Henkel SICOMET® 77 is a high viscosity ethyl cyanoacrylate adhesive designed for bonding porous, absorbent, and vertical surfaces. With its gap-filling capability and controlled flow, it provides fast and strong adhesion for plastics, rubbers, metals, wood, ceramics, and leather. Ideal for demanding industrial applications, SICOMET® 77 ensures durability and long lasting performance.
SICOMET® 77 is part of Henkel proven SICOMET® cyanocrylate adhesive line, engineered for high-strength, rapid bonding. Unlike lower-viscosity cyanoacrylates, SICOMET® 77 features a medium-to-high viscosity range, making it excellent for bonding porous or uneven substrates without wicking.
It cures within seconds upon contact with surface moisture, enabling fast assembly, reduced downtime, and high productivity in industrial and repair settings. Its ability to handle porous materials and gap-filling needs sets it apart from standard cyanoacrylates.
