Anti-carbonation acrylic system comprises a single component penetrating silane-siloxan primer and a single component elastomeric pigmented coating, both ready for immediate site use.
Anti-carbonation acrylic system is an elastomeric, water based protective coating based on a special acrylic polymer. It provides excellent elongation and recovery, dirt pick-up resistant, resistance to aggressive elements, UV light and rain. Because of its resistance to pick up dirt and easy to clean properties; the AC441 will reflect most of the sun rays resulting in cooler structures (when using colour white). It is available in a wide range of colors.
Uses
To protect atmospherically exposed reinforced concrete structures from attack by acid gases, chloride ions, oxygen and water, where there is a danger of subsequent cracks appearing within the substrate.
Suitable to protect all types of structures, cementitious substrates, masonry and aggressive marine and coastal environments.
Protection against exhaust fumes - Carparks.
Advantages
Can accommodate substrate cracking up to 2mm and cyclic movement up to 0.3mm.
Excellent barrier to carbon dioxide, chloride ions, oxygen and water.
True elastomeric coating with excellent elongation and recovery properties.
Allows water vapour to escape from the structure.
UV resistant with high resistance to the effects of long term weathering.
Fast dry, it can be recoated within 2 hours thus reducing dirt pick up and down-time.
