Abstract
Corrosion on industrial infrastructures can be prevented or arrested using a multi-stage system and method having an optional epoxy primer, a thermoplastic layer, a self-amalgamating water-cure wrap, and a top coat of epoxy. The resulting impervious barrier resists corrosion and withstands abuse from the elements.
Claims11
A barrier system for infrastructure including:
- A) A thermoplastic having an inhibition monolayer bound directly to an encapsulation region, and an outer skin monolayer in direct contact with said inhibition monolayer;
- B) A wrap layer bound directly to said outer skin monolayer, said wrap layer a moisture cured tape;
- and
- C) An epoxy layer bound directly to said wrap layer, wherein said barrier system is impervious.
1 more element
An impervious bolting assembly including:
- A) A bolt including low alloy steel;
- B) A thermoplastic including an outer skin monolayer substantially surrounding exposed portions of said bolt, said thermoplastic including a sprayable liquid having a hardening point of 110-130° C.;
- C) A moisture cured tape in direct contact with said outer skin monolayer and having a shore hardness of approximately 83 when cured;
- and
- D) An epoxy substantially surrounding and in direct contact with said thermoplastic.
