2. Paint protection film - Wikipedia

   en.wikipedia.org/wiki/Paint_protection_film

   Paint protection film (PPF, also called clear bra, clear film or clear paint film) is a thermoplastic urethane often self-healing film applied to painted surfaces of a new or used car in order to protect the paint from stone chips, bug splatters, and minor abrasions. This film is also used on airplanes, RVs, cell phones, electronics, screens ...

3. Automotive paint - Wikipedia

   The base coat is applied after the primer coat. This coat contains the visual properties of color and effects, and is usually the one referred to as the paint. Base coat used in automotive applications is commonly divided into three categories: solid, metallic, and pearlescent pigments. Solid paints have no sparkle effects except the color ...

4. Conformal coating - Wikipedia

   en.wikipedia.org/wiki/Conformal_coating

   Coating material (after curing) should 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).

5. Optical coating - Wikipedia

   FROCs enjoy remarkable structural coloring properties, as they can produce colors across a wide color gamut with both high brightness and high purity. [11] Moreover, the dependence of color on the angle of incident light can be controlled through the dielectric cavity material, making FROCs adaptable for applications requiring either angle ...

6. Polyurethane dispersion - Wikipedia

   en.wikipedia.org/wiki/Polyurethane_dispersion

   Polyurethane dispersion, or PUD, is understood to be a polyurethane polymer resin dispersed in water, rather than a solvent, although some cosolvent may be used.Its manufacture involves the synthesis of polyurethanes having carboxylic acid functionality or nonionic hydrophiles like PEG (polyethylene glycol) incorporated into, or pendant from, the polymer backbone.

7. Carbamate - Wikipedia

   en.wikipedia.org/wiki/Carbamate

   The etymology of the words "urethane" and "carbamate" are highly similar but not the same. The word "urethane" was first coined in 1833 by French chemist Jean-Baptiste Dumas. [38] [39] Dumas states "Urethane. The new ether, brought into contact with liquid and concentrated ammonia, exerts on this substance a reaction so strong that the mixture ...
