Sika Galvashield T2, Self-Powered Hybrid Anode System, Interior & Exterior, 20 units

Sika Galvashield T2 is a second generation hybrid anode system used to control corrosion in reinforced concrete structures. Sika Galvashield T2 is a Type 2 anode for embedment within drilled holes in sound concrete. Sika Galvashield T2 combines the high level performance of an impressed current electrochemical treatment system with the longterm maintenance-free capabilities of an alkali-activated galvanic cathodic prevention system. The single-unit system does not require complex wiring or an external DC power supply (temporary or permanent). When installed, the inbuilt impressed current component provides an initial phase of high charge density that passivates active corrosion (Phase 1). Then, the anode automatically switches to a cathodic prevention phase, which maintains steel passivity and provides longterm, maintenance-free corrosion protection (Phase 2). The anode spacing and parameters of pre-treatment are customised by Vector Corrosion Technologies based upon the specific condition of the structure and are in conformance with the principals of ISO BS EN 12696:2016.
