DOWPER™* MC, our virgin-grade Perchloroethylene, is highly stabilized and contains a special additive, making it an effective cleaning agent for heavy-duty applications. An ideal solution for clean parts with low surface tension (making it easy to wet into and evaporate out of tight spaces), it has a wide range of approvals in the aviation industry.

•           Its relatively high vapor temperature helps eliminate high-melting, oxidized or hardened grease and contaminants.

•           It is highly stabilized against the potential reaction with light metals, including aluminum and titanium, formulated cutting oils and their additives, as well as water humidity, which helps ensure cleaning process stability.

•           Because of its high stability, DOWPER™* MC is unaffected by boiling or distillation and can be effectively recycled via built-in distillation in closed machines. Its use makes a great example of the Circular Economy.

•           Parts cleaned with DOWPER™* MC dry quickly and completely, saving energy, time and costs.

•           It is also non-flammable.

•           DOWPER™ MC is registered for closed vapor degreasing in Europe under REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) and is NOT classed as a substance of very high concern (SVHC).

STANDARDS

•           ASTM D4376 – Standard Specification for Vapor-Degreasing Grade Perchloroethylene

•           ASTM F-945-06 – Standard Test Method for Stress

Our virgin, high-performance modified alcohols of the DOWCLENE™* 16 Series along with DUALENE™ 1601 S have diversified chemical and physical properties that can satisfy individual requirements.

All grades have a low toxicity and are chemically highly stable to ensure a secured process.

As non-halogenated solvents, they are not under further evaluation for neither REACH in Europe nor TSCA (The Toxic Substances Control Act) in the US.

With both non-polar and polar properties, they can effectively remove oils and greases but also certain polar contaminations like cooling emulsions or solids (e.g. salt, particles, abrasives).

Supported by the MAXISTAB™ S-Series Stabilizers, our modified alcohols can ensure a much more stable, predictable and safer process even when cleaning highly chlorinated oils.

STANDARDS (DOWCLENE™* 1601)

•           ASTM F 483 - Standard Practice for Total Immersion Corrosion Test

•           ASTM F 519 - Standard Test Method for Mechanical Hydrogen Embrittlement Evaluation

•           ASTM F 945 - Standard Test Method for Stress-Corrosion of Titanium

•           ASTM F 1110 - Standard Test Method for Sandwich Corrosion Test (compatible with sensitive alloys such as AL 2024 and AL 7075)

•           ASTM F 1111 - Standard Test Method for Corrosion of Low Embrittling Cadmium Plate  ASTM F 2111 - Standard Practice for Measuring Intergranular Attack or End Grain Pitting on Metals

DOWCLENE™* 1601 does not contain any declarable substances featured within the Aerospace Defence-Declarable Substance List compiled by the International Aerospace Environmental Group (IAEG).

Developed with Responsible Care® guidelines in mind, the SAFE-TAINER™ System is an active risk management measure for handling both chlorinated solvents and modified alcohols.

Used in combination with closed cleaning equipment, the SAFE-TAINER™ System is considered to be the best available technology (BAT).

The closed-loop solvent delivery system ensures the safe supply of fresh solvent and the safe return of used solvent. It can be easily connected to closed cleaning machines and allows safe and easy filling and emptying of the machine – with virtually no emission.

The SAFE-TAINER™ System helps companies meet their legal obligations to protect workers and the environment, from delivery, storage, filling and emptying the cleaning machine all the way to recycling.

From routine analyses to complex troubleshooting, our Lab Services help ensure process reliability and optimized cleaning performance.

•           CHEMAWARE™ Solvent Analysis measures the solvent quality. 

•           CHEMAWARE™ Oil Compatibility Test determines the compatibility of different oils applied in the production process with the solvent and its stabilization. 

•           CHEMAWARE™ Special Analyses are made on demand and provide you with the information needed for your own optimal cleaning process.

MAXISTAB™ S-Series Stabilizers further expand the possibilities of modified alcohols by maximizing process reliability.

The Series has been specially developed to counteract the effects of organic acids, sulphur compounds, hydrochloric acid and chlorides – and to prevent their build-up in cleaning systems. The stabilizers can enable a stable process even when cleaning highly chlorinated oils.

We offer you and your employees comprehensive solvent training courses to enable a safe, efficient and optimized solvent cleaning process.
