Bleser AP Blue #20
Never use with chlorate mixtures, even if chlorate is in a separate layer not in contact with the AP mixture. Failure to do so could result in formation of extremely sensitive ammonium chlorate, resulting in spontaneous combustion or explosion.
When rolled in combination with nitrate mixtures, a moisture protection barrier must be created using 4 – 6% NC lacquer as the spray. Difficult to ignite at fast speeds and must use at least 1/32in AP prime as first fire. If bound with water, dry times longer than normal.
