Epoxy antistatic topcoat PRASPAN® EP-C301 AS

Praspan® EP-C301 AS topcoat is a two-component conductive self-leveling colored epoxy system for antistatic polymer floor coatings. It does not contain volatile solvents and is odorless. The surface appearance of the finished floor is semi-matte.

The material is used in rooms and workshops of industrial facilities where static electricity is not acceptable or where enhanced requirements are imposed on electrical safety, cleanliness and fire safety. Antistatic polymer floor coverings are recommended for:

• data processing and computing centers;
• server rooms and telephone exchanges;
• television and radio studios;
• medical facilities with high-precision equipment.

Key properties:

• conductive properties – resistance to earth (EN 1081) <10⁶ Ω;
• excellent resistance to abrasive loads (for example, intensive traffic);
• good chemical resistance to non-concentrated alkalis and acids;
• no odor during and after application, which is especially important when working in residential areas.

The Praspan® EP-C301 AS kit includes:

• topcoat component – 16.86 kg;
• hardener – 5.68 kg.

Kit mass: 22.54 kg.

The material is an opaque viscous liquid without foreign inclusions, in colors from gray to black. Sedimentation of the filler is possible; it must be thoroughly mixed before use.

Material consumption at a 2 mm layer thickness: 2.7 kg per 1 m².

Attention! Due to the presence of special conductive additives in the polymer material, the color of the finished coating may differ from the agreed RAL color.

Crystallization of epoxy-resin-based materials

All produced materials (topcoats, primers, paints) that contain epoxy resins can harden (crystallize) during transportation or storage at subzero temperatures or under temperature fluctuations.

Crystallization is partial or complete solidification of the material. This is a normal phenomenon that does not degrade the epoxy resin and does not affect the material properties.

To decrystallize the material, it must be kept at a temperature of 40°C to 60°C for at least 2–3 hours. Since the decrystallization process at the job site is often difficult or impossible, it is strongly recommended to store and transport all epoxy products at positive temperatures in the range from +5°C to +30°C.
