• Advanced Chemical Base: Utilizes Silane Terminated Polymer (STP) chemistry for superior elasticity and long-term durability, outperforming traditional sealants.
• Semi Self-Leveling Formula: Engineered to flow just enough to conform to surface irregularities, bridging gaps and covering fasteners around roof components like skylights, vents, and antennas for a smooth, even finish.
• Primerless Adhesion: Achieves strong, reliable bonds to difficult substrates, including EPDM, TPO, anodized and bare aluminum, steel, metal primers, 2-part coatings, ceramics, and various plastics, simplifying application.
• Exceptional UV Resistance: Maintains its integrity and flexibility under harsh environmental conditions, preventing cracking and ensuring a watertight seal for years.
• Isocyanate-Free & Low VOC: Environmentally responsible and safer for users, with a VOC content of less than 0.5%, virtually eliminating shrinkage and harmful emissions.
• Moisture-Curing Mechanism: Cures reliably upon exposure to atmospheric humidity, transforming into a highly elastic elastomer that retains its shape and flexibility.
• Wide Service Temperature Range: Performs robustly in extreme temperatures from -50°C to 90°C (-58°F to 194°F), ensuring stability across diverse climates.
• High Elasticity: With a Shore A hardness of 10 and 500% elongation at break, this sealant allows for significant substrate movement without compromising the seal.

Sikaflex®-715 is suitable for sealing a wide variety of RV roofing components and open joints, bonding effectively to materials such as EPDM, TPO membranes, anodized and bare aluminum, phosphated, chromated, and zinc-plated steel, as well as various ceramics and plastics. This product is intended for experienced professional users, and it is recommended to perform tests on original substrates to ensure optimal adhesion and material compatibility, especially for materials prone to stress cracking.
