Epoxy Curing Agents are amine-based chemicals which when reacted with epoxy resin create a three- dimensional cross-linked system that can be formulated with exceptional performance properties making them ideally suited for use in a wide range of industrial applications. Various kinds of curing agents are available for epoxy resins. Among these agents are amine functional dispersion technology and water-soluble curing agents on Mannich base. Both of these methods are commercially viable and provide pure compounds for curing epoxy resins. Moreover, they are compatible with conventional epoxy resins and greatly reduce the yield of char. They are commonly used in aerospace and automotive applications.
Moreover, these curing agents can be used for coatings as well as primers. Epoxy Curing Agents have good recoat-ability and mechanical properties. Moreover, these agents provide excellent corrosion protection. Furthermore, they can be used to create durable surfaces and protect them against wear & tear. However, curing agents must be used correctly to avoid causing problems. If not, they will cause a malfunction or damage to the coating. Water-based curing agents are also available. They have low viscosity and are compatible with cement. These properties make them more flexible in formulation development. They can be used for primers and transparent epoxy coatings. These solutions are gaining popularity in the protective coating market. In addition, they are more environmentally friendly than solvent-borne systems. However, the development of new curing agents should take into consideration limitations and requirements of specific products and applications. When it comes to applying an epoxy coating, a variety of curing agents are available. Some are widely used in construction and building maintenance applications, while others are used for decorative and/or protective coatings. Waterborne Epoxy Curing Agents are becoming more popular as they provide improved worker safety and a lower risk of exposure to solvents and other chemicals. This type of curing agent is low-viscous, allowing it to be used in coating systems with low viscosities. These agents have different basicity, molecular structure, and belong to different functional groups. These properties allow Epoxy Curing Agents to control curing reactions and properties of cured thermosets. Epoxy curing are mainly classified as polyamides, aliphatic amines, aromatic amines, catalytic, anhydride, mercaptans, and polysulfide, among others. Each have advantages and dis-advantages over the other and for specific requirements. Characteristics, such as gel time, pot life, viscosity, both chemical and physical properties, and environmental limitations play an important role in the manufacturing of epoxy curing. However, the selection of curing agents is completely depends upon the process and end user requirements. Epoxy curing are also used as a component of polymers, plastics, dyes, polyurethane, coatings, as well as additives to paints. Ethylene Glycol has many useful chemical properties, including resistance to heat, mechanical & electrical stability, solubility, photoconductivity, friction, biological applications, among others. Curing agents are added to resins to harden or toughen them. However, the choice depends on the base resin as well as the required degree of toughness. Epoxy Curing Agents are widely used in composite, adhesives, metal coatings, and concrete coatings. They offer properties such as chemical strength, electrical insulation, and mechanical strength. Thus, there is an increasing demand for epoxy curing worldwide.
