Florida Finishing POLANE Dead Flat Black Polyurethane
POLANE Dead Flat Black Polyurethane is a two component
polyurethane formulated to be used
wherever exposure of product to a wide
variety of elements is anticipated,
wherever continued endurance over an
extended period of time is expected. Its appearance, exceptional adhesion and
low curing time and temperature suit is not
only to metal surfaces, but to structural
materials, such as polyester, fiberglass,
structural foam, ABS plastic, SMC, nylon
and many other plastic substrates. (For
complete system on the aforementioned
substrate, contact Sales.)

Two package urethane coatings contain isocyanates. These materials may sensitize certain individuals. In spray application where over spray is not controlled, air supplied respirators are recommended to prevent exposure. Where air supplied respirators are not available, a chemical cartridge particulate combination respirator recommended by the manufacturer for protection against isocyanate spray paint, should be used.

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.
Dead Flat / 1-6 at 60°
High Gloss: 85+ Units
Note: Viscosity measurements include Base and Catalyst and Reducer.
Zahn and Ford viscosity cups measure the rate of flow of a liquid.
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 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 or Ford 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.
Theoretical Coverage: (no application loss)
Also known as the "Spreading Rate". Theoretical Coverage uses the total contents of an AD-MIXED coating. (Part A, plus Part B, plus Part C) Including all catalyst and reducer necessary to meet the Manufacturer Mixing Recommendations as specified on the Product Data Sheet.

Recommended Dry Film Thickness: (DFT)
Note 1: Spatter or texture coat may be applied immediately after flash off of smooth coat.
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.

Note 1: Heat shortens pot life.
Note 2: Begin POT LIFE time from Mixing.
Note 3: Protect from moisture, water affects pot life and product properties.
All two-part coatings have a "pot-life" or "working time" during which the coating can be used. Usually the pot-life is a matter of a few hours but is also highly temperature dependent. Both water-borne and solvent based coatings have a Pot-Life.
