Buff Titanium 500 g
Most titanium dioxides are pure white and expensive, but Buff Titanium demonstrates that whiteness is not a pre-requisite for effectiveness in color formulations. Here is a comparison of buff titanium to titanium white.
|Buff Titanium||Titanium White|
|• In colored products, offers comparable performance characteristics to titanium white: opacity, consistency, color quality||• Pigment standard for use in white products|
|• Natural ”neutral“ color allows reduction of expensive additional tinting pigments||• In colored products, resulting whiteness must be ”overcome“ by tinting with expensive additional color pigments|
|• Reduction of expensive additional further lowers cost of finished product||• Additional pigments add cost of finished product|

Buff titanium pigment is manufactured from an intermediate raw material, synthetic rutile, which is in turn made from ilmenite sands. Buff titanium is made from synthetic rutile in a process that incorporates fluid energy milling. During the manufacture of synthetic rutile, high temperature calcination and strong acid leaching render buff titanium dioxide inactive and inert. The process produces a high quality pigment, leaving only a very small percentage of iron oxide.
The small percentage of iron oxide remaining gives buff titanium its characteristic natural of "buff" color. In the buff titanium process, particles of synthetic rutile mechanically abrade each other to form the end product. It is ground to a specified fineness with particles slightly larger and more irregularly-shaped than typical titanium dioxide white pigment.How is Buff Titanium Used?
In many products that require opacity and color but that do not have to be pure white, buff titanium can economically replace all or part of the titanium white or other expensive pigments that may be used. Depending on the finished color desired, buff titanium can replace from 15 to 100% of the titanium white used, at a cost savings. In addition to replacing titanium white, buff titanium may also allow reduction of amounts used of phthalo blues and greens, hansa yellows, organic oranges, synthetic iron oxides and carbon black (in whole or in part, again depending on desired color). Buff titanium is chemically inert and considered to be non-toxic, allowing you to save on your total pigment cost and achieve equal or better opacity, consistency and color quality.Applications for Buff Titanium
Some examples of coatings applications in which buff titanium is used widely and successfully are many types of architectural paints, traffic marking paints, automotive and maintenance primers, and coatings for appliances and office furniture. Coating systems which may incorporate buff titanium include alkyds, acrylics, urethanes, and powder coatings. Plastics uses include primarily green, gray, blue and beige plastic PVC pipe and conduit, vinyl siding, floor tiles, color concentrates and plastic film.
Buff Titanium may also be used in inks, adhesives, paper, foundry products and building materials.Permanence and Compatibility
Buff titanium is a synthetic white pigment that is rated by the American Society of Testing and Materials (ASTM International) as lightfastness category I, which is the highest lightfastness. It is compatible with all pigments, and is resistive to acids and alkalis.Oil Absorption and Grinding
Buff titanium absorbs a low to moderate amount of oil (15 to 25 grams per 100 grams of pigment), which may slow the drying of oil paint and hence is a moderate drying oil color. It is highly refractive pigment and is difficult to grind in oil, although it easily disperses in water.Toxicity
Buff titanium is not considered toxic, but care should be used in handling the pigment.
