Sol-Gel Coatings Market Is Expected to Grow at a CAGR of 1.9% During 2019-2024
A sol is a dispersion of the solid particles (~ 0.1-1 m) in a liquid where only the Brownian motions suspend the particles. A gel is a state where both liquid and solid are dispersed in each other, which presents a solid network containing liquid components. The sol-gel coating process usually consists of 4 steps:
(1) The desired colloidal particles once dispersed in a liquid to form a sol.
(2) The deposition of sol solution produces the coatings on the...
