Thermal curing has the highest share in the market of epoxy curing agents mainly due to its remarkable mechanical strength, high temperature resistance, and permanent durability. It is the most common curing method in high-performance coatings, adhesives, composites, and electronic encapsulation, which is achieved with heat-activated crosslinking for optimal epoxy performance. The automotive, aerospace, and electrical manufacturing sectors appreciate the fact that thermally cured epoxy systems can function at extreme temperatures, as well as tolerate chemical exposure and mechanical stress quite well.
Epoxy properties can be engineered to meet the requirements of specific industries by changing thermal curing agents since they are more flexible as compared to UV and catalytic curing. In addition, thermal curing agents still keep being the primary option in the area of needing high-load capacity adhesives and coatings because of their absorbed strength characteristics and duration.
The trend of UV curing being more and more used is particularly noticeable in such branches as paint and coatings, adhesives, and electronics where the needed factors are fast curing time, low energy consumption, and solvent-free processing. In contrast to thermal curing, which necessitates high temperatures, UV curing instantly polymerizes when exposed to UV light, hence, it results in reduced production time and energy costs.
The paint and coatings sector lies in the fact that it is the predominant consumer of UV-curable epoxy curing agents since it provides high-gloss finishes, exceptional abrasion resistance, and excellent weather ability. Furthermore, it is worth mentioning the use of UV-cured epoxy encapsulates and coatings by the electronics manufacturers to prevent moisture and corrosion that could cause damage to the circuit boards, sensors, and microchips.
Due to the environmental laws forcing industries to seek out alternatives to VOCs (volatile organic compounds), the introduction of UV-curing epoxy agents is, in turn, catalysing the application of these agents in sustainable manufacturing and the development of eco-friendly products.
The paint and coatings industry, which is the largest market segment and thus consumes most of the epoxy curing agents, is majorly used in the application area.
