New 1C Tunnel Coating

Newly developed by MC-Bauchemie, MC-Color T 21 has been launched as the first single-component (1C) coating on the market capable of fulfilling the surface protection requirements of ÖBV, ASTRA and ZTV-ING Part 5 Tunnel, as well as those specified for OS 2 and OS 4 systems.

In no way inferior to two-component coatings based on reactive resins, also offers improved light yield with an optimum gloss level, simplified and faster cleaning, a reduction in operating costs, greater resilience and very good environmental compatibility. It also meets all requirements in terms of fire behaviour.

MC-Color T 21 Combines Advantages of 2C and 1C Products

The new tunnel coating consists of a water-based, one-component acrylate dispersion, which is available in different colour shades. It combines the advantages of a 2C product with those of a 1C product. The MC-Color T 21 coating, which can be applied by roller or airless spraying, is very resistant and long-lasting. In addition, the long mixing, repotting, and remixing steps common with 2C products are no longer necessary, which considerably reduces the amount of work. While 2C products must be processed and used immediately, once opened containers of MC-Color T 21 can be resealed and reused later.

Benefiting from an innovative single-component 3D binder technology, the system creates very dense, highly robust surfaces offering long service lifetimes. The coated surfaces are UV and weather resistant, making them colour-stable with a zero tendency towards yellowing. They absorb little dirt, are easy to clean and are very resistant and scratch-proof.

MC-Color T 21 is water-repellent as well as water-impermeable and offers a high level of protection against carbonation. Since the coating is also resistant to temperature, freeze/thaw cycling and de-icing salts, it can also be used in the spray and splash zone exposed to those de-icing salts.

1C Tunnel Coating Provides Better Lighting Conditions in the Tunnel

With a gloss level of 40–60 according to DIN EN ISO 2813 and a reflection value LRV of ≥ 70, which corresponds to class 70 according to the BS 8493 standard, MC-Color T 21 ensures excellent lighting conditions in tunnels. This allows tunnel operators a more economical use of light and high energy efficiency in the operation of the structure.
