Sherwin-Williams F63TXA9920 Polane T Propellar Gray Polyurethane Enamel - Gallon

Aluminum: Prime with Industrial Wash Primer, P60G2.

Galvanized Steel: Prime with Industrial Wash Primer, P60G2.

Steel or Iron: Remove rust, mill scale, and oxidation products. For best results, treat the surface with a proprietary surface chemical treatment of zinc or iron phosphate to improve corrosion protection. For untreated steel, prime with Industrial Wash Primer, P60G2, for a smoother finish, follow with Polane Primer/Sealer, E65A4. For the best corrosion protection, prime with Catalyzed Epoxy Primer, E61RC22. For treated steel, to improve performance, prime with Polane Primer/Sealer, E65A4.

Plastic: Due to the diverse nature of plastic substrates, a coating or coating system must be tested for acceptable adhesion to the substrate prior to use in production. Reground and recycled plastics along with various fire retardants, flowing agents, mold release agents, and foaming/blowing agents will affect coating adhesion. A filler or primer/barrier coat may be required. Please consult your Sherwin-Williams Chemical Coatings Sales Representative for system recommendations.

Wood (interior only): Must be clean, dry, and finish sanded. Seal with a full coat of Polane SprayFil.

Testing: Due to the wide variety of substrates, surface preparation methods, application methods, and environments, the customer should test the complete system for adhesion and compatibility prior to full scale application.

Typical Application Setups

Reduction: Reduce 33% for smooth coat or as need for texture coat with Polane Reducer R7K69 or R7K84. Polane Reducer R7K69 is photochemically reactive, R7K84 is non-photochemically reactive. Retarder, R7K216, may be used for better flow.

Texture: Allow 5-10 minutes flash off of the smooth coat before applying the texture coat. The texture may be varied by adjusting the atomizing and fluid pressures until the desired texture size is obtained. Lower atomizing pressures give a larger texture pattern. Higher atomizing pressure reduces the texture size.

Conventional Spray pressure feed, smooth or textured coat:

Gun .............................. DeVilbiss MBC
Air Pressure, smooth ............ 40-50 psi
Air pressure, texture ............. 25-30 psi
Fluid Pressure ......................... 8-10 psi
Cap/Tip .......................................765/E

Conventional Spray suction feed, smooth coat only:
Gun .............................. DeVilbiss MBC
Air Pressure .......................... 40-50 psi

Cleanup

Clean tools/equipment immediately after use with Polane Reducer. Follow manufacturer's safety recommendations when using any solvent.

NOTE: Do not exceed the heat distortion temperature of the substrate.

Spatter or texture coat can be applied immediately after flash off of smooth coat. After 7 days, scuff sand to ensure adhesion.

Product Limitations

• Polane Catalyst, V66V27, interior, or V66V29, exterior, must be used to achieve proper performance. Do not vary catalyst ratio which has been established to provide optimum hardness, flexibility, gloss, and chemical resistance.
• Use catalyst V66V27 for interior use. V66V27 will lead to early chalking and gloss loss on exterior exposures. Use V66V29 for exterior use. Polane T catalyzed with V66V29 is not intended for long term exterior exposures, extended exposure to strong sun will lead to chalking, gloss loss, and color fading.
• For applications involving V66V29 catalyst, V66VB11 accelerator may be used to speed up the dry time. Up to 2 ounces of V66VB11 per gallon of the paint component side is recommended.
• Heat shortens pot life. Do not spray hot. Do not pump catalyzed material into circulating systems. Friction heat developed by pumps and circulation will shorten pot life.
• Protect from moisture, water affects pot life and product properties. Store indoors. Do not package Polane coated products in air tight plastic bags unless completely cured. Polane continues to cure for several weeks, the buildup of organic solvents and reaction by-products could cause improper cure and adhesion failure in use.
• Do not apply to wood for exterior use.
• Do not blend with any polyurethane quality except Polane B or T. No other catalyst, colorants, or reducers are recommended because foreign materials, such as alcohols and glycols, destroy performance properties. Do not use lacquer thinners or alcohol-containing solvents.
