaflex®-715 is formulated with low VOC content and isocyanate-free chemistry, supporting cleaner application and improved environmental performance. Its excellent dispensing characteristics allow for easy application in both manufacturing and repair environments, making it a dependable solution for RV maintenance, roof repairs, and general roof membrane sealing applications.
