Solvent C-9 Aromatic Aromatic > 98%
Composition: C9 Alkylbenzenes

Solvent C-9

High Boiling Aromatic Hydrocarbon (Aromatic 100)

Solvent C-9 is a clear, colorless liquid with a characteristic aromatic odor. It is a mixture of hydrocarbons with 9 carbon atoms (Propylbenzenes, Trimethylbenzenes). Unlike Xylene or Toluene, C-9 has a higher boiling point and slower evaporation rate, making it essential for high-gloss paints and agrochemical formulations where rapid drying is not desired.

CAS Number 64742-95-6
Distillation Range 160°C - 180°C
Aromatic Content 98% Min

Product Overview

Solvent C-9 is often referred to as "Aromatic 100." It has excellent solvency for synthetic resins like alkyds, acrylics, and epoxies. Its high KB value (Kauri-Butanol > 90) means it can dissolve heavy resins that mineral spirits cannot.

  • Flow & Leveling: Its slow evaporation allows the paint film to settle smoothly, removing brush marks and creating a mirror-like finish.
  • High Flash Point: With a flash point > 40°C, it is safer to handle and transport compared to Toluene or Xylene.
  • Agro-Friendly: Highly effective in dissolving pesticide active ingredients for Emulsifiable Concentrates (EC).

Mechanism: The "Evaporation Tail"

Why use C-9 instead of Xylene?

Paint drying is a race. If the solvent leaves too fast (like Xylene in hot summer), the paint dries before it can flatten out, leaving rough brush marks or "Orange Peel."

  • The Tail Solvent: C-9 is a "Tail Solvent." It stays in the paint film till the very end. This keeps the film fluid for 10-15 minutes longer.
  • The Result: Gravity has time to pull the paint flat. Bubbles escape. The result is a smooth, defect-free, high-gloss surface essential for automotive refinishes and industrial coatings.

Industrial Applications

Paints & Coatings

High gloss enamels, varnishes, and marine coatings where slow drying is required.

Agrochemicals

Solvent for herbicides and pesticides. Its high aromaticity dissolves difficult active ingredients easily.

Printing Inks

Used in screen printing and offset inks to retard drying and prevent screen clogging.

Automotive Refinish

Used in car PU paints to ensure a premium finish without pinholes or blushing.

Industrial Cleaning

Heavy-duty degreaser for cleaning machinery parts, engines, and removing tar/asphalt.

Oilfield Chemicals

Used in the formulation of corrosion inhibitors and demulsifiers for crude oil.

Packaging Options

185 KG MS Drums

Standard heavy-duty steel drums. Reconditioned or New.

Road Tanker / ISO Tank

Bulk supply (18-20 MT) for large paint factories.

Safety & Handling Protocols

Flammable Liquid

Solvent C-9 is a Class 3 Flammable Liquid (Flash Point ~42°C).

  • Skin Contact: Repeated exposure may cause skin dryness or cracking. Use Nitrile/Viton gloves.
  • Environment: Toxic to aquatic life with long-lasting effects. Prevent spillage into drains.
  • Storage: Store in a cool, well-ventilated place away from sunlight and ignition sources.
