Polymer-Bonded Coloured Smoke Compositions

Abstract

Polymer-bonded smoke compositions offers numerous advantages over conventional pressed smoke mixtures such as improved mechanical properties and safety in handling. The Defense Research Establishment Valcartier (DREV) has developed pour-castable coloured smoke compositions using a well known hydroxy-terminated polybutadiene prepolymer cured with a commercially available diisocyanate. These smoke formulations consist of ingredients typically found in pressed powder mix, but dispersed in a polymeric binder. A granulated dye is utilized to provide the low viscosities required for pour-casting. The necessary ingredients and processing techniques as well as the properties and inherent advantages of such compositions are described.
