Hardener Luperox K12 G

Luperox® K12 G does not contain methyl ethyl ketone phthalate and peroxide.
In ortho- and isophthalic resins, Luperox® K12 provides long-term gelling and is therefore particularly recommended for the production of very large castings at elevated temperatures in the work area.

Due to its specific formulation and low hydrogen peroxide content, Luperox® K12 G is well suited to cure a wide range of vinyl ester resins without foaming.



Hardener Luperox K3

Luperox ® K3 is an acetyl acetone peroxide used to cure unsaturated polyester resins at room temperature in combination with a cobalt accelerator.
