hi members,

Doing a research on the Cold vulcanizing Cement/ Solution (Non Flammable), though not being from the science field but have a keen interest in it, i got stuck for quite a long time on the hardening agent that is to be used for acceleration and plays an important role in binding the Rubber & the object.

Now, the problem here persists is that ,
Is Pourable urethane or polyurethane to be added with "Methylene Chloride and MDI(4,4' - methelenebis)" for the formation of the hardener that is to be used with the vulcanizing Cement/ Solution or else . 
If Polyurethane is to be used, then of what type and what grade & with which solvent ?

ANY HELP ?
