Luperox® K12G is a Methyl Ethyl Ketone Peroxide phthalate free. In ortho- and isophthalic resins, Luperox® K12G gives long gel time and is therefore particularly recommended for the manufacture of very large molded pieces when the room temperature is elevated. Thanks to its specific composition and its low content in hydrogen peroxide, Luperox® K12G is well adapted to the cure of a wide variety of vinyl ester resins with no foaming affect.

Typical concentrations for Luperox® K12G are from 1 to 3% by weight based on resin and for cobalt accelerator from 0,25% to 4% based on1% metal content solution. Faster reaction and shorter demold times can be obtained by the addition of promoters such as dimethyl aniline or diethyl aceto-acetamide to the cobalt accelerator.
Luperox® K12G is recommended for the curing of ortho- and isophthalic, Bisphenol-A, neopentyl-glycol or Vinyl Ester resins at temperatures between 15 and 50°C in presence of cobalt accelerator.

Typical applications of Luperox® K12G are:
- Hand lay up,
- Spray up,
- Centrifugal casting and filament winding,
- Polyester concrete,
- Gel coats,
- Curing of vinyl ester resins.
