Corrosion Preventative Coating

Lomg-term corrosion prevention in a transparent single component coating

 

CORROSION PROOFER

CPT-201

CPT-201 is a time-proven coating that provides excellent protection to all metal substrates. It leaves a firm film that provides extreme corrosion protection. The film has extreme resistance to salt water and salt spray, making this coating particularly useful in drilling, marine, industrial and offshore corrosion proofing applications. The film dries transparent. CPT-201 provides optimal long-term corrosion protection for ferrous and non-ferrous metals exposed to harsh environments, as it deposits a molecular layer of corrosion inhibitor that creates a durable, long lasting bond. CPT-201 comes in aaersol can format, 5-gal, 55-gal or 278-gal.

Dry Film Thickness mil: 2-3 mil (50-75 m)
Dry Time: 30 min.
VOC g/l (lbs/gal): 190 grams per liter
Solids %: 55
Coverage ft 2 /gal (m 2 /l): 300 (7.4)
Application Method: Spray, dip, roll, brush
Topcoatability: Yes
Length of Protection: 5 years

Dry-to-touch film properties allow protected metal surfaces to be easily handled.

  1. No surface preparation, as it will adhere to the pre-rusted, oily and dirty surfaces.
  2. A thixotropic liquid; self-healing; resistant to sag, run-off and flow.
  3. Excellent U.V. resistance, providing optimal outdoor protection without cracking or chipping after prolonged exposures to sunlight.
  4. Universal protection for ferrous and non-ferrous metals and alloys.
  5. The non-conductive film with high resistivity and insulating properties effectively prevents galvanic corrosion between dissimilar metals.
  6. Has moisture-displacing characteristics and penetrating film characteristics
  7. Thermally stable over a broad range of temperatures.
