RPP – MT 500
RPP MT 500 is a redispersible binder based on a copolymer of vinyl acetate and ethylene. It is a hard powder polymer used for modification of mortar and plaster systems which are cement-based with or without lime.
Particularly suitable for use in trowelling, adhesive and composite mortars for composite thermal insulation systems (CTI systems) with rigid polystyrene foam slabs and mineral wool slabs, where very good adhesive properties are demanded, in particular after wet storage, as well as good indentation resistance.
