ASI 12SK

HI-FLEX BUTYL SEALANT

SEALS, ADHERES & REMAINS FLEXIBLE

ASI 12SK Butyl Sealant is a one part, butyl-based sealant formulated to perform better than the average butyl by using synthetic fibers for more flexibility, better adhesion and greater versatility.

ASI 12SK provides a long-term seal between all types of masonry, steel, aluminum, glass and other common construction/industrial materials. ASI 12SK Butyl Sealant shows excellent resistance to weathering, bubbling, cracking, and other performance issues usually seen with butyl sealants. ASI 12SK conforms to the requirements of Federal Specification TT-S-01657. It is also paintable when using most industrial and commercial paints.
