D40 is a purified, and dearomatised mineral spirit type hydrocarbon solvent.
Understanding D40 Solvent
Based on the provided information, D40 is specifically defined by its composition and purity level. It belongs to the class of mineral spirit type hydrocarbon solvents but undergoes a significant refining process that distinguishes it.
Key Characteristics of D40
The high degree of general refining is a defining feature of D40, leading to several important properties:
- Type: Mineral spirit type hydrocarbon solvent.
- Purification: It is purified and dearomatised. This means aromatic compounds, which are common in many solvents and can contribute to stronger odors and higher toxicity, have been largely removed.
- Impurity Levels: The refining process results in a low level of specific impurities.
- Odor: It has a low odor, likely a direct result of the dearomatisation and removal of other volatile impurities.
Low Levels of Impurities
The rigorous refining process ensures D40 has low levels of undesirable substances. According to the reference, these include:
- Olefins
- Sulphur
- Benzene
- Total aromatics
This high purity profile is a key aspect that differentiates D40 from less refined mineral spirits.
Summary of D40 Properties
Property | Description |
---|---|
Chemical Class | Hydrocarbon Solvent |
Type | Mineral Spirit Type |
Purity | Purified, Dearomatised, High Degree of Refining |
Impurity Levels | Low (Olefins, Sulphur, Benzene, Total Aromatics) |
Odor | Low |
In essence, D40 is a highly refined version of a common solvent type, engineered for reduced impurities and odor.
