SACHTLEBEN® R405 pigment is an alumina surface-treated hydrophobic titanium dioxide pigment offering rapid and excellent dispersibility in a large range of polymers in dry processing as well as in liquid plasticizers. SACHTLEBEN® R405 pigment fine crystal and particle sizes position it in the group of blue undertone plastics grades.
SACHTLEBEN® R405 pigment is particularly recommended for use in systems in which fineness of pigment dispersion in the polymer is the top priority: polyolefins, styrenics, engineering polymers, etc. SACHTLEBEN® R405 pigment permits production of highly pigmented concentrates, such as polyolefin masterbatches, for instance. It can also be used in rubber and linoleum. SACHTLEBEN® R405 pigment enables the manufacture of highly pigmented concentrates, e.g., 70% plasticizer preparations of all widely used liquid plasticizers.

As for all fine powders, the handling of titanium dioxide pigments can give rise to airborne dust. Good industrial hygiene practice should be observed so as to avoid the generation and subsequent inhalation of dust. For more information, refer to our material safety data sheet.
The pigment should not be stored in outside areas exposed to the weather. All direct contact with moisture should be avoided. By storing the pigment correctly, its properties should not deteriorate with time. However, to ensure optimum performance, it is recommended that the product is used on a first-in, first-out basis from receipt of shipment.
Venator’s titanium dioxide pigments are available in 25kg bags and a range of flexible intermediate bulk containers.
