  • Heat dissipating coating and method for decreasing the inner temperature of buildings and similar constructions
    Patent number: 6902611
    Abstract: A heat-dissipating aqueous coating composition and a method for making more comfortable the inner temperature of buildings, housings and the like, by applying a thin layer of said aqueous composition on the exterior surfaces of roofs and walls, which composition dissipates heat from said roofs and walls through evaporation of water which is absorbed from ambient air by a hygroscopic material contained in said composition. The absorption-evaporation cycle is repeated through the daily natural relative changes of relative humidity of ambient air following the heating and cooling cycles of said roofs and walls exposed to solar radiation. The aqueous composition contributes to savings in energy consumption of air conditioning equipment and may be applied with excellent adherence and durability over exterior surfaces of concrete, metallic sheet and other materials.

  • Particle binding compositions and methods of making and using such compositions
    Patent number: 6881008
    Abstract: Particle binding compositions useful for stabilizing soil and other particles comprise water, an endosperm, an iron compound, a strong base, and a pH adjustor. The endosperm comprises the carbohydrate and protein portions of grains, seeds, or tubers. The strong base is reacted with the endosperm in the presence of water added in order to ionize the carbohydrate and protein of the endosperm and render them more soluble or dispersible in water. The iron compound promotes an electrochemical reaction that assists in the formation of a silicate crystal matrix when applied to soil. The pH adjustor lowers the pH of the composition, which improves handling ability and renders the composition more compatible with soil. Optional components such as fibrous materials and/or seeds can be added to promote vegetation or revegetation of denuded soils.
