Thermally stable nitrocellulose emulsions, solutions and coatings

Emulsions, solutions and coatings comprising nitrocellulose are stabilized against yellowing on thermal aging when treated with boric acid or borax or hydrogen peroxide or 0.1 to 0.5% by weight of a chlorinated hydantoin such as 1,3-dichloro 5,5-dimethylhydantoin (DCH). Boric acid or borax may be ad...

Beschreibung
Zusammenfassung:	Emulsions, solutions and coatings comprising nitrocellulose are stabilized against yellowing on thermal aging when treated with boric acid or borax or hydrogen peroxide or 0.1 to 0.5% by weight of a chlorinated hydantoin such as 1,3-dichloro 5,5-dimethylhydantoin (DCH). Boric acid or borax may be added as aqueous solutions during nitrocellulose manufacture. Combined treatments and/or additions of boric acid and DCH give optimum stabilization against yellowing.
