Abstract:
1. INTUMESCENT COMPOSITIONS OF THE INVENTION COMPRISE CERTAIN N4-TRIAZOLYLAMINOARYLSULFONAMIDES, SUCH AS THE N4TRIAZOLYLSULFANILAMIDES AND DERIVATIVES THEREOF. THE INTUMESCENT AGENTS MAY BE EMPLOYED IN CONJUNCTION WITH ADDITIVES CONVENTIONALLY USED IN INTUMESCENT COMPOSITIONS. FOR USE IN PROTECTING SUBSTRATES FROM HEAT AND FIRE, THE INTUMESCENT COMPOSITIONS MAY BE APPLIED IN ANY SUITABLE MANNER, SUCH AS BY ELECTRODEPOSITION, SPRAYING ONTO AN ADHESIVE SUBSTRATE, OR APPLICATION OF A COATING COMPOSITION COMPRISING THE INTUMESCENT AGENT.
Abstract:
Intumescent compositions of the invention comprise certain N4pyrazylaminoarylsulfonamides, such as N4-2-pyrazylsulfanilamide and derivatives thereof. The intumescent agents may be employed in conjunction with additives conventionally used in intumescent compositions. For use in protecting substrates from heat and fire, the intumescent compositions may be applied to the substrate in any suitable manner, such as by electrodeposition, spraying onto an adhesive substrate, or application of a coating composition comprising the intumescent agent.
Abstract:
A process for protecting a substrate from heat and fire with an intumescent composition which comprises sulfaguanidine, i.e., paminobenzenesulfonylguanidine, as the intumescent agent. The sulfaguanidine may be employed in conjunction with additives conventionally used in intumescent compositions.
Abstract:
Intumescent compositions of the invention comprise certain arylsulfonamidothiadiazoles and oxadiazoles, such as 2sulfanilamido-1,3,4-thiadiazole, 3-sulfanilamido-1,2,4-oxadiazole and derivatives thereof. The intumescent agents may be employed in conjunction with additives conventionally used in intumescent compositions. For use in protecting substrates from heat and fire, the intumescent compositions may be applied to the substrates in any suitable manner, such as by electrodeposition, spraying onto an adhesive substrate, or application of a coating composition comprising the intumescent agent.
Abstract:
