Catalysts
Catalysts, also called hardeners in the industry, are needed to cure polyester and vinyl ester resins. If you need special catalysts, please contact us. We are happy to help you find the best solution for your project. Romar-Voss Composites offers the following catalysts in its standard range.
Peroxan ME-50 LX
Methyl ethyl ketone peroxide for general use
Solution in TXIB
Cures in combination with a cobalt accelerator for the curing of unsaturated polyester resins, gelcoats & topcoats
Provides foaming in vinyl ester resins
Peroxan ME-50 LA3 X
Methyl ethyl ketone peroxide
Dissolution in TXIB
For curing cobalt-pre-accelerated polyester resins and vinylester resins
Longer processing time in polyester compared to ME 50-LX (standard MEKP)
Standard hardener for vinyl ester resins (no foaming)
Peroxan ME-50 LU 2 X
Mixture of Methyl ethyl ketone peroxide and Cumene hydroperoxide
Solution with plasticiser
Used in combination with cobalt pre-accelerated polyester resins
Low peak exotherm
Suitable for curing thick laminates and casting compounds
Peroxan A-40 L
Acetylacetone peroxide
Solution in diacetone alcohol
For curing cobalt-pre-accelerated polyester resins
Provides faster curing than ME-50 LX catalyst at equal processing time
Peroxan CU-40 M
Cumyl hydroperoxide
44%, solution in promoter
For curing of cobalt-pre-accelerated vinyl ester resins
No gas formation after incorporation into vinyl ester resins
Low peak exotherm
Provides medium to fast curing for laminates up to 6 mm thick
Peroxan CU-80 L
Cumyl hydroperoxide
80% solution in cumene
For curing unsaturated vinyl ester resins
Low peak exotherm
Provides long processing times in cobalt-pre-accelerated resins
Peroxan BP powder 50 W
Dibenzoyl peroxide
50% powder in dicyclohexyl phthalate
For curing amine-pre-accelerated polyester resins
Dissolves quickly
Very fast curing
Works from 5°C
