从India供应商批量进口Acid Red 73 - Crocein Scarlet Nbo

Crocein Scarlet Nbo is the commercial designation for Acid Red 73 supplied by Karsandas Mavji, a Mumbai-based operation in Maharashtra, India. This acid dye variant is formulated for application across protein and polyamide substrates including wool, silk, nylon, and extends to leather, paper, and ink systems. The Nbo suffix typically indicates a specific physical form or manufacturing process variation within the Acid Red 73 colour index family, though buyers should confirm the exact specification with the supplier.

The dye's formulation relies on azo chemistry with optimised sulfonic acid content for broad substrate compatibility. Crocein Scarlet variants in the acid dye range generally exhibit good levelling properties on wool at pH 4.0-5.5, with controlled migration enabling level coverage on substrates with irregular dye affinity. For nylon applications, the dye shows moderate wet fastness without after-treatment, improved through synthesis with specific counterions or post-dyeing fixation processes. Paper and leather applications require adjusted solubility profiles to prevent backwater staining or uneven penetration in vegetable-tanned substrates.

Karsandas Mavji positions this dye for industrial colouration where multi-substrate application flexibility is valued over maximum fastness on any single material. Buyers in the hosiery, carpet, and specialty paper sectors should evaluate Crocein Scarlet Nbo against their specific performance criteria, particularly wet fastness requirements for nylon swimwear or perspiration fastness for wool activewear. The supplier's harbour trust tier indicates baseline platform verification; response capability and technical support depth should be confirmed directly before commitment.

Karsandas Mavji operates from 203 Rangwala Apartments, M.G. Road, Ghatkopar West, Mumbai, Maharashtra, India, postal code 400086. The supplier holds a harbour trust tier on the platform. The response rate is recorded at 0.00% with zero average response hours, indicating no recent platform-mediated communication activity.

The company describes itself as among prominent entities engaged in acid dye manufacturing in India, with formulation using acids and compounds procured from certified market vendors. The listing provides no information about year of establishment, manufacturing facility certification, environmental compliance, production scale, or specific export experience. No quality management system accreditations, laboratory capabilities, or proprietary formulation expertise are mentioned. Buyers should verify directly whether Karsandas Mavji maintains ISO 9001 or ISO 14001 certification, and whether they operate their own manufacturing or function as a formulator using purchased intermediates.
