High-temp binder for gelatine-based coating?
Got a formula, published in the UK in 1970, for an
infrared-pass/visible-block coating intended for flashbulbs, as follows:
Eosin 2524, 60 grains
Tartrazine N. 250, 88 grains
Coomassie Violet RS, 60 grains
Lissamine Green, 146 grains
Gelatin (hard), 200g
I want to use such an IR-block coating on a lighting device that gets and
stays hotter, longer than a flashbulb. Can anyone suggest a binder other
than "Gelatin (hard)"?
