Abstract
A heat resistant protective barrier has one or more layers (1) each comprising a support medium in the form of a plurality of closely spaced-apart strands (2) and a heat actuated and resistive intumescent coating (3) on the strands. The support medium preferably comprises an expanded metal mesh (5").
Claims18
A heat resistant and protective barrier having at least one layer, said at least one layer comprising:
- a free and unattached carrier substrate in the form of a sheet material having a plurality of spaced-apart strands defining therebetween a plurality of apertures, and a heat actuated and resistive intumescent coating disposed on said substrate, said substrate comprising the sole supporting means for said intumescent coating.
A heat resistant and protective barrier having at least one layer, said at least one layer comprising:
- a carrier substrate in the form of a sheet material having a plurality of spaced-apart strands defining therebetween a plurality of apertures, and a heat actuated and resistive intumescent coating disposed on only said strands of said substrate, said apertures between said strands being free of said coating.
A heat resistant and protective barrier, comprising:
- a plurality of layers, each of said layers including a carrier substrate in the form of a sheet material having a plurality of spaced-apart strands defining therebetween a plurality of apertures, and a heat actuated and resistive intumescent coating disposed on said substrate.
A method of forming a heat barrier, said method comprising:
- coating a free and unattached carrier substrate in the form of a sheet material having a plurality of spaced-apart strands defining therebetween a plurality of apertures with a heat actuated and resistive intumescent material, said substrate comprising the sole supporting means for said intumescent coating.
