ESTASOL™ Oxygenated Solvents

ESTASOL™ is low toxicity, biodegradable, non VOC according to its vapour pressure. ESTASOL™ is a solvent that exhibits excellent solvency.

ESTASOL™ is a mixture of refined dimethyl esters of adipic, glutaric and succinic acid characterised by its mild odour and low vapour pressure.

Why ESTASOL™?

Following increasingly strict regulation on the use of solvents in the industrial, coatings and agrochemical markets, ESTASOL™ provides a safe to handle, low toxicity, and biodegradable alternative. ESTASOL™ is a strong polar solvent that can be used as an alternative to chlorinated solvents, aromatics and ketones in cleaning and a wide range of functional fluids.

Key Properties

  • High solvency
  • High boiling
  • High flash point
  • Non flammable
  • Low vapour pressure
  • Biodegradable
  • Low toxicity

Solvency

Estasol exhibits high solvency for a broad range of resins and is compatible with most commonly used solvents. This versatility enables re-formulation to be carried out readily, resulting in immediate cost savings and lowering of toxicity.
Estasol is similar in solvency to isophorone, diacetone alcohol and 2-ethoxyethyl acetate (ethyl glycol acetate). Estasol is normally blended with other solvents to provide optimization of properties in formulations.
