PURfect Silicone – 722 is a premium, low-modulus sealant and adhesive. It performs exceptionally well in both weather sealing and structural glazing applications. This neutral-cure, high-performance silicone is incredibly versatile. It bonds strongly and stays flexible over time.
Additionally, it adheres to a wide variety of substrates. These include polycarbonate, PVC, glass, vinyl, fluoropolymer and powder-coated paints, aluminum, stainless steel, galvanized steel, ceramic tile, wood, FRP, marble, stone, EIFS, brick, and laminate.
Because it’s made from 100% silicone, PURfect Silcone – 722 allows up to 50% joint movement. It handles both extension and compression with ease. This flexibility ensures strong, durable seals even in high-movement areas. Moreover, it maintains excellent recovery after cycling.
Importantly, PURfect Silicone – 722 resists UV exposure, ozone, temperature swings, and moisture. This makes it ideal for tough outdoor conditions.
Beyond performance, it’s also user-friendly. It applies smoothly and leaves a clean finish.
Finally, it meets or exceeds key performance standards, including:
ASTM C920 Type S, Grade NS, Class 50, Use A, G, M, O
ASTM C1184 Structural Silicone Sealants Type S, Use G & O
U.S. Federal Specs TT-S-001543A and TT-S-00230C
CGSB-19.13-M87 (Canadian General Standards Board)
