Abstract
Electroless metal coatings of increased adhesion are obtained on nitrocelose base explosive films, grains, etc., by incorporating ammonium perchlorate in the nitrocellulose explosive substrate to be electrolessly coated with the metal.
Claims12
In a method for producing a metal coating on a nitrocellulose base propellant substrate, wherein the metal is deposited on the nitrocellulose substrate from an electroless metal plating bath, the improvement which comprises incorporating in the nitrocellulose substrate to be coated an effective amount of a particulate ammonium perchlorate to increase the adhesion of the metal coating produced.
A method of conditioning a nitrocellulose base propellant substrate to increase the adhesion of an electrolessly deposited metal coating thereon, which comprises incorporating in the nitrocellulose substrate to be coated an effective amount therefor of a particulate ammonium perchlorate.
