MELAMINE- AND BLOWING AGENT-FREE INTUMESCENT COMPOSITIONS CONTAINING GALLOYL MOIETIES

An intumescent coating composition consisting of a binder system and a two-component intumescent package is described. Tannic acid (TA) and ammonium polyphosphate (APP) have exhibited sufficient characteristics to serve as char formers (via TA), blowing agents (via TA), and an acid source (via APP)....

Beschreibung
Zusammenfassung:	An intumescent coating composition consisting of a binder system and a two-component intumescent package is described. Tannic acid (TA) and ammonium polyphosphate (APP) have exhibited sufficient characteristics to serve as char formers (via TA), blowing agents (via TA), and an acid source (via APP). Such compositions may be incorporated in epoxy and other resin-based coatings. The resulting composition should provide comparable intumescent performance in comparison to existing/available products.
