1902 COROZINC M
1K-FH zinc dust primer
COROZINC M is a primer specially designed for use with permanent water exposure (steel hydraulic engineering). Contains 92 % metallic zinc. Moisture-curing zinc dust primers PU are significantly more elastic than conventional 1- and 2-component zinc dust primers. This means, especially with higher coating thicknesses, much higher mechanical resistance. COROZINC M can be painted over with any saponification-resistant 1K or 2K system (no alkyd resins). COROZINC M can also be used as a shop primer.

2004 COROPUR
1K-FH intermediate micaceous iron coating
COROPUR 1K-FH intermediate micaceous iron coating is primarily used, in combination with moisture-curing systems, as an intermediate coating in corrosion protection systems from corrosivity category C3. The special, lamellar structure of the iron mica pigmentation, in combination with the PU binder, results in coatings with excellent water and corrosion resistance. COROPUR can be applied by airless application to vertical surfaces with a dry film thickness of up to 150 µm.

2103 COROPUR Teer
1K-FH tar coating standard
COROPUR Teer is a combination of a moisture-curing (FH) polyisocyanate and tar. COROPUR Teer is, comparable to the usual 2-component epoyy- or polyurethane tar coating materials, particularly suitable for the long-term corrosion protection of all steel surfaces. It is particularly characterized by high abrasion resistance, chemical resistance and low water and water vapour diffusion. Permanent temperature resistant: 60 °C up to a maximum of 80 °C

2003 COROPUR
1K-FH finishing coating silky gloss
COROPUR is a moisture-curing, light, weather and chemical resistant top coat based on polyurethane resin. COROPUR can be applied at low temperatures and high humidity without any problems. The rapid drying and hardening of the coating film allows the coated objects to be manipulated quickly, thus reducing downtimes.

1K-FH finishing micaceous iron coating
COROPUR LS 1K-FH finishing micaceous iron coating serves primarily, in combination with moisture-curing systems, as a high-quality top coat. The special, lamellar structure of the iron mica pigmentation, in combination with the PU binder, results in coatings with excellent water and corrosion resistance. COROPUR LS can be applied by airless application to vertical surfaces with a dry film thickness of up to 150 µm.

1611 ECLON EP
2K-micaceous iron
ECLON EP 2K-micaceous iron is a high-quality scale armour coating with high mechanical and chemical resistance. Dry film thicknesses of up to 150 µm can be achieved in a single pass. The pigmentation with micaceous iron ore creates a rough surface in addition to the barrier effect desired in corrosion protection. The best prerequisite for a perfectly adhering PU-based top coat.

2014 CORODUR FLEX 80
2K-PUA intermediate coating
CORODUR FLEX 80 s a wear protection, absorption, traction and torsion layer. The coating is characterized by very high abrasion resistance (BAW certificate). This applies to dry and wet loads. In combination with Hardener A-2528 for 2K-CORODUR FLEX 80 or Hardener H5 wall for 2K-CORODUR FLEX 80, layer thicknesses of up to 500 μm can be achieved in one application by brushing or rolling. In combination with the fast recoatability, wear protection coatings several millimetres thick can be applied efficiently without special coating equipment, even in unfavourable weather conditions.
The product is available with two different hardeners:
Hardener A-2528
Standard hardener for use as a wear protection coating.Available in white and light gray (tinting is possible for larger requirements).
CORODUR Hardener H5 range
Hardener with increased hardness and better resistance to various chemicals.Available in various colors for coating floors (self-leveling) or walls (thixotropic). The self-levelling setting is also available "antibacterial" and thus reduces the existing germ count on the surface by > 99 % (according to test method JIS Z 2801 certified by Testlabor Dr. Lehmann GmbH, Germany).

2101 COROPUR NonAbrasive
2K-FH finishing coating
COROPUR NonAbrasive is a tough elastic, highly abrasion resistant coating material. Particularly suitable for internal coating and thus long-term corrosion protection of pressure pipes and other steel surfaces. COROPUR NonAbrasive is characterized by low water and water vapor diffusion. Allows thick layer application up to 400 µm even on vertical surfaces. Gloss and UV-resistant coatings are achieved with the correspondingly resistant variant COROPUR NonAbrasive 2K-FH finishing coating LS.

2102 COROPUR Teer 21
2K-FH tar coating
COROPUR Teer 21 is an extremely fast-drying, moisture-curing polyurethane in combination with coal tar and micaceous iron ore. Particularly suitable as a thick-layer top coat on primed substrates. As a single layer, i.e. without primer for medium-heavy corrosion protection such as for shipbuilding, industry in immersion or underwater applications (for a long functional life). pH range 5–10.
