| 摘要 |
Intumescent compositions of the invention comprise certain arylsulfonamidothiadiazoles and oxadiazoles, such as 2-sulfanilamido-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.
