Product Overview

Dow Trichloroethylene (TCE, CAS 79-01-6) is a clear, nonflammable chlorinated solvent valued for its strong solvency and high vapour density. It is supplied as Dow TCE degreasing grade for metal cleaning and as Dow HI-TRI™ Trichloroethylene for high-purity process use.

As a versatile chlorinated hydrocarbon, it dissolves oils, greases, waxes and many organic residues while remaining stable toward common metals. Commercial grades are supplied with inhibitor systems that protect both the solvent and the equipment in which it is used.

Available Grades

Two Dow presentations cover the main industrial requirements for trichloroethylene.

Degreasing Grade

Dow TCE Degreasing Grade

Formulated for vapour degreasing and cold cleaning of fabricated metal parts. Its strong solvency removes drawing oils, cutting fluids, greases and buffing compounds, while the high vapour density supports efficient condensing rinsing in degreasing equipment.

High Purity

Dow HI-TRI™ Trichloroethylene

A high-purity TCE grade suited to specialised extraction processes that demand consistent solvent quality, such as lead-acid battery separator manufacture and caprolactam production. With suitable stabiliser concentrates it also delivers high-performance metal cleaning with limited risk of corrosion, oxidation, staining or pitting.

Dow HI-TRI Trichloroethylene

Applications

Trichloroethylene is a long-established solvent across precision cleaning and extraction operations.

  • Vapour degreasing of fabricated metal parts in automotive, aerospace and general engineering.
  • Cold cleaning of machinery components, bearings and assembled units.
  • Extraction solvent for lead-acid battery separators and caprolactam production.
  • Electronic component and precision parts cleaning.
  • Process solvent in polymer modification and laboratory use.
