SOLVENT RED 161

Solvent Red BXL is a single phase, liquid concentrated solvent soluble dye containing C.I. Solvent Red 164 and provided in a xylene solvent system. The solvent is used in the product as a viscosity depressant and standardizing agent. The product has been found to be completely miscible in all petroleum fuels, lubricating oils and many other related hydrocarbon solvents, including grease and hydraulic oils. Common applications include the coloration of fuels such as diesel fuels designated for tax-exempt applications. It has also found use in a variety of other applications including the coloration of lubricants, solvents and explosives, as well as for leak detection. It can be mixed with other colors in the product line to create a seemingly limitless variety of shades.

Handling Precautions

Solvent Red BXL has been formulated to accommodate handling at temperatures down to 0°C. To ensure pumpability at temperatures below this we recommend diluting the product with an aromatic solvent. Any piping, fittings, valves, filters, metering pumps, etc. should have wetted parts compatible with that of a xylene solvent system.

Before using this product, consult the Safety Data Sheet (SDS) for details on product hazards, first aid measures, recommended handling precautions, recommended personal protection equipment and product storage.

CAUTION! Keep combustible and/or flammable products and their vapors away from heat, sparks, flames and other sources of ignition including static discharge. Processing or operating at temperatures near or above product flashpoint may pose a fire hazard. Use appropriate grounding and bonding techniques to manage static discharge hazards.

Storage

The recommended storage temperature for this material is between 10 and 40°C. Exposure to excessively low temperatures should be avoided as it may cause increased levels of precipitation. The product is flammable with a low flash point. Therefore it should be stored away from excessive heat sources and all potential ignition sources. All metal containers should be grounded during storage, handling and transfer. If product containers are kept sealed and dry and extreme temperatures are avoided the shelf life of the material is greater than 3 years. The container should be tightly closed when not in use in order to prevent solvent evaporation.

Disposal Considerations

Dispose in accordance with all local, state (provincial) and federal regulations. Empty containers may contain hazardous residues. This material and its container must be disposed in a safe and legal manner. It is the user’s responsibility to verify that treatment and disposal procedures comply with local, state (provincial) and federal regulations.
