For conditions C4

ARMEPOX® DTM 243 Mastic ALU

Two‑component epoxy putty with aluminum pigment, forming a protective coating in the color “Aluminum Grey”. It can be applied to partially prepared surfaces and exhibits high tolerance to insufficient surface preparation (remaining rust and old coatings). It is used for repair painting and in conditions where high‑quality surface preparation cannot be ensured. The aluminum pigment enhances the coating’s barrier properties and provides additional protection against moisture and corrosion.

FAQ

What does the abbreviation “Corrosion activity conditions C4” mean?

International standard ISO12944 "Coatings. Protection steel structures from corrosion using coating systems" in its second part classifies environmental conditions into 6 categories based on their corrosive effect. Category C4 corresponds to high. Under such conditions, metal (in particular steel) is subject to a significant risk of rapid corrosion wear, therefore strict anticorrosion protection is required. Typically, this refers to industrial areas with high humidity and pollution, or coastal zones with moderate salinity.

Do you have coating systems for C4 conditions?

Yes, we can offer several systems to choose from based on service conditions. System for conditions without UV exposure: 1*180 µm ARMEPOX 243 mastic. For conditions with UV exposure, 1*180 µm ARMEPOX 243 + 60 µm ARMOPUR DTM 162. Service life from 7 to 15 years.

Which category of standard SN 2.01.07‑2020 “PROTECTION OF BUILDING STRUCTURES FROM CORROSION” corresponds to category C4 ISO 12944?

Category C4 corresponds to environment class HA2. (Table 37. CH.2.01.07.-2020).
