SEI Corrosion Proof™ Coat

The SEI Corrosion Proof Coat utilizes CPT™Technology (Corrosion Preventative Technology). This is a highly charged and durable migrational molecule that has the ability to penetrate and travel through a wide variety of mediums in order to find and bond with all types of metal. The CPT molecule needs to fulfill its ionic attraction by bonding with either ferrous or non-ferrous metal. Once the CPT molecule has found metal it creates a highly durable, resilient and robust chemical bond. This bond provides extensive protection for long periods of time in very harsh environments. SEI Corrosion Proof Coat is a brown thixotropic coating. It comes in oil based or solvent-based carriers. The residual film, after solvent evaporation has extreme resistance to salt water and salt spray, making SEI Corrosion Proof Coat particularly useful in marine, industrial, and off-shore corrosion proofing applications. The film dries semi-clear and transparent. SEI Corrosion Proof Coat provides optimal long-term corrosion protection, for ferrous and non-ferrous metals exposed to harsh environments.

Advantages

Dry to touch film properties allow protected metal surfaces to be easily handled.
No surface preparation, as SEI Corrosion Proof Coat will adhere to the pre-rusted, oily and dirty surfaces.
A thixotropic liquid, self-healing, resistant to sag, run-off, and flow.
Excellent U.V. resistance, providing optimal outdoor protection without cracking or chipping of protective films after prolonged exposures to sunlight.
Universal protection for ferrous and non-ferrous metals and alloys.
The non-conductive film with high resistivity and insulating properties effectively prevents galvanic corrosion between dissimilar metals.
Has moisture-displacing characteristics and penetrating film characteristics
Thermally stable coatings over a broad range of temperature.
Applicable to the following specifications: MIL-C-0083933A and MIL-C-16173D
