How is abrasive blasting eliminated by use of Si-COAT?
Si-COAT adheres to the metal via bonds that are much stronger and more numerous than those employed by conventional coatings such as epoxies, alkyds, etc. Because of this fact, Si-COAT can tolerate a surface with greater contamination than can a conventional coating. Hence, abrasive blasting is unnecessary. Furthermore, with conventional coatings, the practice of profiling a metal substrate is frequently employed. The act of profiling deepens the microscopic crevices in the steel’s surface and effectively increases the surface area available for bonding. In doing so, the statistical likelihood that a conventional coating will form a bond with the metal substrate is increased. The chemistry of Si-COAT is superior to that of conventional coatings in that it does not require profiling as an aid to improve adhesion.
