Paints & Coatings Carbonation Protection Coatings with Dual Function
Construction chemicals are one of the important sectors in the chemical industry. It is used for various reasons with the main objective being - protection. Anti carbonation coating is one such solution that protects concretes in the building from pollutants and harsh weather.
The main objective of exterior paint is not just to decorate but also to protect the concrete structure. In the past, the latter objective was often neglected and as a result, paints were not vapor permeable.
In such a case, the paint would peel off in humid weather. This scenario has changed these days with the help of anti carbonation coating. This is a type of protective coating which is devised to provide long term protective and decorative properties to concrete and stonework surfaces.
Coatings Protect Concrete Structures From Carbonation and Water
Anti carbonation coatings are used to Source: Remmers India improve the life of concrete structures like flyovers, bridges, roads etc. It makes the structure or building waterproof and provides it with the ability to resist even wind driven rain. Additionally, it also helps protect the architectural coatings against chloride penetration and allows water vapor diffusion.
The coatings also do the job of making the buildings carbonation resistant and attain high UV resistant qualities while making it look attractive. The coating features microporous structure that acts as a barrier to the ingress of chlorides and carbon dioxide and other acid gases while allowing the passage of water vapor from the concrete structure.
The elastomeric nature of the coating ensures good crack bridging properties, in case of structural movement and also protects the existing concrete from water, carbon dioxide, sulphur dioxide, oxides of nitrogen, chlorides, sulphates and other pollutants. Apart from the concrete, protection of steel, which is encased in the concrete, is also equally important as it is the backbone of any structure.
