DESCRIPTION

Raven 1040 is a commercial specialty carbon black grade manufactured for pigment applications.
Chemically, Raven 1040 consists predominantly of elemental carbon arranged in engineered particulate aggregates rather than individual molecular units.

For this reason, Raven 1040 does not possess a single defined molecular formula or fixed molecular weight in the conventional chemical sense.
The formula C and atomic weight of 12.01 g/mol describe elemental carbon only and do not represent the full particulate structure of the commercial product.

Raven 1040 is produced through controlled high-temperature decomposition or partial combustion of hydrocarbon feedstocks.
During production, very small carbon particles form in the gas phase and fuse into three-dimensional aggregates.

These aggregates can subsequently associate into larger agglomerates during manufacture, storage, and handling.
The pigment, Raven 1040, is supplied in powder or bead form, depending on the commercial grade and regional product offering.

Powder forms of Raven 1040 generally provide rapid incorporation, whereas bead forms can improve bulk handling and reduce uncontrolled dust release.

Raven 1040 undergoes surface oxidation or post-treatment to introduce oxygen-containing functional groups onto the carbon surface.

This treatment produces an acidic surface character, as indicated by the typical aqueous pH range of 3.0–3.5.

Raven 1040's modified surface chemistry can improve wetting, dispersion stability, flow, and compatibility in suitable ink and coating vehicles.

Raven 1040 has a statistical thickness surface area of approximately 86 m²/g, placing it within the medium-color specialty carbon black range.

Raven 1040's oil absorption number of approximately 100 cm³/100 g reflects the aggregate structure and the amount of liquid required to fill interaggregate voids.

The combination of surface area and structure influences pigment loading, viscosity, tint strength, gloss, and dispersibility.

A typical ASTM tinting strength value of approximately 115 demonstrates its ability to darken white or colored pigment systems.
The reported Hunter L value of approximately 80 characterizes its medium-color masstone performance under the specified test system.

The negative Hunter b value of approximately −7.5 indicates a blue rather than brown undertone.
Raven 1040 contains approximately 2.6% volatile matter under the referenced test conditions, largely reflecting oxygen-containing surface groups and adsorbed volatile components.

Raven 1040 is insoluble in water and common organic solvents because it is a particulate carbon material rather than a soluble molecular substance.
Nevertheless, Raven 1040 can be dispersed throughout liquid vehicles and polymer matrices by mechanical energy combined with suitable wetting agents.

Effective dispersion separates agglomerates and distributes the carbon black aggregates uniformly throughout the formulation.
Insufficient dispersion can reduce color strength, gloss, flow, storage stability, and surface uniformity.

Excessive milling may also alter formulation rheology or introduce unnecessary heat, making controlled processing essential.
The optimum dispersant, resin, solvent, pigment loading, and milling conditions should therefore be established through formulation testing.

Raven 1040 is chemically stable under ordinary storage and processing conditions and is not expected to undergo rapid degradation.
Raven 1040's black color and resistance to ordinary light exposure provide excellent permanence compared with many organic black colorants.

Raven 1040 can absorb moisture from humid environments, which may influence handling and dispersion behavior even though carbon black itself does not dissolve in water.
Properly stored carbon black has an effectively indefinite shelf life when protected from liquid water, excessive humidity, contamination, and unsuitable storage conditions.

FIRST AID

Inhalation: Move the affected person away from the dust source and into fresh air. Keep the person at rest and monitor for coughing, wheezing, respiratory irritation, or breathing difficulty. Obtain medical attention if symptoms persist or significant exposure has occurred.

Skin Contact: Wash the affected skin thoroughly with soap and water. Remove contaminated clothing and clean it before reuse. Carbon black may cause mechanical drying or irritation; seek medical advice if discomfort, redness, or irritation continues.

Eye Contact: Rinse the eyes cautiously with clean water for at least 15 minutes while holding the eyelids open. Remove contact lenses when present and easy to do, then continue rinsing. Avoid rubbing the eyes because solid particles may cause mechanical irritation. Obtain medical attention if irritation persists.

Ingestion: Rinse the mouth with water. Do not induce vomiting unless instructed by qualified medical personnel. Carbon black is not expected to present a significant acute ingestion hazard under normal industrial conditions, but medical advice should be obtained if a large amount is swallowed or symptoms develop.

Note to Physicians: Treat symptomatically and provide supportive care. Exposure is generally associated with mechanical irritation from dust rather than systemic chemical toxicity. Consult the current regional Safety Data Sheet supplied by  for product-specific and jurisdiction-specific medical information.

HANDLING AND STORAGE

Handling: Avoid generating airborne dust during bag opening, transfer, weighing, mixing, and dispersion. Handle the product using enclosed systems, controlled feeding equipment, or other methods that minimize dust release. Do not breathe dust and avoid unnecessary contact with the eyes and skin. Do not use compressed air to remove deposited carbon black from equipment, clothing, or work surfaces.

Ventilation: Provide effective general ventilation and local exhaust at points where dust may be generated. Process enclosures and dust-collection systems should be designed to maintain airborne carbon black below applicable occupational exposure limits. Use suitable respiratory protection when engineering controls cannot adequately control exposure.

Storage: Store in a cool, dry, and well-ventilated location. Protect bags and containers from liquid water, high humidity, contamination, excessive heat, and direct contact with strong oxidizing agents. Keep packaging closed until the material is required. Maintain good housekeeping and prevent large accumulations of carbon black dust on floors, ledges, beams, and equipment.

Spill and Leak Procedures: Eliminate unnecessary ignition sources and restrict access to the affected area. Avoid actions that disperse dust into the air. Collect spilled material with an industrial vacuum equipped with suitable filtration or use another low-dust recovery method. Do not use compressed air or vigorous dry sweeping. Transfer the recovered material into labeled containers for reuse or disposal in accordance with local regulations.

Handling Precautions: Take precautionary measures against static discharge and electrically ground suitable transfer and processing equipment. Keep carbon black dust away from flames, sparks, hot surfaces, and other ignition sources. Wear safety glasses or goggles, protective gloves, appropriate work clothing, and respiratory protection selected through a workplace risk assessment. Wash thoroughly after handling and consult the current Safety Data Sheet before industrial use.
