Cinnabar Red Synthetic Pigment

Cinnabar Red – Azo-Based Red Pigment

Rich red colour | Azo pigment blend | Decorative and mineral applications

TerraChrom Cinnabar Red (Rouge Cinabre) is a red pigment preparation composed of azo pigments and calcium carbonate. Its vibrant red colour makes it an attractive option for colouring compatible construction materials, decorative finishes, and creative projects.

Supplied as a fine, odourless powder, Cinnabar Red can be incorporated into suitable binders and formulations to produce colourful architectural and decorative finishes. Its final appearance depends on pigment concentration, binder composition, substrate, and application method.

Despite its traditional colour name, this product is not the naturally occurring mercury sulfide mineral cinnabar. It is an azo-based pigment mixture.

Key Features

• Rich red colour – Ideal for creating vibrant red decorative effects.

• Azo pigment preparation – A mixture of azo pigments and calcium carbonate.

• Fine powder form – Suitable for incorporation into compatible formulations.

• Versatile applications – Intended for colouring construction materials and creative projects.

• Odourless – No characteristic odour.

• Stable under normal conditions – No hazardous decomposition products are expected during normal storage and use.

Recommended Uses

• Decorative plasters, renders, and architectural finishes

• Mortar, cement, and other construction-material formulations, subject to compatibility testing

• Decorative paints and coatings using compatible binders

• Arts, crafts, and creative projects

• Custom colour development and pigment blending

Compatibility with specific binders, including lime, acrylics, oils, and resins, has not been independently established in the available technical documentation. Trial batches are recommended.

Mixing & Application

For best results, incorporate Cinnabar Red gradually into the selected binder, mixing thoroughly to achieve a uniform colour and dispersion.

For dry construction-material mixes, distribute the pigment evenly throughout the dry ingredients before introducing liquids, where appropriate for the formulation. For liquid binders, use a suitable dispersion method and verify compatibility before preparing larger quantities.

Recommended pigment dosage: No universal dosage is specified in the available technical documentation. Determine the appropriate amount through small trial batches based on the desired colour and application.

Always test the finished formulation for colour development, adhesion, stability, and durability before full-scale use. For exterior applications, assess colourfastness and weathering performance in the complete system.

Handling & Storage

Store in a tightly closed container in a dry, well-ventilated location. Avoid generating airborne dust during handling and mixing.

Use suitable eye protection and a particulate dust mask when necessary. Wash hands after handling and prevent unnecessary releases into drains and waterways.

Based on available product information, Cinnabar Red is not classified as hazardous under the Canadian Hazardous Products Regulations (HPR). Refer to the current TerraChrom Safety Data Sheet for complete safety information.
