  • Thermally stable nitrocellulose emulsions, solutions and coatings
    Patent number: 5254161
    Abstract: 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.
