Single component epoxy based zinc rich primer for steel
CONCRESIVE® ZR is a single component, solvent
borne zinc rich epoxy primer, providing active
galvanic protection to steel. It is a thick grey liquid
of paint-like consistency, recommended for use
where chloride induced attack on steel and
concrete is involved.
• As a protective coating to steel reinforcing bars
• As a touch-up primer for damaged galvanised
• As a primer for steel substrates prior to suitable
components against corrosion.
• Excellent adhesion to steel.
• Easy to use single component material.
• No pot-life restrictions or wastage.
• Short overcoating time.
CONCRESIVE® ZR is a single component system,
supplied in 1 litre units.
