In food, titanium dioxide has a few different uses. Most notably, its food-grade form is used as a colorant to enhance and brighten the color of white foods such as dairy products, candy, frosting, and the powder on donuts. For foods that are sensitive to UV light, titanium dioxide is used for food safety purposes to prevent spoilage and increase the shelf life of food.
Resumen–En este artículo se discute el descubrimiento del litopón fosforescente en dibujos a la acuarela por el artista americano John La Farge, fechados de 1890 a 1905, y la historia del litopón en la industria de los pigmentos a finales del Siglo XIX y principios del Siglo XX. A pesar de tener muchas cualidades deseables para su uso en pintura para acuarela o pinturas al óleo blancas, el desarrollo del litopón como pigmento para artistas fue obstaculizado por su tendencia a oscurecerse con la luz solar. Su disponibilidad para los artistas y su adopción por ellos sigue siendo poco clara, ya que por lo general los catálogos comerciales de los coloristas no eran explícitos al describir si los pigmentos blancos contenían litopón. Además, el litopón se puede confundir con blanco de plomo durante el examen visual, y su fosforescencia de corta duración puede ser fácilmente pasada por alto por el observador desinformado. A la fecha, el litopón fosforescente ha sido documentado solamente en otra obra mas: una acuarela por Van Gogh. Además de la historia de la fabricación del litopón, el artículo detalla el mecanismo para su fosforescencia, y su identificación con la ayuda de espectroscopía de Raman, y de espectrofluorimetría.
When choosing lithopone, you must choose a good brand and pay attention to its production date. Some people just don’t pay attention to this aspect and often pursue cheap prices. As a result, they buy products that are close to their expiration date and have not been stored for long. It is no longer usable. This is very important.
Titanium dioxide (E171) is an additive that is used in food as a colour. The function of food colours is to make food more visually appealing, to give colour to food that would otherwise be colourless, or to restore the original appearance of food. Titanium dioxide is used to provide whiteness and opacity to foods.
Although barium sulfate is almost completely inert, zinc sulfide degrades upon exposure to UV light, leading to darkening of the pigment. The severity of this UV reaction is dependent on a combination of two factors; how much zinc sulfide makes up the pigments formulation, and its total accumulated UV exposure. Depending on these factors Lithopone B301, Lithopone B311 powder itself may vary in shade over time, ranging from pure white all the way to grey or even black. To suppress this effect, a dopant might be used, like small amount of cobalt salts, which would be added to the formulation. This process creates cobalt-doped zinc sulfide. The cobalt salts help to stabilize zinc sulfide so it will not have as severe a reaction to UV exposure.

The versatility of 2-inch wide foam weather stripping makes it suitable for a wide range of applications. It is commonly used around exterior doors and windows, but its utility extends beyond these areas. Here are some additional applications
Installation and Maintenance
1. Remove the Old Seal If the door seal is visibly damaged, you will need to remove it. Carefully pry it away from the doorframe using a putty knife. If the old seal is glued on, applying some solvent around the edges can help loosen it.
Foam tape is composed of a layer of foam material, typically polyurethane or polyethylene, sandwiched between layers of adhesive. With a thickness of just 2mm, this tape strikes a balance between being thick enough to provide cushioning and thin enough to remain discreet. The foam allows for some degree of compression, enabling the tape to adjust to irregular surfaces and making it ideal for applications where a firm yet flexible bond is necessary.
Car sealing strips are a crucial component of a vehicle that often goes unnoticed. These rubber strips are located in various parts of the car, such as around the doors, windows, and trunk, and serve several important functions.
In marine settings, rubber weather seals are equally vital. Boats and yachts are constantly exposed to salty air and water, which can be detrimental to the structural integrity of the crafts. Weather seals prevent water intrusion, helping to keep cabins dry and safe. The harsh marine environment demands seals that can withstand UV radiation, saltwater, and extreme temperatures.
