Tacky Tape® SM5227 is a highly elastic butyl tape with excellent surface tack specifically designed for sealing metal roof panel joints and Standing Seam Roof (SSR) endlaps. Its superior surface tack allows it to adhere to metal substrates that are contaminated with light roll forming oil without prewiping the surface. It has excellent adhesion and compressibility to cold substrates. It is formulated without asbestos fillers.
PRODUCT DETAILS
Tacky Tape® SM5227 is 100% solids, asbestos-free butyl tape sealant that is a highly rubbery, tacky, reinforced compound designed for sealing metal lap joints in the metal building industry. It is easy to apply and compress during installation. It exhibits excellent application and performance characteristics over a wide temperature range and will not become brittle, crack or flow during service. It is available in various sizes supplied in ready-to-use rolls and pre-cut end lap pads for standing seam roof (SSR) applications. It is also available in double and triple bead rolls and end lap pads.

How To Install
Tacky Tape requires no tools for installation. It comes in an easy-to-handle roll and the adhesive is quickly exposed with a simple peel-back.
APPLICATION
Optimally, a clean dry uncontaminated surface is desired to obtain intimate adhesion, but realistically there are field situations that prevent complete control of surface conditions.
Obviously, excessive oil, caked-on dirt, free standing water and ice or snow must be removed before sealant tape is applied.
This sealant tape can be applied in cold temperatures. Temperatures below 40°F (4.44°C) often promote the formation of condensation and frost substrates. These should be removed
before the sealant tape is applied in order to achieve optimum performance. Remove condensation and other moisture with a clean dry cloth and isopropyl (IPA) alcohol. Follow this with a dry cloth wipe.
A light film of lubricant used in roll forming is usually present on unpainted surfaces, such as Galvalume and should not adversely affect the sealant tape performance. If excess lubricant is
present wiping with a clean cloth should minimize it.
Position tape sealant on required seal area with release backing paper on top. The tape sealant should be positioned on the “wet”, or entry sides of the fasteners to prevent passage of dynamic weather elements. Using a smooth even hand motion; press the tape to the surface to make intimate contact without distorting the tape sealant. Avoid lapping the tape by butt joining tapes at transition points. Remove release-backing paper prior to mating adjoining surface and fastening. IF SEALANT TAPE IS IN DIRECT CONTACT WITH ANY OTHER SEALANT OR ELASTOMER, A COMPATIBILITY TEST MUST BE CONDUCTED PRIOR TO USE.
