Construction
For excellent core mechanical strength & specialised advantages
Through the evolution of civilisation, construction remained relevant. Advent of Concrete brought in an impetus to change the future of the Construction. Today, Construction is not just on the forefront of Engineering and Technology but of Art and Artistry as well. It cuts across industries. As each industry advanced, demands on Construction has grown manifold, beyond its traditional role of a structural shell. Protection from corrosion and abrasion, load-bearing, mechanical and chemical resistance, easy maintenance, industry-specific needs like dust-free, anti-slip, anti-static, impermeable, on-the-go, minimum downtime and even aesthetics and artistry.
Economic viability and easy availability makes Concrete, a preferred choice. But it falls short beyond its traditional role. Global green agenda doesn't favour it either. This led to the birth of many alternatives and auxilliary products. Among them Epoxy Resin has emerged as a revolutionary product, completely changing possibilities. Rearranging norms, it has established new benchmarks in quality and performance. It has empowered designers to push creative boundaries, architects to create sans restraint, engineers to optimise outcomes, formulators and applicators to enhance productivity and safety. Most importantly, Epoxy Resins helps businesses innovate and dream bigger. Aditya Birla Advanced Materials has been at the forefront of this evolution. Companies and businesses, across the globe rely on us to achieve their most exacting and innovative needs.
Construction Applications
Epoxy Concrete Primer
The native property of every concrete structure is its porosity. Air is bound to be trapped within the pores. When a self-levelling coating permeates into the concrete, the trapped air will come out leading to tiny pin-holes on the coating surface. At times, viscosity of the self-levelling coating increases due to cross-linking of EP binder. Air from the pores come together and stick under the coating surface weakening its mechanical strength leading to chipping. This is where an Epoxy Concrete Primer system comes in to prevent a protective coating from turning into a non-protective one.
The primary use of an Epoxy Concrete Primer is to close the pores to maximise mechanical strength of the concrete structure. Free of entrapped air, the chemical resistance of the coating remains intact. The next most important use is adhesion of a coating with the concrete substrate. EP binder systems delivers excellent adhesion across different substrates including mineralic ones. Priming then becomes the most vital step of most civil coating applications.
Advantages
- Increases mechanical strength of structure
- Protects the integrity of self-levelling coating
- Eliminates deadhesion of coating from substrate
- Eliminates effort and cost of de-aeration
- Quicker curing time
- Low PHR factor, optimising economic value
- CMR hazard free variants
- Water-based variants for eco-safe applications
Damp tolerant primer for concrete
This is a specialised application in the case of green concrete or concrete in contact with soil, like underground garages. The Epoxy Concrete Primer must withstand pressure of entrapped water from green concrete and reduce pressure of water vapour coming from the soil. For proper adhesion, the Epoxy Concrete Primer system must be applied twice. Two layers are applied at approx. 500 g/m². The first layer is applied without sprinkling sand and for second layer, sand is sprinkled to get a better adhesion with the next layer. Good incorporation of Primer into the surface with a roller applied with pressure, is very critical.
