Materials used as vapor retarders: Elastomeric coatings can provide a vapor barrier and water proofing with permeability ratings of .016 perm rating with 10 mils/min. of coating and can be applied on interior or exterior surfaces. Aluminum foil, 0.05 US perm (2.9 SI perm). Paper-backed aluminum.
Between 2009 and 2021, over 440 million gallons of long-term fire retardant were dumped across federal, state and private land, most of it in the western U.S., according to federal estimates.
A fire retardant is a substance that is used to slow down or stop the spread of fire or reduce its intensity. This is commonly accomplished by chemical reactions that reduce the flammability of fuels or delay their combustion .
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.
Specifically, organic polymers can work as a flame retardant due to the presence of one or all three types of these elements. These atoms can be in the original polymers, or they can be incorporated by chemical modification. [15] Flame retardant materials and coatings are being developed that are phosphorus and bio-based. [21]
TPhP, in particular, has been found to enter the environment through industrial use, as in the manufacturing process, and through indoor use, for example through paints and electronic equipment. [12] As with many other phosphorus-containing flame retardants, TPhP has been found widely in sediment, soil, indoor dust, and air. [5] [11] [14] [15] [16]
Titanium nitride (TiN; sometimes known as tinite) is an extremely hard ceramic material, often used as a physical vapor deposition (PVD) coating on titanium alloys, steel, carbide, and aluminium components to improve the substrate's surface properties.
Coatings that alter or have magnetic, electrical or electronic properties. [44] [45] [46] Flame retardant coatings. [47] [48] [49] Flame-retardant materials and coatings are being developed that are phosphorus and bio-based. [50] These include coatings with intumescent functionality. [51] Non-stick PTFE coated cooking pots/pans. [52]
