Development of residential and commercial often take part in places with harsh environmental conditions, that have been proved to be determining factors for corrosion development.
Even if all quality processes have been strictly followed, aluminum corrosion is likely to develop under the powder coating layer under specific external conditions, such as increased humidity, saline or/and highly polluted atmosphere. This phenomenon is known as filiform corrosion and constitutes one the major issues of the aluminum powder coating industry.
Therefore, filiform corrosion mostly appears in:
- coastal areas
- residential regions with highly polluted atmosphere
- regions where salt is used on roads for snow and ice removal
- near swimming pools where water is chlorinated
