How does Si-COAT stop rust creep?
Si-COAT is an elastomeric product with elongation up to 180%. If any coating is scuffed down to the steel that it is protecting, the exposed steel will begin to corrode/rust. When steel rusts, the steel expands up to 12 times its initial volume. Conventional coatings are not nearly as elastic as Si-COAT. As exposed steel corrodes and expands next to conventional coatings, the coating is unable to cope with the expanding steel and simply “pops” away from the steel, thus exposing more fresh steel to corrode and expand. This cycle continues and rust then “creeps” under the surface of the conventional coating. Si-COAT, however, is able to conform to the expanding steel. Coupled with Si-COAT’s extremely strong adhesion characteristics, Si-COAT Anti-Corrosion Coating cannot “pop” away from the steel. Si-COAT stops rust creep dead in its tracks. Salt fog chamber tests have revealed that Si-COAT keeps rust creep to under 2 millimeters (under 4/100th’s of an inch).
