Project Description

ISO 12944-6: Paints and varnishes — Corrosion protection of steel structures by protective paint systems
The ISO 12944 standard is intended to assist engineers and corrosion experts in adopting best practice in corrosion protection of structural steel with coatings at new construction and repairs. ISO 12944 is progressively superseding regional standards to become a truly global benchmark in corrosion control.

The ZINGA/Zingatarfree system has been subjected to extensive testing such as water condensation
test, neutral salt spray test, chemical resistance test and water immersion test. After a prescribed exposure test (depending on respresentative environment), the coating is assessed for adhesion, blistering, rusting, cracking and flaking.

Environments are classified according corrosivity for structures in immersion:
• Im1: Clear, fresh or potable water
• Im2: Sea or brackish water (harbors with locks, jetties, offshore structures; make sure there is no stray
• Im3: Soil (underground storage, iron poles)

After exposure, the coating is evaluated as H(igh), M(edium) or L(ow); reflecting in a life expectancy of:
Low: Life expectancy less than 5 years
Medium: Life expectancy between 5 and 15 years
High: Life expectancy more than 15 years

The system

ZINGA 1 x 60-80 µm DFT


Zingatarfree 2 x 100 µm DFT

passed the tests for Im2 and Im3 with a High Classification.
