Architectural concrete Cement Bond23 www.denber-paints.co.il
A special acrylic polymer additive for construction. An acrylic polymer additive for cementitious mixtures for GRC architectural concrete , which improves the adhesiveness, flexibility, workability, strength, abrasion resistance, resistance to chemicals and salts and the sealing of the concrete and enables a smooth and decorative finish. Creates a significant improvement in the strength of the concrete and reduces the ratio between water and cement in the cement mixtures, thereby improving its density and strength, reducing the chance of cracking. The sealing prevents the ingress of water that damages the rebar, causing it to rust and the concrete to swell. Prevents accelerated weathering of the concrete and extends its life. Gives a developer time to harden which allows the processing of the material to obtain a dense, bubble-free, smooth and decorative finish.
Features :
- Connects to cement mixtures and becomes an integral part of them.
- Improves adhesion, sealing, workability, strength, flexibility and resistance to chemicals and salts.
- Reduces the water-cement ratio without harming the workability and creates concrete with a higher density and strength.
- Odorless, water-based, easy to apply.
- Transparent and does not change the texture of the concrete.
- Improves the adhesion of adhesives used to glue tiles of all types.
- Improves durability from water penetration into the concrete which creates the crumbling of the concrete and the rusting of the ferric iron which swells in contact with water and explodes the concrete.
- and improves resistance near the sea that is attacked by airborne sailors. Improves resistance to fluorescence.
Uses:
- Acrylic additive for architectural concrete.
