However, this has the disadvantage of adding considerable weight (coatings, especially PU coatings, are surprisingly heavy) and further reducing tear strength. Polyether urethane is the other member of the polyurethane family that is used in outdoor applications. (silicone coated polyester, which is less common due to polyesterslowertear strength but is sometimes used in tarps). To propagate the tear, youll have to rip through several yarns at once, rather than one yarn at a time. This doesnt factor in much to most companies decisions to coat their fabrics with PU, as its assumed that something else on the tent will break or youll upgrade before hydrolysis becomes a problem. The height of the water (in millimeters) in the tube just as the water begins to penetrate the fabric is called the hydrostatic head rating. Seam sealer (be sure to get the right type for your tent. For tents that will be exposed to large amounts of moisture, PU coatings are often used because they can achieve hydrostatic head ratings in excess of 10,000mm (thats a lot). In this article, well be taking a journey of discovery through the most common waterproof coatings used in tents: polyester urethane (PU), polyether urethane (PE), and silicone, and combinations thereof. The weight and composition of the fabric as well as the intended application are both important factors in coating choice. Finish Floor With Applicator. All fabrics are damaged by UV radiation, which is present in sunlight. Polyurethane gives hardwood its protection. These fabrics are usually laminates (multiple layers of material sandwiched together and adhered with heat or adhesive). Dont do it! This isnt to say that non-PU-coated tents should be stored wet. But those forms of polyurethane that are mainly built for outdoor use (mostly made of oil) have a close relation, instead of differences, with varnish. Over time, the PU coating reacts with moisture in the air (this process is accelerated by heat) and splits the polyester urethane molecule. This is because the oil generates heat as it dries. If youve been there, its time to shore up the waterproofness of your shelter. Get it May 1 - 15. Instead, WPBs utilize a microporous membrane that blocks water droplets but theoretically allows water vapor to pass through. However, if theres enough moisture in the environment, water will eventually saturate the PU coating and go into and through the fabric, causing the coated fabric to leak. It has a distinctive microscopic formulation containing chains of resin molecules. Although PU is the standard and works pretty well under a variety of conditions, there are some drawbacks that make us think that PU is over-utilized in tents.
