Hand Lay-Up & Spray Gun Lamination

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

ANDONOX KP-LE is a methyl ethyl ketone peroxide (MEKP) with higher content of free hydrogen peroxide (H2O2) to provide shorter gel time then the ANDONOX KP-9. It is suitable for hand lay-up, spray-up, RTM, continuous laminating, centrifugal casting, filament winding, polyester concrete and vacuum infusion.

NOROX MEKP-9H is a methyl ethyl ketone peroxide which features a reduced level of hydrogen peroxide compared to Andonox KP - 9 and gives a longer gel time when workshop and resin temperatures increase during warm weather.

NOROX MEKP - 925H is specifically formulated to reduce gas generation in critical corrosion applications for vinyl ester resins in gel coats, barrier coatings, and corrosion resistant structures.

Norox MEKP-925 has a high MEKP dimer content that gives excellent performance in most vinyl ester resins.

Norox MEKP-900 is a specially formulated methyl ethyl ketone peroxide (MEKP) composition for the room temperature cure of unsaturated polyester resins.

Norox MEKP-30 provides more accurate metering control in hot weather or with highly reactive resin systems and is an excellent liquid initiator for the polymerization of vinyl monomers and is particularly useful in the room temperature cure of polyester resins.

Norox MEKP-9 is an excellent general-purpose methyl ethyl ketone peroxide (MEKP) type cure initiator for the room temperature cure of polyester resins.  MEKP-9 provides medium to high exotherm characteristics to the cure.
