Zinc silicate properties
Is it possible to make a Zinc epoxy with Zinc silicate properties?
It is a well-known fact that zinc silicate primers outperform traditional zinc epoxy primers in corrosion protection performance and especially in case of damages and under rusting.
Adhesion and cohesion- Adhesion: Zinc silicates have better adhesion to the steel surface. A chemical bonding to the steel surface compared with zinc epoxy which has "mechanical" adhesion.
- Cohesion: Zinc silicates are normally pigmented higher by volume than epoxy. Practically this gives more “binder” in the zinc epoxy than in the zinc silicate. And cohesion strength will naturally be better for a zinc epoxy than for a zinc silicate.
Traditional zinc epoxy shows an adhesion break to the steel surface.
Barrier Plus shows a cohesion break similar to zinc silicates leaving zinc pigments on the steel surface. This again will improve protection in damages and corrosion spread from damages.
"Conductive binders"- A key feature of a zinc silicate is the chemical bonding to the surface.
- The higher pigmentation by volume gives also better contact between the zinc particles in the paint film and to the steel surface. The silicate binder itself is not “conductive”.
- By measuring the impedance of epoxy binders, it is possible to find the best solution.
The in-house binder technology used in Barrier Plus outperforms traditional previous used binders.
