PU coating on Tent? Yahoo Answers.
PU coating on Tent? We have just bought a tent from Argos and it says it has a PU coating what exactly does this mean? That it is waterproof/showerproof/fireproof? Any info would be much appreciated! Update Thank you that is good to know! Are you sure that you want to delete this answer? Sorry something has gone wrong. Best Answer nbsp PU Coated means te nylon fabric has been coverd in waterproofing. It isnt however fireproof unless it says it.

Polyurethane Wikipedia the free encyclopedia.
Jump to navigation search. Polyurethane synthesis wherein the urethane groups NH-CO-O link the molecular units. Polyurethane PUR and PU is a polymer composed of a chain of organic units joined by carbamate urethane links. While most polyurethanes are thermosetting polymers that do not melt when heated thermoplastic polyurethanes are also available. Polyurethane polymers are traditionally and most commonly formed by reacting a di or poly isocyanate with a polyol. Both the isocyanates and polyols used to make polyurethanes contain on average two or more functional groups per molecule. Some noteworthy recent efforts have been dedicated to minimizing the use of isocyanates to synthesize polyurethanes because the isocyanates raise severe toxicity issues.

Other types of polyurethane coatings are used in construction where building floors steel trusses and concrete supports are spray-coated to make them more durable and less costly to maintain. This coating for example makes a suspension bridge easier to clean helps to keep its support beams from rusting and improves its appearance even from a great distance. Coatings used in the aerospace industry protect the external parts of aircraft from extreme temperature differencesfrom summer heat on the ground to below-freezing at cruising altitudesand help protect the skin of the plane from rust and pitting. Polyurethane Adhesives and Sealants. Polyurethane adhesives and sealants provide strong bonding and tight seals in a variety of applications.
FAQ Acrylic Polyurethane and Silicone Proofing Techniques.
Technically the silnylon fabric is double-coated. That is a coating of silicone polyer has been applied to both sides. Well fair enough but there is a huge difference in the result between PU and silicone coating. The PU coating sits on the surface of the fabric but the silicone polymer goes right in. As far as I can see with a microscope the silicone polymer completely permeates the fabric fibers and forms a layer right through the fabric. As far as the final fabric properties are concerned you should not think of silnylon as a coated fabric but rather as nylon-fabric-reinforced silicone polymer sheet. This is a bit like fibreglass or glass-reinforced epoxy. This difference translates into mechanical properties too. A key parameter is tear strength.
