The present invention relates to a combination of A and B adhesives (16 and 12 respectively) reacting together through a scrim material (14) in a laminated combination, and wherein the B adhesive (12) has great adherence characteristics to a vinyl nitrile foam (10), and the A adhesive (16) has great adherence characteristics to itself. Thus, a laminate of the A adhesive (16) / scrim (14) / B adhesive (12) to each side of a slit in a vinyl nitrile foam tubular insulation (10), with appropriate release liners (18) covering the outside A adhesive (16), has been found particularly effective. When the release liners (18) are removed and the A adhesives (16) are pressed together, a very strong bond is created closing the slit in the vinyl nitrile foam insulation (10) holding the tubular vinyl nitrile foam (10) in place on the tubular member to be insulated. Normally, this is utilized in an air conditioning application with the piping or tubes running from the compressor to the air conditioning unit, and wherein vinyl nitrile foam insulation has proven to be the best insulation material for this application. |
