Applications like in civil engineering and marine requires resistance to a variety of corrosive gases, industrial chemicals, humidity, and saline water. The type of resistance can be obtained only if the outside layer maintains its adhesion to the various substrates like aluminum, steel, other metals, and alloys.
The other applications where use of epoxy Resins is wide are in industrial maintenance paints, coatings used for chemical or fertilized plants, coatings used for offshore oil borings engineering, industrial machinery used in heavy duty, shipping yards, pot coatings, boat building facilities, refinery and steel plants, and paints used in road marking etc. Other areas in which it is used are in floor toppings, expansion joint filling systems, crack injection, grouts, wider crack substantial systems, and adhesives.
Though we have seen numerous applications where epoxy resins are used but when we talk about civil engineering, epoxy is the preferred over other materials because it is known to give best performance.
Other added benefits of epoxy resins are as follows-
- Epoxy is available in different viscosities and is widely used in civil engineering applications, adhesives and low VOC coatings.
- It consists of average molecular mass and is available in form of solution to provide ease of handing.
- Other benefits of these resins are that it has very superior chemical and mechanical resistance properties. In addition, they are low in viscosity in comparison to Bisphenol-A based resins.
- Epoxy Resins is a mixture of other various epoxy resins or Reactive Diluents. They are appropriate for applications in civil engineering, laminates, and coatings.
If we talk about reactive type of diluents, then these are the epoxy groups that consist of functional products. When it reacts with the curing agents, becomes main element of the cross-linked epoxy system.
Reactive diluents are used to reduce the viscosity of the base resin in order to get better handling and easy processing in various applications.
The diluents are further divided into three groups namely-
Further, it is divided into three forms based on the functionality
