Despite showing clothing in the videos, it doesn't recommend that people use the solution on clothing, though fabrics are fine. Additionally, while an iPhone is shown in a few user demonstration videos, the company doesn't suggest applying it to electronics right now. Ashley Lehrmann, senior director of brand management for Rust-Oleum, says that electronics such as the iPhone and other smartphones require a bit more user precision.
A company named Liquipel offers a similar service. A coating applied to phones by the company, which isn't visible to the naked eye, repels water.
It requires you send the phone to the company for the treatment, however. The time we can finally stop washing our clothes is nigh. Search Events Jobs Consulting. Topics Science Magazine June Issue. Other potential applications include a variety of objects and places, such as shoes, electrical equipment, clothing, hospitals, bathroom products, and much more.
Lancaster Online has an informative interview with several of the people behind NeverWet, including co-inventor Vinod Sikka. He admits to the Pennsylvania newspaper, "It's challenging to break into the coatings market.
People have been using the same stuff from the same suppliers for a long time. It is very novel, and when you start thinking about it, you can think about how transformative the technology can be," Jones said. The coating composition may advantageously be prepared using VOC exempt compounds that are compatible with a variety of surface materials including many electronic components.
A variety of hydrophobic and oleophobic surface coating compositions have been described that employ high amounts of volatile organic compounds VOCs including those that participate in atmospheric photochemical reactions.
The compositions set forth in this disclosure may optionally include one or more types of first particles in addition to third particles.
UV curable versions of water-based polyurethanes e. Polyurethanes are polymers consisting of a chain of organic units joined by urethane carbamate linkages. Polyurethane polymers are typically formed through polymerization of at least one type of monomer containing at least two isocyanate functional groups with at least one other monomer containing at least two hydroxyl alcohol groups. A catalyst may be employed to speed the polymerization reaction. Other components may be present in the polyurethane coating compositions to impart desirable properties including, but not limited to, surfactants and other additives that bring about the carbamate forming reaction s yielding a coating of the desired properties in a desired cure time.
In some embodiments, the polyurethane employed in the durable coatings may be formed from a polyisocyanate and a mixture of -OH hydroxyl and NH amine terminated monomers. In such systems the polyisocyanate can be a trimer or homopolymer of hexamethylene diisocyanate HDI.
HDI Trimer Polyalcohol Polyurethane Some solvents compatible with such systems include water, n-butyl acetate, toluene, xylene, ethyl benzene, cyclohexanone, isopropyl acetate, N-methyl pyrrolidone, and methyl isobutyl ketone and mixtures thereof; although not all of these solvents are VOC-exempt.
The structures of some examples of polyacrylic urethanes, polyester urethanes, and polycarbonate urethanes are provided below TO 40 g amounts of each mixture was added 4. All percentages are calculated and based on g of mixture.
The compositions were each mixed using steel balls or a low impact mixer. Each mixture was sprayed using an air gun on 4x 4-in square steel plates at five different thicknesses.
All of the plates were air-dried for 30 niin prior to drying in an oven at [deg. Each plate was subjected to thickness measurement, surface roughness measurement Ra and Rz values , and wear resistance using a Taber abrader Taber abrasion. All Taber abrasion measurements were obtained using g load and CS10 wheels. Data are summarized in Table 5 and plotted in Figs. When any liquid hits this barrier, it forms beads that roll of the surface without clinging on. This is often referred to as the Lotus effect.
Nokia demonstrated such technology in October at its Nokia World conference in London. Chocolate sauce slides off a pair of white shoes that have been sprayed with NeverWet.
