DESCRIPTION

KÖSTER CT 121 is a universally applicable, moisture tolerant, solventfree epoxy resin with high adhesion properties and can be used e.g. prior to the application of KÖSTER CT 221 and for the production of concrete protection systems or trafficable surfaces according to the OS-8 system.

KÖSTER CT 121 develops excellent adhesion on mineral substrates and epoxy resins.

Can be used with kiln-dried quartz sand, e.g. as a primer resin, as a scratch coat, as a leveling mortar or as a stand-alone epoxy resin screed. 

For substrates that are permanently exposed to moisture and are to be finished with vapor-proof floors, we recommend one of the KÖSTER VAP 2000 products. 

When used as a binder, KÖSTER CT 121 with kiln-dried quartz sand can also be used to produce a drainage mortar.

AREAS OF APPLICATION

KÖSTER CT 121 is used as a primer for mineral based substrates before applying KÖSTER Epoxy coating and flooring products (after not longer than 48 hours). Mixed with kiln dried quartz sand KÖSTER CT 121 is also used for making trowelable filler material for interior and exterior application for the following application of epoxy and polyurethane coatings. KÖSTER CT 121 is especially suitable as a primer for KÖSTER CT 221 in the KÖSTER OS 8 System. KÖSTER CT 121 as drainage mortar can also be used as a leveling layer for e.g. balconies or terraces.
