What are Epoxy Resins to Repair Structures


The epoxy is a kind of resins popularly and widely used in engineering application as well as other resins like acrylic, polyester, polyurethane and other similar types. These resins mostly used in repair work like grouting of cracks in the concrete structures, in repairing the eroded concrete structures, in emergency repair of bridges, repair of aqueducts, in repairing the chemically eroded columns and beams etc. Contact the Deco Polymer concrete repairfor repairing the eroded and cracks in your concrete structure.

When the epoxy resin gets cured by a different type of hardeners, they offer a wide range of properties. The basic characteristics of epoxy are properties that are highly adhesive and have the strength for almost all the materials, while curing epoxy has low or no shrinkages, has natural gap filling properties, has higher resistance to various types of environments along with chemicals, and the epoxy can cure in wet condition for example it cures in underwater construction. One of the significant aspectsof epoxy resin is it can be applied very easily without any complications.

The epoxy resin happens to be a generic terminology representing various types of thermosetting polymers. The epoxy resin is produced from its raw material called epichlorohydrin. The DGEBA or the Diglycidyl Ether of Bisphenol-A is the specific epoxy resin which is widely used in the construction industry. Eventually, the DGEBA is the condensation outcome or product of epichlorohydrin and Bisphenol-A in its standard form. The epoxy resin’s molecular weight ranges from high to low based on the quantity of epichlorohydrin to Bisphenol-A. Ultimately the basic resin of these types is not suitable for use in many applications due to its higher viscosity.

Therefore, the base resin modification needs to be essential for achieving the needed curing ratio. The hardeners which are actually curing agents are combined with the epoxy resin which hardens the epoxy resin from its liquid form. Among many hardeners, the most popular hardeners are the aromatic and aliphatic amines and polyamides. These hardeners can actively harden the epoxy resin at room temperature and are considered best for construction.

Modification of resin is essential to bring about certain physical and chemical change in the resin. The use of modifiers like rubber, thermoplastic, diluents, flame retarders, pigments and dyes, and fillers modifies the epoxy resin. This modification of resin makes it crack and fatigue resistant, and flexible. Similarly, pigments and dyes are responsible for providing a resin variety of colours.
