Zinc by nature offers the best possible protection to corrosion.
SigmaZinc 158 has galvanic action properties, thus eliminating sub film corrosion. It is a two-component ethyl silicate system with a balanced zinc-level, containing enough zinc particles to live up to the performance that may be expected from a relatively zinc-rich primer.
It equally complies with a wide number of environmental legislations and has a ASTM A490 class Certificate “B” for slip co-efficient.
