Sikaflex® 221 Medium Strength Adhesive Sealant - Gray, 10.1 oz Cart.

Sikaflex-221 is an economical, multi-purpose ahesive sealant with a wide adhesion range. It is ideally used for sealing and simple bonding applications.

This non-sagging, 1-part polyurethane sealant cures on exposure to humidity in the air to form a durable elastomer making permanent elastic seals of medium adhesive strength. It bonds well to a variety of substrates including wood, metals, metal primers and many paint coatings, ceramic materials and plastics.

Sikaflex 221 is resistant to weathering, seawater and ultra-violet radiation.
Its permanent elasticity and medium strength make for relatively easy disassembly should that be necessary; use razor wire as a tool.
