Excellent cure initiator for both unsaturated polyester resins and vinyl ester resins.

MEKP-925 FRED is formulated to be an excellent cure initiator for both unsaturated polyester resins and vinyl ester resins. With most unsaturated polyesters, it gives longer gel and gel to cure times, but with a higher peak exotherm than Norox MEKP-9, particularly in thick sections.

Norox 500 is used as a polymerization initiator. It can also be used as a cross-linking agent for various olefinic polymers or co-polymers as well as a vulcanizing agent for synthetic rubbers and a high temperature curing agent for unsaturated polyester resins.

Norox FS-100/9 is primarily used in highly filled resin systems. It is not recommended for gel coats or vinyl ester resins.

Norox 771 is an excellent liquid polymerization initiator for the room temperature cure of unsaturated polyester and vinyl ester resins, when a low peak exotherm is desired.

Norox TBPB is a highly efficient source of free radicals at moderate to high temperatures and can be used as a polymerization or co-polymerization initiator to produce polyethylene, polystyrene and polyacrylates.

Norox W-60 works well in any application where high amounts of water are present. Combining fast gel times with moderate cure profiles, it is not recommended for gel coats.

As a tertiary alkyl hydroperoxide, NOROX TBHP is a convenient source of free radicals for the polymerization of vinyl monomers when the presence of water can be tolerated.

It is an effective medium temperature initiator for the polymerization and/or crosslinking of numerous monomers and resins, including unsaturated polyester and vinyl ester resins.
