Claims20
An ignition-suppressing tape, comprising:
- a backing strip;
- and
- a sealant strip comprising polysulfide material and having a heat resistance of from about 70° F. and about 300° F., and a freeze resistance of between about 45° F. and about −85° F.,
- wherein the sealant strip is disposed on a portion of a first surface of the backing strip;
- wherein the first surface of the backing strip includes a pressure sensitive adhesive;
- and
- wherein a peel strength of the sealant strip after curing is larger than about 20 times greater than a peel strength of the backing strip.
4 more elements
A method of installing an ignition-suppressing tape, comprising:
- cleaning an installation surface, the installation surface includes at least one cut edge and at least one adjacent uncut surface of a polymer panel;
- selecting an ignition-suppressing tape with an appropriate geometry, the ignition-suppressing tape including a backing strip and a sealant strip disposed on a surface of the backing strip, wherein a peel strength of the sealant strip is larger than about 20 times greater than a peel strength of the backing strip, and the sealant strip comprises a polysulfide material that has a heat resistance of between about 70° F. and about 300° F. and a freeze resistance of between about 45° F. and about −85° F.;
- positioning the ignition-suppressing tape onto the installation surface;
- waiting for an uncured sealant in the sealant strip to cure on the installation surface;
- and
- inspecting the installed ignition-suppressing tape.
