not a good idea

Bill Tindall, E.Tn.
Screwing around with deviations from directions when it comes to doing polymer chemistry will result in worse adhesive/finish/whatever properties. The variables to not be messed with are catalyst amounts and in the case of epoxy the ratio of polymer (the epoxy component) to the crosslinking amine (hardener). Short change the cross linker and the result will be less tough, at least.

To slow down polymer chemistry (cure) cool the reaction.

Adding fibers or other strong component (thickener) can improve strength. Think fiberglass reinforced epoxy for a boat. At the optimum ratio the strength is determined by the additives strength and the epoxy becomes the binder.

The interaction of all these variables can be complex and lead to changes in the cured polymer properties for better or worse.
