LUPEROX K1S E MEKP - phthalate-free hardener for polyester and vinyl ester resins (available sizes: 5 kg, 25 kg)

Phthalate-free hardener for unsaturated polyester resins.

Manufacturer: ARKEMA

Luperox® K1S is methyl ethyl ketone peroxide used to cure unsaturated polyester resins at room temperature in combination with a cobalt accelerator. Luperox® K1S is used in techniques such as hand lay-up, spray-up, centrifugal casting, filament winding, and polyester concrete. It is particularly suitable for curing gel coats. Its low viscosity makes it ideal for spray-up (airless) techniques with external mixing. A faster reaction and shorter mold demolding time can be achieved by adding promoters such as dimethylaniline.
