In the earlier article, we discussed how Rusticide helps in removal of rust from steel. Now once the corrosion (rust) has been treated using Rusticide, it is necessary to prevent it from rusting thereafter to ensure that the structure can meet its designed service life.

Sunanda Global has exactly developed a tailormade ready-to-use product - POLYALK FIXOPRIME. POLYALK FIXOPRIME is a chemical that is highly alkaline, polymeric, elastomeric and specially designed to protect steel against corrosion by the mechanism of passivation.

USES

In new Reinforced concrete structures as a coating for reinforcement bars.
Passivation of exposed steel in the repair of structural members.
ADVANTAGES

One-pack system. It can be simply mixed with cement forming a highly alkaline co-matrix.

The high alkalinity of cement fortified by high alkalinity, high flexural strength, and extra adhesion owing to specially engineered polymers in POLYALK FIXOPRIME, give long-lasting protection against corrosion (rusting) of ...
... steel rebars.
Treatment can be carried out at the site. Being cementitious, Polyalk Fixoprime coated rebars do not suffer the loss of a bond when embedded in concrete, whereas epoxy-coated bars are prone to suffer substantial loss of bond.
STEPS TO USE POLYALK FIXOPRIME

Clean the steel surface with a stiff wire brush to remove loosely held rust particles/ scales.
Apply RUSTICIDE with cotton waste swab as per specification.
Mix 1 Kg of POLYALK FIXOPRIME with 1.25 Kgs of fresh grey cement, using a mechanical stirrer, to form a lump-free slurry
Apply this slurry to the steel rebar surface with a brush taking care to avoid pinholes.
Allow this coat to sit for a minimum of six hours (or preferably till the next day)
Apply a second coat of the slurry carefully and allow this coat to set. Take suitable precautions to avoid pinholes. Make sure that no area is left uncovered.
