EmceColor-flex is an acrylic polymer modified elastic elastomeric breathable, anti-carbonation, crack bridging, and UV resistant protective coating for new or strained concrete surfaces, against environmental pollution, notes a press release from MC-Bauchemie (I) Pvt Ltd, (mc-bauchemie.com) manufacturers of this product. It is based on acrylic polymers and selected mineral fillers. Emcecolor-flex is water based and solvent free, therefore eco-friendly. It provides excellent protection for concrete subjected to adverse climatic conditions like in cooling towers, chimneys, bridges, buildings, etc., the press release notes.

The product is waterproof and has a low water vapor diffusion coefficient. This makes the coating breathable. It also has a high resistance to diffusion of carbon dioxide and thus has anti-carbonation properties. In addition, EmceColor-flex is crack bridging, which is advantageous in case of repair and protection of cracked facades, exhibiting hairline and shrinkage cracks (within the region of 0.2 mm crack width). Its UV resistance ensures no fading or degradation of coating material.

EmceColor-flex can then be applied in two coats, using painting rollers, brushes or by airless spraying over a primer coat of Primex 250. More coats offer higher degree of protection and better crack bridging properties. This product is fully compatible with fully solvent free PCC system for the protection, repairs and maintenance of concrete structures. The consumption of Primex 250 is approximately 100 gm/m² and that of EmceColor-flex is approximately 425 to 450 gm/m² in two coats for a thickness of 200 - 225 microns.
