Armor Plate 950 is a 100% solid epoxy putty that is applied to wet or submersible surfaces. Because of its ability to cure underwater and arrest corrosion, AP 950 is used for:

  • drilling rigs
  • bridge abutmets
  • bulkheads
  • well jackets
  • concrete drainage ditches
  • other equipment which cannot be coated and cured in a dry environment

Chemical Resistance

Armor Plate 950 has excellent chemical resistance to both fresh and salt water. Fresh water acts as a solvent to AP 950. Contact the Wil-Cor, Inc. Technical Department for chemical resistance of Armor Plate 950 in specific service conditions.


  • Cures under water
  • Demonstrates excellent resistance to fresh and salt water conditions
  • Variable mixing ratio produces the best flexibility/hardness characteristics for the specified service

Surface Preparation

A clean surface is necessary for proper bonding of the Armor Plate 950. Remove corrosion, dirt, oil and other contaminants. When coating marine surfaces, the surface should be cleaned from the top of the splash zone to two feet below low-tide water level.

Sandblasting, a procedure which works well underwater, is the preferred method for preparing surfaces for the AP 950 application.


The Armor Plate 950 mixing ratio, by volume, is 1 part Resin (part A) to 1 part Cure (part B). The flexibility/hardness characteristics of the coating may be adjusted by using more Cure (part B). More part B causes an increase in flexibility, and a decrease in the coating hardness. DO NOT use more than 1.5 parts Cure to 1 part Resin, as poor bonding will occur under immersion conditions.


Armor Plate 950 coating may be applied by hand trowel, putty knife, or other flat blade. A 1/8 in. to 1/4 in. film thickness will provide adequate protection.

For marine coatings, the best application method is by a person wearing a wet suit, rubber gloves, life jacket, and a life line secured to the structure. A heavy ring of the Armor Plate 950 is applied by hand, above the water line. The coating is then smeared uniformly, using an up and down motion, over the area to be coated. The edges of the coating are feathered when the desired thickness is obtained.


Armor Plate 950 is available in stock sizes of two-gallon and ten-gallon units.
