Description / Abstract:
The material defined by this specification is a solvent free
sealer based on butyl rubber. It is die cut from extruded,
laminated sheeting, spot weldable, heat curing, and heat meltable.
It has pressure sensitive adhesive on one side covered by release
paper or foil. The other side is covered by a very thin PE support
film for handling. After curing this film does not interfere with
the adhesion of the butyl sealer to the metal surface.
