Lewatit® K 2629 is a strongly acidic, macroporous, polymer-based resin in spherical bead form, with sulfonic acid groups. It is ideally suited as a heterogeneous catalyst for organic reactions and for the processing of aqueous and organic liquids.

A large pore structure, high capacity and a high degree of crosslinking, enable this catalyst to be used in polar and non-polar media.

It is very compact and thus of exceptional mechanical stability.
