WC-1 (ICE) General Description

This Modified Fluoropolyurethane is a two component solvent-based topcoat. It combines the advanced technology of Fluoropolyol Resin, PTFE, Fluoroalkylsilane and Dimethyl Siloxane into a thin film coating system applicable to a variety of properly prepared substrates. This modified combination of materials, when cured, forms an extremely low surface energy film that creates a difficult surface for ice to adhere to. The finished cured system displays exceptional moisture and abrasion resistance while providing corrosion protection with outstanding appearance.

WC-1-ICE Modified Fluoropolyurethane is not a sacrificial coating; it expels no toxic chemicals into the surrounding atmosphere. It also exhibits excellent weathering characteristics and color retention with exceptional UV resistance for extended service life.

Additional Performance Data of WC-1-ICE FPU ICE Release Coating

The following test information was compiled through a cooperative research and development agreement with the Department of the Army, Corps of Engineers Cold Regions Research and Engineering Laboratory, Hanover, NH. The testing was performed on solid aluminum billets approximately 3" long by 1" diameter. The coated samples were washed with isopropyl alcohol, placed into molds with distilled and de-aired water and placed in the cold room at -40�F for three days. Following are the tests results of the samples derived from using the Zero-Degree-Cone apparatus.

Surface Preparation

Good surface preparation and cleaning of the substrate is essential to the performance of the coating system. All the surfaces that are to be coated should be dry, clean, and free of all contaminants.

Limitations:

Abrasive blast for this coating system. The relative humidity must remain below 85%. Apply coatings only when the surface temperature is more than 5° F above the dew point temperature of the surrounding air. This 5° F differential is necessary to prevent condensation of moisture on the surface. Apply this coating system only when the temperature of the ambient air and the receiving surface is between 50° F and 90° F. For optimum application properties, the temperature of the stored material should be between 50° F and 80° F prior to mixing and application. Maintain the unmixed material in closed containers in protected storage at 40° F to 100°F and out of direct sunlight or rain.

Ferrous Metal

Abrasive blast steel to SSPC-SP 6 to SSPC-SP 10 "Commercial Blast" to "Near White Metal Blast" with a surface profile of 1.5 to 2 mils (25 to 50 microns). On old or previously finished surfaces the degree of cleaning required prior to blast cleaning is dependent upon the condition of the substrate. Remove oil and prime with Pretreatment (Wash) Primer such as DOD-P-15328D, F-117 or equivalent.

Brush apply one coat of primer (Epoxy Polyamide Primer 21EP150 or equivalent) over welds, corners and crevices.

Apply full coat of primer (21EP150) over entire area to 3.0 mils DFT upon completion of the brushed areas. Apply primer to all areas as soon as possible after blasting but not longer than eight hours. Check dry film thickness. All areas must have a minimum coating of 3.0 mils DFT of primer. Areas with less than 3.0 mils DFT of primer should have an additional coat of primer or intermediate applied. Some specifications will require two (2) coats of primer / intermediate at 2 to 4 mils DFT each to assure proper coverage, with a total DFT of primer / intermediate to be 4 to 8 mils.

Apply the WC-1 Fluorinated Polyurethane at 2.0 to 3.0 mils DFT to obtain a total Dry Film Thickness of the coating system of 5.0 to 8.0 mils.

Galvanized Metal

Remove oil and prime with Pretreatment (Wash) Primer such as DOD-P-15328D, F-117 or equivalent.

Aluminum

Clean thoroughly and etch with phosphoric acid based cleaning solution. Rinse well and allow to dry. Prime with 21EP150 or equivalent.

Concrete

Must be clean, dry, properly cured and free from all surface contaminants. "Brush off Blast" (SSPC-SP 7) to provide an etched surface and to remove contaminants and laitance. Remove all dust before coating.

Prime with an Acrylic Block Filler, if surface is extremely porous, or with an Acrylic Primer, if relatively smooth. Allow to dry at least 48 hours.

Follow primer with an intermediate coat of Epoxy Polyamide 21EP151 or equivalent prior to finish.

Fiberglass

Must be clean, dry, properly cured and free from all surface contaminants. Hand or mechanically sand entire surface until smooth and to remove any gloss.

Solvent wipe surface with MAK, MIBK, MEK or Acetone, turning rag continuously to remove all sanding dust. Repeat if necessary to assure a clean dry surface.

Apply 1 or 2 coats of Epoxy Polyamide primer or intermediate (21EP150 or 21EP151) or equivalent prior to finish.

Mixing

This is a two component coating supplied in two separate containers: Component A (base) and Component B (activator). Thoroughly mix Component A (base) with mechanical agitation material prior to mixing. Lightly shake Component B (activator) prior to mixing. Pour contents of Component B into Component A while under light agitation and stir well for approximately 3 to 5 minutes prior to application. No induction time is required, just thorough mixing of the materials. The paint should be kept covered at all times after mixing and during application to prevent contamination. Note that this material is moisture sensitive. Any introduction of moisture or water into the material during mixing or application will shorten usable pot life drastically.

Thinning

This product, when mixed, should be ready to apply. In the field, it should require minimal thinning for application. If thinning is necessary to achieve the desired application viscosity, thin up to approximately 10 percent, maximum, per gallon. Use only the thinners indicated above in the Specification section.

Application

WC-1 is designed for spray application but small areas may be brushed. Use of an airless spray unit, conventional spray or HVLP spray is recommended. No special system for cleaning or repairing is required. Steel surfaces should be abrasive blasted and primed. It is desirable to limit the area blasted to allow the application of the primer coat during the same shift. No longer than eight (8) hours should elapse prior to the application of the prime coat.
