Sophistication and Durability: Highchemie Dyes for Premium Leather

Highchemie-brand dyes, distributed by PROQUINSA, are formulated with high-purity organic and inorganic pigments designed for industrial leather dyeing and finishing processes. Their composition ensures high thermal stability, chemical resistance, and compatibility with various leather matrices, including both natural and synthetic ones.

1. Main technical properties

• Gloss and leveling

The dyestuffs offer excellent surface gloss and high leveling capacity, enabling the production of uniform films free from stains, with good penetration into the leather fibers.

• Dyeing power and concentration

They have a high concentration, which guarantees superior dyeing power. This high concentration allows for lower formulation doses, maintaining color intensity and saturation while optimizing cost per meter produced.

• Light and heat stability

Highchemie colorants have high light fastness (UV) and heat resistance values, ensuring color permanence in applications exposed to solar radiation or high temperatures during the drying and finishing process.

• Chemical resistance

Its formulation offers excellent resistance to common agents in the leather industry, such as:

• wet and dry friction,
• perspiration,
• oils and greases,
• humidity,
• acid or alkaline solutions within the usual dyeing range.

• Flexibility and mechanical compatibility

The dyes integrate seamlessly with the leather’s fibrous structure, preserving its flexibility, elongation, and resistance to bending. They are compatible with embossing, molding, and stitching processes.

• Adhesion and penetration

They ensure excellent penetration into the substrate, preventing color migration, stains, or undesired transfers to textiles or other surfaces in contact.

• Safety and regulatory compliance

Highchemie dyes comply with international regulations applicable to the leather sector, including safety guidelines for handling, traceability, and environmental requirements.

2. Industrial Applications

Highchemie dyestuffs are designed for multiple production segments:

• Footwear and leather goods manufacturing
• Automotive and residential upholstery leather
• Apparel and accessories
• Synthetic leather (PU, PVC)

• Restoration and industrial reconditioning of leather products.

3. Operational advantages for production plants

• Reproducible and stable process: low batch-to-batch variability.

• High yield: lower dyestuff consumption to achieve the same intensities.
• Compatibility with aqueous systems and with solvents, as required.
• Excellent dispersion: avoids agglomeration and facilitates incorporation into the dye bath.
• Versatility: suitable for immersion, manual application, spraying, or roller techniques.
• Optimized costs due to its high concentration and durability.

4. Recomendaciones técnicas de uso

• Pretreatment: Clean the surface to remove any waxes, oils, or other contaminants that could affect adhesion.

• Shade test: Verify the shade’s stability in a hidden area before completing the staining.
• Mixing conditions: Respect the manufacturer’s proportions to ensure a homogeneous dispersion.
• Application: Use thin and uniform coats. If more intensity is required, apply multiple controlled coats.
• Drying: Maintain adequate temperature and air circulation conditions to ensure optimum fixation.
• Storage: Store in cool, dry areas protected from light. Keep containers tightly closed.
