Abstract:
INTUMESCENT COMPOSITIONS OF THE INVENTION COMPRISE CERTAIN ARYLSULFONAMIDOPYRIDINES, SUCH AS THE 2-, 3-, AND 4SULFANILAMIDOPYRIDINES. 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 A SUBSTRATE IN ANY SUITABLE MANNER, SUCH AS BY ELECTRODEPOSITION, SPRAYING ONTO AN ADHESIVE SUBSTRATE, OR THE APPLICATION OF A COATING COMPOSITION COMPRISING THE INTUMESCENT AGENT.
Abstract:
Intumescent compositions of the invention comprise certain arylsulfonamidopyrimidines, such as the 2-, 4-, and 5sulfanilamidopyrimidines. 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 electro-deposition, spraying onto an adhesive substrate, or application of a coating composition comprising the intumescent agent.
Abstract:
Intumescent compositions of the invention comprise certain arylsulfonamidopyrazoles and imidazoles, such as 3sulfanilamidopyrazole, 2-sulfanilamidoimidazole, and derivatives thereof. The intumescent agents may be employed in conjunction with additives conventionally used in intumescent compositions. Articles coated with these intumescent compositions are also described.
Abstract:
Intumescent compositions of the invention comprise certain arylsulfonamidopyrazines, such as 2-sulfanilamidopyrazine, 2sulfanilamidobenzopyrazine, and derivatives thereof. The intumescent agents may be employed in conjuction 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:
INTUMESCENT COMPOSITIONS OF THE INVENTION COMPRISE CERTAIN ARYLSULFONAMIDOTHIAZOLES, ISOTHIAZOLES, OXAZOLES, AND ISOXAZOLES, SUCH AS 2-SULFANILAMIDOTHIAZOLE, 5-SULFANILAMIDOISTHIAZOLE, 2-SULFANILAMIDOOXAZOLE, 5-SULFANILAMIDOISOXAZOLE, AND DERIVATIVES THEREOF. THE INTUMESCENT AGENTS MAY BE EMPLOYED IN CONJUCTION 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, EACH AS BY ELECTRODEPOSITION, SPRAYING ONTO AN ADHESIVE SUBSTRATE, OR APPLICATION OF A COATING COMPOSITION COMPRISING THE INTUMESCENT AGENT.
Abstract:
The invention relates to a process for protecting substrates with intumescent compositions comprising certain arylsulfonylureas, such as p-amino-benzenesulfonylurea, paminobenzenesulfonylthiourea, etc. The intumescent agents may be employed in conjunction with additives conventionally used in intumescent compositions.
Abstract:
Coated articles of the invention are substrates coated with intumescent compositions which comprise certain nitrogencontaining aromatic sulfones, thiosulfonates, and sulfonates. Exemplary of the intumescent agents are bis(p-aminophenyl) sulfone, 1,2-bis (4-acetamidophenylsulfonyl)ethane, p,p''diacetamidophenylthiosulfonate, and p,p''-diaminophenylsulfonate.
Abstract:
Non-flaming intumescent compositions are obtained by mixing a normally self-extinguishing intumescent agent with an amine having a nitrogen or combined nitrogen-halogen content of at least about 30% by weight. The amine may be aliphatic, aromatic, or heterocyclic but is preferably melamaine, a melamine derivative, or other cyclic compound.
Abstract:
Intumescent compositions of the invention comprise certain N4thiazolyl, isothiazolyl, oxazolyl, and isoxazolyl aminoarylsulfonamides, such as N4-2-thiazolylsulfanilamide, N4-5isothiazolylsulfanilamide, N4-2-oxazolylsulfanilamide, N4-5isoxazolylsulfanilamide, 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:
Intumescent compositions of the invention comprise certain N4pyridylaminoarylsulfonamides, such as the N4-2-, 3-, and 4pyridylsulfanilamides. 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.
