WEATHER-RESISTANT, FUNGAL-RESISTANT, AND STAIN-RESISTANT COATINGS AND METHODS OF APPLYING ON WOOD, MASONRY, OR OTHER POROUS MATERIALS

A process for manufacturing the composition coating may include selecting a wood or masonry material substrate and utilizing a sol-gel comprising a silane or silane derivative and metal oxide precursor to coat the substrate. The process may utilize an all solution process or controlled environment for manufacturing a composition coating that prevent wetting and/or staining of a substrate. The composition coatings for treating wood or masonry materials improves weather-resistance, microbial resistance, stain-resistance and fungal-resistance of the materials. The reduced permeability of the resulting masonry materials can also delay or inhibit degradation caused by permeation of ions such as chlorides and sulfates. In addition, a stain comprising the composite solution and pigments may impart additional property to wood or masonry materials whilst retaining or improving the original appearance, particularly for the visibility and contrast of the wood grain as seen after the application of the coating.

Ceramic lamellar composites

Disclosed herein is a method of: placing between a cooling element and an opposing surface a slurry of: a dielectric powder containing barium titanate, a dispersant, a binder, and water; maintaining the cooling element at a temperature below the opposing surface to cause the formation of ice platelets perpendicular to the surface of the cooling element and having the powder between the platelets; subliming the ice platelets to create voids; sintering the powder to form the dielectric material; and filling the voids with the polymeric material. The process can produce a composite having: a sintered dielectric material of barium titanate and platelets of a polymeric material embedded in the dielectric material. Each of the platelets is perpendicular to a surface of the composite.

MATERIAL RESTORATION COMPOSITION AND METHOD
20230295454 · 2023-09-21 ·

A method of restoring a material surface utilizes a first composition (referred to herein as Composition A) and a second composition (referred to herein as Composition B). Methodologies guide application of Composition A and optionally Composition B to enact various restoration advantages to existing or new material surfaces. Composition A may be first applied to a material surface to remove surface contaminants and lift stains. During the described methodology, a user must wait a predetermined amount of time for Composition A to permeate the material surface. Optionally, Composition B may be subsequently applied to bond voids and damages areas of the material surface, or to add a new surface altogether above the original surface. A user may wait a predetermined amount of time for Composition B to cure.
