What are the other names for IRON OXIDE RED H130?
IRON OXIDE RED H130 is also referred to as Ferric Oxide, Fe2O3, Red Iron Oxide and Pigment Red 101. These names describe the same substance, so a specification or enquiry written against any of them can be matched to this product.
What grade of IRON OXIDE RED H130 is supplied?
IRON OXIDE RED H130 is supplied as Technical grade. State the grade your process requires when requesting a quotation — where an alternative grade can be sourced, it is confirmed at quotation stage rather than assumed.
What concentration is IRON OXIDE RED H130 supplied at?
IRON OXIDE RED H130 is supplied at a concentration of 95-105%. Concentration and assay are separate figures: the concentration describes the strength of the material as supplied, and the certificate of analysis issued for your consignment carries the measured values for that batch.
What is the purity of IRON OXIDE RED H130?
The purity/assay figure recorded for IRON OXIDE RED H130 is ≥95%. Figures are typical values for the grade supplied; the certificate of analysis for your specific batch is the authoritative record and can be provided on request.
What does IRON OXIDE RED H130 look like?
IRON OXIDE RED H130 is described as finely milled red powder. Appearance is a useful first check on receipt of goods, though it does not replace the certificate of analysis for confirming that the material meets specification.
What is IRON OXIDE RED H130 used for?
Common applications include building materials — imparts vibrant color to concrete, bricks, and tiles, paints and coatings — enhances anti-rust and UV resistance in wall paints and enamels, plastics — provides consistent pigmentation and color fastness, rubber — used for heat-stable pigmentation, ceramics and glazes — adds color consistency and durability and paper and asphalt — enhances aesthetic and functional properties. The suitability of the product for a particular process depends on the grade and specification required, which is worth confirming against your own process conditions.
Which industries use IRON OXIDE RED H130?
