General Solubility Information

The following is a listing of available materials that are (among other things) used as a binder in pyrotechnic type formulations. Those so marked with
" * " preceding the item indicate that the material so used in solution, that is to say, it is dissolved in the appropriate solvent before mixing into the formulae. It should be noted that all of these materials may be used in solution but those so noted must be dissolved first because of their more difficult to solvise properties. Do not allow complete solvation before evaporation and drying the mixture resulting in adhesive bond failure. Some of these materials may take as long as 24 hours at room temperature to completely dissolve.
If maximum strength is required, binder solutions should be used instead of moistening the dry mixture containing the binder. A solution allows a more thorough, homogenous mixing with adequate wet-out and a cured strength many times greater than the same binder when used dry.
Those so indicated with "+" also have good moistureproofing properties (some better than others) because they are impervious to moisture themselves and seal the ingredients in the formula that are hygroscopic from the air and moisture they may otherwise absorb from it.
