562C.12 Metal building, butyl tape

Description

562 is compounded to meet pre-engineered metal building specifications. The material is soft, resilient and easily worked by hand, yet adheres instantly to most uncleaned surfaces. 562 has excellent weathering characteristics while retaining adhesion and elasticity in both hot and cold environments. Material should be tested prior to application.

Application

Spacer cubes can be incorporated (562C.12) to prevent bottoming out of sealant when fasteners are
installed. They also prevent sealant from pumping out of the joint due to thermal expansion and contraction of roof panels. 562 has outstanding webbing and elongation properties along with excellent adhesion to glass, plastic (but not plasticized PVC), polyethylene, galvanized aluminum, galvalume, siliconized polyester, polyurethane and polyvinyl fluoride painted substrates. Preformed butyl tapes allow the erector precise control of volume and sealant placement on roof laps, end laps and side laps of metal buildings.

562 is chemically inert and is non-corrosive to paint, metal, aluminum, copper, plastic and will not swell rubber.
