Solvent Blue 70 for Inks, Wood Stains and Coatings | CAS 12237-24-0
Product Overview
Solvent Blue 70 is a colourant for solvent-containing ink and coating formulations. Its established applications include transparent wood finishes, printing inks, aluminium foil colouring, hot stamping foil coatings and leather finishing systems.
The purchasing focus is colour strength, shade and solubility in the intended solvent blend. For repeat orders or replacement projects, an existing colour standard and the actual resin system provide a more useful starting point than the powder colour alone.
Unilong accepts enquiries for industrial purchasing, sample assessment and bulk orders. Send the application, estimated quantity and delivery destination so the quotation can address the required grade and packing.
Technical Specifications
For a quotation against the reference profile below, send your solvent system and required quantity. This is an enquiry profile, not a guaranteed Unilong specification; the offered-grade limits and test methods are stated in the quotation.
| Test item | Reference profile for quotation |
|---|---|
| Appearance | Blue powder |
| Relative dyeing strength | 98–102% against a reference standard |
| Moisture | 2.0% maximum |
| Solubility in MEK | 300 g/L minimum at 20°C |
| Insoluble matter in MEK | 1.0% maximum, tested at 100 g/L and 20°C |
| Shade | Against the agreed colour standard |
If your purchasing specification uses another solvent or a different strength standard, attach it to the enquiry. A quotation can then be prepared against your requirements rather than an assumed universal grade.
Solvent Compatibility
Solvent Blue 70 is used in formulations containing alcohols, ketones and glycol ethers. Solubility varies with the particular solvent and commercial grade, so the working solvent blend is a key part of product selection.
The MEK reference above relates to a defined test condition. It does not describe the dye concentration attainable in every resin solution. For ink concentrates and coating systems, include the solvent composition and intended dye concentration in your enquiry.
Colour in the finished film also depends on the resin, substrate and application thickness. A sample in the actual formulation provides the relevant shade reference for production purchasing.
Industrial Applications
Printing Inks
Solvent Blue 70 is used as a blue colourant in solvent-based printing inks and selected stationery ink formulations. It is relevant to ink manufacturers sourcing a soluble dye for clear or transparent colour systems.
Solvent composition, concentrate strength and binder compatibility determine its fit in a particular ink. For replacement enquiries, send the current dye reference and intended ink system so shade and concentration requirements are clear.
Wood Stains and Wood Coatings
This dye is used in coloured wood stains and wood coating systems. Transparent colour is useful in finishes where the underlying wood grain remains part of the appearance.
The same colour solution can appear different on different wood species or under different topcoats. For a wood-finishing enquiry, identify the substrate and whether the colour is introduced through a stain or coating.
Aluminium Foil and Hot Stamping Foil Colouring
Solvent Blue 70 is used in colour layers for aluminium foil and hot stamping foil. These applications concern formulated colour coatings on foil rather than the bulk colouring of aluminium.
The coating resin, solvent blend and processing conditions influence the finished appearance. Send the intended foil coating system and operating conditions when requesting a sample or quotation.
Industrial Coatings and Plastic Surface Coatings
Applications include resin paints, industrial finishes and coatings applied to plastic surfaces. The dye contributes colour within a compatible coating formulation.
Plastic surface coating and melt colouring are different applications. For coating projects, specify the binder and curing conditions. For extrusion or injection moulding enquiries, include the polymer and processing temperature so the request can be assessed separately.
Leather Finishes
Solvent Blue 70 is used in leather finishing formulations to introduce blue colour into a compatible finishing layer. The finish formulation and substrate determine the resulting appearance and performance.
Include the finishing resin and relevant rubbing or colour-transfer requirements in your enquiry. These details distinguish a surface-finishing request from a general leather-dyeing enquiry.
Request a Quote for Your Ink or Coating System
Send your solvent blend, colour standard and estimated quantity to discuss the appropriate quotation basis.
Packaging, Storage & Commercial Supply
For bulk pricing, request a quotation based on 25 kg drums or 25 kg cartons. The final container, net weight and packing arrangement are specified in the quotation. These enquiry options do not establish a fixed minimum order.
Unilong’s general shipment guidance is normally 7–15 days after order confirmation. Product availability, packing and the agreed shipping arrangement determine the schedule for a specific order. Request the current dispatch date with your quotation.
Keep the powder in tightly closed packaging in a cool storage area. Use the storage and handling instructions in the SDS supplied for the offered grade; shelf life is confirmed with the product documentation.
Product Documents
Include current TDS, SDS and lot-specific COA requirements in your enquiry. Document availability and applicable versions are confirmed for the offered grade and order.
For a specification-based purchase, attach your required test items and acceptance limits. Destination-specific document requests should identify the country and the required document scope.
Frequently Asked Questions
Can I request a sample before a bulk order?
Yes. Send the sample quantity, application and delivery destination. Availability, sample charges and courier arrangements are confirmed for the request.
How is pricing calculated for a repeat order?
Provide the previous order or sample reference, required quantity and delivery destination. Any change in the specification or packing should be included in the new enquiry.
Can I enquire using an existing commercial dye reference?
Yes. Include the trade name, colour standard and working solvent system. Brand equivalence is assessed for the application rather than assumed from a similar product name.
What information is needed for a replacement enquiry?
Send the current specification, solvent and resin system, target shade and annual or order quantity. A reference sample is useful when shade matching is part of the request.
