The amount of epoxy needed depends on the size of your project area and the application type (coating, casting, flooring, etc.). Typically, to cover a standard floor with a thickness of 1/16 inch, you need about 0.13 gallons per square foot. Therefore, for a 100 square foot area, you would require approximately 13 gallons. However, factors like surface porosity and the desired thickness of the epoxy layer can adjust this estimate. It's crucial to accurately measure your space and consult the epoxy manufacturer's guidelines for specific coverage rates, considering extra for waste or mishaps. When in doubt, it's better to have a bit more epoxy than you calculated to ensure complete coverage.
Whether polyurea is better than epoxy depends on the specific requirements of the application. Polyurea coatings are known for their rapid curing time, flexibility, and strong resistance to chemicals and abrasions, making them ideal for environments requiring quick returns to service and high durability. On the other hand, epoxy coatings offer excellent adhesion, corrosion resistance, and a durable surface at a typically lower cost. Epoxy might be preferred for indoor applications, such as floors and countertops, where time is less critical, and there’s a need for a high level of protection against impacts and stains. Polyurea excels in challenging outdoor environments and where elasticity is beneficial, such as in waterproofing and in conditions with extreme temperature fluctuations. Ultimately, the choice between polyurea and epoxy should be based on the specific performance characteristics required for the project, including environmental exposure, traffic levels, and budget considerations.
Titanium dioxide (TiO2) originates primarily from the minerals ilmenite, rutile, and anatase, which are found in the earth's crust. Ilmenite is the most abundant source, though rutile is richer in titanium. This compound is mined in various parts of the world, with major contributions from Australia, South Africa, and Canada. Once extracted, the minerals undergo a series of processing steps. For rutile, this involves chlorine-based conversion to titanium tetrachloride before being oxidized to produce the pure titanium dioxide. Ilmenite, on the other hand, can be upgraded to synthetic rutile or directly processed via the sulfate process or chloride process, depending on the intended use and required purity of the final product. Titanium dioxide is used extensively as a pigment due to its brightness, high refractive index, and resistance to discoloration. It's found in paints, plastics, papers, foods, and pharmaceuticals, among other applications.
Titanium dioxide is derived from titanium, which is actually the ninth most abundant element in the Earth’s crust. The titanium is extracted from ores, such as ilmenite and rutile. These ores are primarily sourced from Australia, South Africa and Canada. Titanium dioxide is then processed in various ways for use in a diverse range of applications, including paint, sunscreen, toothpaste, and food coloring.
