Abstract
A sealant strip is provided having a soft, resilient synthetic foamed resin core, preferably having a pressure sensitive adhesive coating on at least one of two of the opposed sides of the core and thin preferably silicone rubber sealing layers cured in situ on the two remaining surfaces of the core. The strip is adapted for adhesive attachment to and compression between structural members, with the core supporting the edges of the sealing layers in contact with the opposed surfaces of the structural elements between which the strip has been compressed.
Claims14
A strip adapted to be used for sealing a joint between two abutting structural elements comprising a core of foamed synthetic resin that is resilient and elastic, and which includes on two sides thereof, a high performance cured flexible coating that is impervious to water and air, and at least one of remaining two sides being coated with a pressure sensitive adhesive layer.
A sealant strip adapted to be used for sealing a joint between two abutting structural elements comprising a core of foamed resilient polyurethane having a rectangular cross section, two opposite sides of said sealant strip being coated with a pressure sensitive adhesive, and the remaining two sides of the sealant strip having a thin layer of a cured silicone rubber thereon.
A sealed joint between two opposed edges of adjacent structural elements comprising a generally rectangularly shaped sealant strip compressed between the opposed edges of said elements in a manner to leave two sides of the strip exposed, pressure sensitive adhesive layers on opposite sides lengthwise of said strip which sides are engaged by said edges for bonding the strip to each of said opposed edges leaving said two sides exposed, each of said exposed sides having a thin, resilient layer in the form of a high performance cured coating thereon that is impervious to water and air, and said impervious layer being in contact with the opposed edges of said elements.
