2. Conformal coating - Wikipedia

   en.wikipedia.org/wiki/Conformal_coating

   Conformal coating is a protective, breathable coating of thin polymeric film applied to printed circuit boards (PCBs). Conformal coatings are typically applied with 25–250 μm [ 1 ] thickness on electronic circuitry to protect against moisture and other substances.

3. Anti-fog - Wikipedia

   en.wikipedia.org/wiki/Anti-fog

   Anti-fog agents are available as spray solutions, creams and gels, and wet wipes, while more resistant coatings are often applied during complex manufacturing processes. Anti-fog additives can also be added to plastics where they exude from the inside to the surface.

4. Fiberglass spray lay-up process - Wikipedia

   en.wikipedia.org/wiki/Fiberglass_spray_lay-up...

   The gelcoat (a smooth, hard polyester resin coating) is applied to the mould surface and is given time to cure before re-applying. Usually two coats of gelcoat are used. The barrier coat is applied to avoid fibre print and a rough surface through the gel coat. The barrier coat is cured in an oven and left to cool to room temperature.

5. Thermal spraying - Wikipedia

   en.wikipedia.org/wiki/Thermal_spraying

   Unlike other types of thermal spray, spray and fuse creates a metallurgical bond between the coating and the surface. This means that instead of relying on friction for coating adhesion, it melds the surface and coating material into one material. Spray and fuse comes down to the difference between adhesion and cohesion.

6. Detonation spraying - Wikipedia

   en.wikipedia.org/wiki/Detonation_spraying

   After a surface has been abrasion blasted and/or machined a thin layer of molybdenum, nickel-chromium alloys or nickel aluminide can be spayed before the final detonation spray coating to improve the bond strength. This is known as a bond coating. Bond coatings are often used when spray coating materials of ceramic composites are being applied.

   en.wikipedia.org/wiki/Silicone

   Silicone caulk can be used as a basic sealant against water and air penetration. In organosilicon and polymer chemistry, a silicone or polysiloxane is a polymer composed of repeating units of siloxane (−O−R 2 Si−O−SiR 2 −, where R = organic group). They are typically colorless oils or rubber-like substances. Silicones are used in ...
