Problems solved by technology

However, this type of composition solves only one problem associated with surfaces in the sun and is therefore limited in its ability to reduce the temperature of the surface being coated
Furthermore, infrared reflective pigments are expensive and only available in a limited number of colors, thus limiting the choices available to potential consumers

Embodiment 1

[0088] For all examples, the following formulations of coating compositions were used.

[0089] A control composition comprising a general purpose latex paint formulation was prepared.

[0090] A general purpose latex paint formulation comprising a control composition was prepared together with 12.1660% by weight SCOTCHLITE K46 glass microspheres and 0.4136% by weight Natrosol H 4 Prototype composition of Br.

Embodiment 2

[0092] Control and prototype compositions were prepared essentially according to Example 1. Both the control composition and the prototype composition were tinted in 18 different colors. Two coats of each control and prototype composition were rolled onto 12x12 concrete blocks. The control and prototype compositions were applied to the same piece to reduce substrate-to-substrate variation. The blocks were placed under a 2GE Halogen 100W 120V lamp for 30 minutes in the laboratory. The surface temperature of the coated surface was measured at various time intervals from 2 to 240 minutes using a handheld IR temperature gun. Such as figure 2 As shown, the control composition had an average temperature of 118.7°F with a standard deviation of 10.3°F, and the prototype composition had an average temperature of 102.44°F with a standard deviation of 10.3°F.

Embodiment 3

[0096] Control and prototype compositions were prepared essentially according to Example 1. Both the control composition and the prototype composition were tinted in 18 different colors. Two coats of each control and prototype composition were rolled onto 12x12 concrete blocks. The control and prototype compositions were applied to the same piece to reduce substrate-to-substrate variation. The blocks were placed under a 2GE Halogen 100W 120V lamp for 240 minutes in the laboratory. The surface temperature of the coated surface was measured at various time intervals from 2 to 240 minutes using a handheld IR temperature gun. The control composition had an average temperature of 162.5°F with a standard deviation of 17.9°F and the prototype composition had an average temperature of 134.7°F with a standard deviation of 13.7°F. The results are shown in Figure 5 middle.

Abstract

The present technology provides a coating composition suitable for maintaining a cooler surface temperature in the presence of a UV source, e.g., the sun, as compared with a conventional coating composition. The present coating composition can reflect the sun's rays to provide a cooler surface when compared to other compositions of similar colors. The coating can be used to coat a variety of substrates and can be used, for example, as a coating for walking surfaces. When applied to a walking surface, the coating composition may provide a cooler surface that is barefoot-friendly, even in the presence of the sun or other strong UV source.

Description

technical field [0001] This application claims priority to and benefit of U.S. Provisional Application No. 62 / 822,246, filed March 22, 2019, the entire disclosure of which is incorporated herein by reference. [0002] The present technology relates to coating compositions for reducing the surface temperature of a substrate to which they are applied. Background technique [0003] In general, surfaces exposed to sources of UV radiation can become hotter to the touch due at least in part to the absorption of light by the surface. Dark surfaces such as black absorb almost all wavelengths of light. When light radiation is absorbed, it is converted into another form of energy, usually heat, which is then emitted through the surface. Therefore, the darker an object is, the better it dissipates heat, and thus the hotter it is to the touch. [0004] Anyone who has walked on asphalt on a hot sunny day knows firsthand how hot asphalt is. Additionally, a swimmer can face the same ...
