Abstract:

A method for increasing a detection distance of a surface of an object illuminated by near-IR electromagnetic radiation, including: (a) directing near-IR electromagnetic radiation from a near-IR electromagnetic radiation source towards an object at least partially coated with a near-IR reflective coating that increases a near-IR electromagnetic radiation detection distance by at least 15% as measured at a wavelength in a near-IR range as compared to the same object coated with a color matched coating which absorbs more of the same near-IR radiation, where the color matched coating has a ΔE color matched value of 1.5 or less when compared to the near-IR reflective coating; and (b) detecting reflected near-IR electromagnetic radiation reflected from the near-IR reflective coating. A system for detecting proximity of vehicles is also disclosed.

International Classification:

H04B 1/03
C09D 133/10

Abstract:

The present invention is directed to coated articles demonstrating a transmission of electromagnetic radiation having a frequency of 22 to 81 GHz in the range of 70% to 100%. The articles comprise substrates coated with curable film-forming compositions comprising a first film-forming polymer prepared from at least one hydrophobic monomer, a second film-forming polymer prepared from at least one hydrophobic monomer, and a curing agent. Upon application of the curable film-forming composition to the substrate to form a coating layer, the first film-forming polymer is distributed throughout the coating layer, and the concentration of the second film-forming polymer is greater at the surface of the coating layer than the concentration of the second film-forming polymer within the bulk of the coating layer. The present invention is also drawn to methods of mitigating contaminant build-up on a substrate using the curable film-forming compositions described above.

International Classification:

C09D 5/33
G02B 5/08

Abstract:

A coating composition for application over a retroreflective substrate, a retroreflective article comprising a coating formed from the coating composition, and a method of production thereof are provided. The coating composition comprises a pigment suitable to absorb and/or scatter electromagnetic radiation in a wavelength range of 800 nm to 2000 nm. The coating comprises a ratio of reduction in electromagnetic radiation retroreflectance at a wavelength of 905 nm and/or 1550 nm to reduction in electromagnetic radiation retroreflectance averaged over a wavelength range of 400 nm to 700 nm of at least 2:1.

Abstract:

A cleaning fluid composition, a method of manufacture of the fluid composition, and a method of use thereof are provided. The fluid composition comprises 10% to 50% by weight of an alcohol based on the total weight of the fluid composition, 2% to 40% by weight of a co-solvent based on the total weight of the fluid composition, and at least 20% by weight of water based on the total weight of the fluid composition. The co-solvent is miscible with water, the fluid composition is substantially free of ethylene glycol and methanol, and the fluid composition has a viscosity less than or equal to 45 cP at −25 degrees Celsius and a freezing point less than −25 degrees Celsius.
