Gelcoat is material useful in protecting structural laminates, which is a fiber-reinforced composite applied to provide a superior finishing. For manufacturing gel coats, isophthalic acid-based resins are used. Isophthalic acid-based gel coats are famous for their water retention and blister resistance properties. Gel coats are handy in decreasing weight and enhancing the fuel efficiency of the transport systems like autos, railways, and leisure vehicles. These gel coats are available in varied thickness and could be applied through brush as well as spray, so they are not susceptible to any cracking. The global demand for gel coats is expected to rise as it is widely used in industries like transportation, wind energy, marine, construction, and others.
