SQ CERAMIC - Protective coating
10x improved resistance to corrosion
compared to galvanising 5 μm
WHAT IS SQ CERAMIC??
SQ Ceramic lamellar coating application technology is the modern way of protection against corrosion. Lamellar coating application technology properties are also used in the automotive and aerospace industries.
The coating consists of a mix of zinc and aluminium flakes, and binding resins. The lamellar coating is characterised by exceptionally effective protection against corrosion despite a relatively thin layer.
This ensures 10-time higher protection against corrosion in relation to zinc plating and 2-time higher protection in relation to hot-dip galvanizing (HDG).
The lamellar coating maintains resistance to red corrosion even up to 1000 hours in the salted atmosphere chamber while hot-dip galvanizing only 500 hours. The coating has also high resistance to chemicals and UV radiation but does not contain heavy metals, including hexavalent chromium (VI).
