Dazzle consists in painting obtrusive patterns on vertical surfaces. Unlike some other forms of camouflage, dazzle works not by offering concealment but by making it difficult to estimate a target's range, speed and heading. Each ship's dazzle pattern was unique to make it more difficult for the enemy to recognize different classes of ships.
Dry lubricants or solid lubricants are materials that, despite being in the solid phase, are able to reduce friction between two surfaces sliding against each other without the need for a liquid oil medium. [1] The two main dry lubricants are graphite and molybdenum disulfide. They offer lubrication at temperatures higher than liquid and oil ...
In industry, super-hydrophobic coatings are used in ultra-dry surface applications. The coating can be sprayed onto objects to make them waterproof. The spray is anti-corrosive and anti-icing; has cleaning capabilities; and can be used to protect circuits and grids. Superhydrophobic coatings have important applications in maritime industry ...
In the paint and coating industries, paint adhesion testing is often used to determine if the paint or coating will adhere properly to the substrates to which they are applied. Several tests measure the resistance of paints and coatings from substrates: cross-cut test, scrape adhesion, pull-off test , and others.
A water-based primer, used primarily on wood. A primer (/ ˈ p r aɪ m ər /) or undercoat is a preparatory coating put on materials before painting.Priming ensures better adhesion of paint to the surface, increases paint durability, and provides additional protection for the material being painted.
The medium, base, or vehicle is the mixture to which the dry pigment is added. Different media can increase or decrease the rate at which oil paints dry. Often, because a paint is too opaque, painters will add a medium like linseed oil or alkyd to the paint to make them more transparent and pliable for the purposes of glazing.
An alkyd is a polyester resin modified by the addition of fatty acids and other components. [1] Alkyds are derived from polyols and organic acids including dicarboxylic acids or carboxylic acid anhydride and triglyceride oils.
To improve the adhesive and hygroscopic qualities of the paint, as well as the flexibility of the rather brittle paint layer after drying, propylene glycol is often added. [1] Gouache differs from watercolor in that the particles are typically larger, the ratio of pigment to binder is much higher, and an additional white filler such as chalk ...
