I've a loctite 330 kit which came with adhesive (have some left.) and a single-use break-open capsule of activator which is long gone.

From what I can tell, the adhesive is
Tetrahydrofurfuryl methacrylate 30 - 60%
Chlorosulphonated polyethylene 10 - 30%
Methacrylic acid 5 - 10%
2-Ethylhexyl methacrylate 5 - 10%
Epichlorohydrin-4,4'-isopropylidene diphenol resin 1 - 5%
Talc 0.1 - 1%

the activator is #7387 and the TDS says:
Chemical Type Substituted dihydropyridine
Solvent n-Heptane and Isopropanol

Heptane 30 - 60%
Diethyl-1,2-dihydro-1-phenyl-2-propylpyridine 10 - 30%
Propanol 10 - 30
ethyl-2-propylquinoline 1 - 5%

Would a 90-95% Heptane activator (from a 2-part glue package from the hardware store) effectively work with the 330's adhesive?
