General: Substrate should be free of grease, oil, dirt, fingerprints, drawing compounds, any contamination, and surface passivation treatments to ensure optimum adhesion and coating performance properties. Consult a Florida Finishing Representative for additional details.
- Aluminum (untreated): Prime with Industrial Wash Primer, P60G2, or RoHS Compliant Wash Primer, P60G10.
- Galvanized Steel (untreated): Prime with Industrial Wash Primer, P60G2, or RoHS Compliant Wash Primer, P60G10
- 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, or RoHS Compliant Wash Primer, P60G10. 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 Florida Finishing 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.
• 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.
• Gloss will be slightly higher when catalyzed with Polane Catalyst, V66V29.
• 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.
• Do not blend with any colorants other than Phoenix™ Colorants.
• Gloss levels may be adjusted by using F63T1, Polane Flatting Base.
• Excellent appearance over many types of substrates—metal, plastics, and wood
• Air dry or force dry
• Excellent chemical and water resistance
• Excellent adhesion, mar, and abrasion resistance
• Excellent hardness and impact resistance
• Widely used for coating business machines and computers because of resistance to stains, chemicals and abrasion and for long-term durability.
• Texturing minimizes surface irregularities and provides a three dimensional appearance
• Available in a broad range of colors
• Can be used on structural plastics that cannot tolerate high baking temperatures
• Free of lead hazards as packaged in compliance with Consumer Product Safety Commission’s (CPSC) 16 CFR Chapter II: subchapter B, part 1303
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.
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.
Clean tools/equipment immediately after use with Polane Reducer. Follow manufacturer's safety recommendations when using any solvent.
The gloss meter provides a quantifiable way of measuring gloss intensity ensuring consistency of measurement by defining the precise illumination and viewing conditions. The configuration of both illumination source and observation reception angles allows measurement over a small range of the overall reflection angle. The measurement results of a gloss meter are related to the amount of reflected light from a black glass standard with a defined refractive index. The ratio of reflected to incident light for the specimen, compared to the ratio for the gloss standard, is recorded as gloss units (GU).
Measurement angle refers to the angle between the incident and reflected light. Three measurement angles (20°, 60°, and 85°) are specified to cover the majority of industrial coatings applications. The angle is selected based on the anticipated gloss range, as shown in the following table.
Low (20-25 units at 60 degrees) as a smooth coat
Note: "As Packaged = 50-80 Krebs Units. Viscosity varies by color.
The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress. For liquids, it corresponds to the informal notion of "thickness". For example, honey has a higher viscosity than water.
Viscosity is due to friction between neighboring parcels of the fluid that are moving at different velocities. When fluid is forced through a tube, the fluid generally moves faster near the axis and very slowly near the walls, therefore some stress (such as a pressure difference between the two ends of the tube) is needed to overcome the friction between layers and keep the fluid moving. For the same velocity pattern, the stress required is proportional to the fluid's viscosity. A liquid's viscosity depends on the size and shape of its particles and the attractions between the particles.
A fluid that has no resistance to shear stress is known as an ideal fluid or inviscid fluid. Zero viscosity is observed only at very low temperatures, in superfluids. Otherwise all fluids have positive viscosity. If the viscosity is very high, for instance in pitch, the fluid will appear to be a solid in the short term. A liquid whose viscosity is less than that of water is sometimes known as a mobile liquid, while a substance with a viscosity substantially greater than water is called a viscous liquid.
In paint industries, viscosity is commonly measured with a Zahn cup, in which the efflux time is determined and given to customers. The efflux time can also be converted to kinematic viscosities (centistoke, cSt) through the conversion equations. A Ford viscosity cup measures the rate of flow of a liquid. This, under ideal conditions, is proportional to the kinematic viscosity.

Recommended Dry Film Thickness: (DFT)
Note: Mils Wet 3.0 - 4.0
Coating material when dry (after curing) should typically have a thickness of 30–130 µm (0.0012–0.0051 in) when using acrylic resin, epoxy resin, or urethane resin. For silicone resin, the coating thickness recommended by the IPC standards is 50–210 µm (0.0020–0.0083 in).
There are several methods for measurement of conformal coating thickness and they fall into two categories. These categories are wet film and dry film conformal coating measurements
An alternative method to wet film measurement is using a non contact technique using eddy currents. The system works by placing the test head on the surface of the conformal coating, the measurement is almost instantaneous and provides an immediate repeatable result for thickness measurement of conformal coating.
Test coupons are the ideal method for measuring the coating thickness, whether is it spraying or dipping, and can be kept as a physical record of the performance. Apply the coating to the test coupons at the same time as the circuit boards provides a permanent measurement and an accurate guide to the coating thickness.
