Solid Rocket Motor

  1. Feb 6, 2005 #1
    Hey everyone,

    My friend and I are building a solid rocket motor using the manual "Building Amateur Rockets" from CP Technologies (by John Wickman). I designed the motor (propellant composition below) but am having trouble finding binder and curing agent in Ottawa Canada. The binder is called R45M and curing agent is Mondur MR. If anybody knows of something we can use in place of these that is more common, it would be greatly appreciated. If not then I guess I'll have to order it from the US.

    Propellant Composition:
    68% Ammonium Nitrate
    18% Magnesium Powder
    14% R45M Binder (or alternative)
    The curing agent is not included in the percent composition, rather the amount is determined on top of the propellant composition above.
