PRESERVE & PROTECT

SRS 4100 Concrete Guard is an advanced vapor-phase corrosion inhibitor that forms a durable protective film on embedded steel, enhancing the tensile strength of concrete. Ideal for combating corrosion, chloride contamination, and carbonation, SRS 4100 ensures long-lasting durability and improved adhesion for bonded materials like FRP and surface coatings.

Product Details

SRS 4100 is a premium vapor-phase corrosion inhibitor designed to strengthen and protect concrete surfaces. This organic, surface-applied solution creates a durable passivating film on the embedded steel, pacifying both anodic and cathodic sites of the corrosion cell. SRS 4100 migrates as vapor to deposit on the embedded steel, providing long-lasting protection.

When To Use

When corrosion is present or suspected.
On chloride-contaminated concrete surfaces.
On concrete surfaces showing signs of carbonation.
