trans-1,2-dichloroethylene

Trans-1,2-dichloroethylene (CAS 156-60-5), also known as trans-acetylene dichloride, is a chlorinated solvent used primarily for precision cleaning and degreasing in industrial settings. Its relatively low boiling point and strong solvency make it a practical choice for removing oils and greases.

This chemical is highly effective at removing flux residues from sensitive substrates without aggressive chemical attack. In electronics manufacturing, it is used to clean printed circuit boards and precision components where residue-free surfaces are critical to performance.

Metalworking operations use it as a degreasing solvent to prepare parts prior to coating, plating, or assembly. Industrial and institutional cleaning formulations incorporate it as a carrier solvent to improve the penetration and evaporation profile of cleaning concentrates.

It also appears in specialty lubricant formulations as a solvent carrier for active ingredients applied to tight-tolerance mechanical components. This versatility makes it a staple in high-performance maintenance and repair operations across various sectors.

Trans-1,2-dichloroethylene is supplied as a clear liquid in standard drum and IBC quantities. Technical grade is the primary commercial specification available for industrial solvent applications, ensuring consistent performance in large-scale manufacturing environments.

Purity levels typically range from 97% upward, with high-purity grades available for electronics and precision cleaning end uses. These specifications ensure that the solvent meets the rigorous demands of modern industrial cleaning and chemical processing standards.
