Abstract
Polymer-bonded smoke compositions offers numerous advantages over conventional pressed smoke mixtures such as improved mechanical properties and safety in handling. The Defence Research Establishment Valcartier (DREV) has developed pour-castable coloured smoke compositions using a well known hydroxy-terminated polybutadiene prepolymer cured with a commercially available disocyanate. 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 pourcasting. The necessary ingredients and processing techniques as well as the properties and inherent advantages of such compositions are described.
