Beschreibung
Zusammenfassung:	An intumescent composition based upon modifications to tannic acid (TA), including certain additives, is contemplated. Such compositions may be incorporated in epoxy and other resin-based coatings. The resulting composition produces a novel, lightweight, and extremely effective intumescent char having a density of 1.5 to 4.0 mg/cm3. L'invention concerne une composition intumescente basée sur des modifications de l'acide tannique (TA), y compris certains additifs. De telles compositions peuvent être incorporées dans des revêtements époxy et d'autres revêtements à base de résine. La composition résultante produit un produit de carbonisation intumescent nouveau, léger et extrêmement efficace ayant une densité de 1,5 à 4,0 mg/cm3.
