PEROXAN CU-40 M
Hydroperoxide / Polymerization / Curing / Crosslinking
PEROXAN CU-40 M is used for the curing of vinylester resins in combination with cobalt accelerator.
PEROXAN CU-40 M can successfully be used instead of generally applied ketone peroxides like PEROXAN ME-50 LA 3 X with the following features:
- No "gassing" after the peroxide is mixed in the preaccelerated viylester resin. This phenomenon is very often recognized as a disadvantage of the ketone peroxides in vinylester resins.
- The use of an amine accelerator is in general not necessary to achieve a good cure.
- A fast cure in thin coatings and laminates up to a thickness of approx. 6 mm
- A low peak exotherm in thick laminates
Depending on working conditions, the following peroxide and accelerator dosage levels are recommended:
PEROXAN CU-40 M: 2,0 to 3,0 phr
PERGAQUICK C12 X (Cobalt, 1%): 0,5 to 3,0 phr
Please refer to the material safety data sheet (MSDS) for information concerning safe storage, use and handling of PEROXAN CU-40 M. This information should be thoroughly reviewed prior to acceptance of this product. The MSDS is available for downloading at www.pergan.com or through contacting Pergan directly.
