A superhydrophobic coating is a thin surface layer that repels water. It is made from superhydrophobic (also known as ultrahydrophobic) materials, and typically cause an almost imperceptibly thin layer of air to form on top of a surface. Droplets hitting this kind of coating can fully rebound. [ 1][ 2] Generally speaking, superhydrophobic ...
Waterproof paper uses special coatings ( plastic-coated paper) and fibers to enhance durability, dimensional stability, tear resistance and resistance to changing shape or texture when exposed to water. The paper has applications for wet or damp environments, including outdoor, marine, field uses as well as printing applications for similar ...
PUR is better than hotmelt or cold glue for most applications. Because of the lack of moisture in the glue, paper with contrary grain direction can be glued without problems. Even printed and supercalendered paper can be bound without problems. It is the most economical glue, with a theoretical application thickness of 0.01 mm.
Waterproofing is the process of making an object, person or structure waterproof or water-resistant so that it remains relatively unaffected by water or resisting the ingress of water under specified conditions. Such items may be used in wet environments or underwater to specified depths. Water-resistant and waterproof often refer to resistance ...
Durable water repellent. Fluorine-containing durable water repellent makes a fabric water-resistant. Durable water repellent, or DWR, is a coating added to fabrics at the factory to make them water-resistant ( hydrophobic ). Most factory-applied treatments are fluoropolymer based; these applications are quite thin and not always effective.
Bitumen (asphalt or coal-tar pitch) is a material made up of organic liquids that are highly sticky, viscous, and waterproof. [ 1] Systems incorporating bituminous-based substrates are sometimes used to construct roofs, in the form of "roofing felt " or "roll roofing" products.
Infobox references. PBAT (short for polybutylene adipate terephthalate) is a biodegradable random copolymer, specifically a copolyester of adipic acid, 1,4-butanediol and terephthalic acid. PBAT is produced by many different manufacturers and may be known by the brand names ecoflex, Wango, Ecoworld, Eastar Bio, and Origo-Bi.
The whole phone is covered by an invisible layer of splash-proof nano coating, which makes the phone water-resistant to occasional liquid splashes. The Droid Razr features four touch-capacitive buttons with the respective functions of menu, home, back and search. It uses a dual microphone system for noise reduction.
