- Product description
Sikaflex®-221 is a universally applicable, one-component polyurethane adhesive and sealant that reliably cures to an elastic, resistant elastomer when exposed to air humidity. It has a very broad adhesion spectrum and is suitable for durable, elastic sealing and bonding in vehicle construction, trade, caravan/boat building, metal construction and industrial environments. The colour 7012 (similar to RAL 7012 basalt grey) is often used as a special colour for applications in vehicle and car body construction to enable visually matching sealing joints or seam seals.
