Solvent 100 vs Solvent 150 | High‑Flash Aromatic Solvents Explained

 What Are They?

Solvent 100 (Aromatic C9, Solvesso 100) and Solvent 150 (Aromatic C10, Solvesso 150) are high‑flash petroleum-derived aromatic solvents used extensively in paints, coatings, printing inks, pesticides, and industrial cleaning applications.

The “100” and “150” generally refer to their flash point range and boiling range: Solvent 100 has a slightly lower flash point (~46 °C) and boils around 160–180 °C, while Solvent 150 features a higher flash point (~63 °C) and distills in the 180–220 °C range.

 Composition & Properties

• Solvent 100 (C9 Aromatic):

  • Distillation: ~158–170 °C

  • Aromatic content: ~99% C9 hydrocarbons (trimethylbenzenes, ethyltoluenes)

  • Flash Point: ~43–49 °C 

  • Specific Gravity: ~0.88 at 15 °C 

• Solvent 150 (C10 Aromatic):

  • Distillation: ~180–218 °C 

  • Aromatic content: ~99% C10–C11 aromatics

  • Flash Point: ~60–65 °C

  • Specific Gravity: ~0.90 at 15 °C

 Key Applications & Performance

Both solvents serve high‑solvency roles, but with different performance highlights:

• Solvent 100 is ideal when faster evaporation and stronger solvency are needed, often used in coatings and degreasing. 

• Solvent 150, due to its higher flash point and slower evaporation, is better suited for applications requiring extended open time, improved film formation, and safer handling. Frequently used in adhesives, agrochemical concentrates, varnishes, and rubber compounding.

In paint formulations, Solvent 150 provides smoother flow and slower drying than Solvent 100—beneficial in high‑quality coatings and high ambient temperature applications.

 Safety & Environmental Considerations

Solvent 150’s higher flash point (~≈63 °C) makes it safer and less volatile than Solvent 100 (~46 °C). Both meet VOC regulation standards when handled properly and used within specified application ranges.
