Heat Resistance Iron Oxide Black is an inorganic black pigment based on Fe₃O₄, developed for industrial applications requiring significantly higher thermal stability than conventional iron oxide black pigments.
Fineland Chem’s ColorCor®1826 is a Heat Resistance Iron Oxide Black grade classified as Pigment Black 26 (C.I. 77499). It has an Fe₂O₃ content of ≥90%, a specified particle size of 0.2 μm, and heat resistance of up to 600°C.
The combination of fine particle size, high heat resistance, lightfastness, weather resistance, migration resistance, and chemical resistance makes this grade suitable for applications where standard black pigments may not provide sufficient thermal stability.

Heat Resistance Iron Oxide Black ColorCor®1826 ⬇️TDS
Recommended for Building materials, concrete, bricks, paints & coatings, fertilizers, plasticsandrubber polymers, fiber cement, paper, mortar, wood plastic composites, paving tiles, industrial coatings, roof tiles, ceramic products
Heat Resistance Iron Oxide Black is suitable for industrial applications where black coloration and enhanced thermal stability are required.
The pigment can be evaluated for plastics and rubber polymers requiring higher thermal stability during processing.
Its specified 600°C heat resistance provides a substantial thermal-performance margin compared with conventional iron oxide black grades, although actual suitability depends on the polymer, processing temperature, residence time, and formulation.
Heat Resistance Iron Oxide Black can be used in industrial coatings and other coating systems requiring durable black coloration.
Its lightfastness, weather resistance, and chemical resistance make it suitable for applications where long-term color stability is important.
The pigment can be used in concrete, bricks, mortar, paving tiles, roof tiles, and other construction materials requiring black or dark coloration.
Its weather resistance is particularly relevant to architectural products intended for outdoor exposure.
Heat Resistance Iron Oxide Black can be used in fiber cement products requiring stable dark coloration and resistance to environmental exposure.
The pigment can be considered for WPC applications requiring black coloration together with weather and migration resistance.
The TDS also lists ceramic products and other architectural materials among the recommended applications.
ColorCor®1826 has a specified heat resistance of 600°C, which is the defining performance characteristic of this grade.
This makes it suitable for evaluation in industrial applications where conventional iron oxide black pigments may not provide sufficient thermal stability.
The product has a specified particle size of 0.2 μm.
This fine particle size should be considered when evaluating dispersion, color development, surface appearance, and processing behavior in the target formulation.
ColorCor®1826 has a light resistance rating of 8 in both full shade and reduced tinting conditions.
This supports applications where stable black coloration is required under prolonged light exposure.
The product has a weather resistance rating of 5, making weather durability an important performance characteristic for exterior construction materials, coatings, paving products, and other outdoor applications.
ColorCor®1826 has a migration resistance rating of 5.
This makes the pigment suitable for consideration in plastic and rubber applications where migration or bleeding needs to be controlled.
The pigment has acid and alkali resistance ratings of 4, together with resistance ratings of 4 against ethyl acetate, ethanol, and MEK.
These properties allow it to be evaluated across mineral, coating, plastic, rubber, and other industrial formulation systems.
Although ColorCor®1826 has a specified heat resistance of 600°C, this value should not be interpreted as a universal processing temperature for every application.
Actual pigment stability can depend on the polymer, binder, atmosphere, residence time, heating profile, additives, and other formulation conditions.
The specified 0.2 μm particle size can be beneficial for certain applications, but fine particles require appropriate dispersion conditions to achieve consistent color development.
Dispersion equipment, processing method, pigment loading, and formulation compatibility should therefore be evaluated together.
The final appearance of the black coloration can vary according to pigment concentration, binder or polymer system, dispersion quality, and the presence of other pigments or additives.
For precise color matching, buyers should provide a target color standard or physical sample.
The 600°C TDS value provides an important reference for material selection, but actual performance in a specific end-use application should be confirmed through testing under the customer’s real processing and exposure conditions.
When sourcing Heat Resistance Iron Oxide Black, buyers should confirm the following factors.
The most important selection criterion is the actual temperature exposure.
Buyers should provide the processing temperature, peak temperature, residence time, and heating cycle so the pigment’s thermal performance can be evaluated appropriately.
ColorCor®1826 has a specified heat resistance of 600°C.
Specify whether the pigment will be used in plastics, rubber, coatings, concrete, fiber cement, WPC, ceramics, or another industrial application.
Different applications place different requirements on thermal stability, dispersion, chemical resistance, and weather durability.
If fine particle size is important to the formulation, buyers should confirm the target particle-size range.
ColorCor®1826 has a specified particle size of 0.2 μm.
For plastics, rubber, coatings, and other formulated systems, buyers should discuss the dispersion method, equipment, pigment concentration, and binder or polymer system.
For exterior applications, confirm the expected sunlight and weather exposure.
The product has light resistance of 8 and weather resistance of 5, supporting its evaluation for outdoor applications.
For applications involving acids, alkalis, or organic solvents, buyers should compare the TDS resistance ratings with their actual exposure conditions.
For international B2B projects, buyers should confirm the required TDS, SDS, CoA, product specifications, and applicable regulatory documentation before commercial purchasing.
For customers comparing different black pigment grades, Fineland Chem also offers Iron Oxide Black as a conventional grade for applications where extreme heat resistance is not the primary requirement.
Buyers can also compare the wider range of Iron Oxide Pigments and related color grades according to their application and performance requirements.
