TEKNOPRIME 840 is a two-component primer designed for application to steel reinforcement to protect against corrosion. The primer is impregnated with corrosion inhibitors, which react with the surface of the reinforcement to produce a passivating layer, prior to the application of PREMCRETE REPAIR MORTARS. TEKNOPRIME 840 exhibits excellent adhesion to the steel and is alkaline in nature which protects the steel from chlorides and water to prevent corrosion.
TEKNOPRIME 840 is used as a steel reinforcement primer prior to the application of subsequent repair mortars and coatings.
• Excellent adhesion to steel reinforcement.
• Flexible once cured to provide long lasting protection.
