What are Exxsol Fluids?
Exxsol Fluids are characterized as "de-aromatized" aliphatic hydrocarbons. Their major components are normal paraffins, isoparaffins and cycloparaffins. They contain very low levels of aromatic hydrocarbons.

How do Exxsol Fluids compare with traditional mineral spirits or white spirits?
Traditional mineral spirits or white spirits have aromatic concentrations generally between 10 and 25 weight percent. Exxsol Fluids have been dearomatized, and aromatic concentrations are less than about 1 weight percent. They consequently have lower odor and lower order of toxicity. However, they also have less solvency (and correspondingly better elastomeric compatibitility) relative to mineral spirits in the same volatility range.

What Exxsol Fluids does ExxonMobil Chemical market?
The Exxsol Fluid grade slate ranges from very fast evaporating hydrocarbons, such as Exxsol Isopentane, to very slow evaporating materials, such as Exxsol D130 and Exxsol D140 Fluids. In the more volatile, faster evaporating grades, the grade name includes a number that indicates the approximate boiling range in degrees centigrade. In the higher boiling grades, such as Exxsol D40 through D130 Fluids, the number indicates the approximate flash point of the product in degrees centigrade.

How do Exxsol Fluids differ in solvency?
Solvency is directly related to volatility and cycloparaffin content. Grades that have relatively higher volatility or higher cycloparaffin content provide increased solvency.

How do Exxsol Fluids differ in odor?
Aromatic and sulfur content affect the odor of all hydrocarbon fluids. Exxsol Fluids have low concentrations of aromatic and sulfur molecules and therefore have very low odor. Note that odor detection is affected by volatility. High vapor pressure fluids evaporate faster and have more noticeable odors than low vapor pressure fluids.

In what applications are Exxsol Fluids used?
Volatile Exxsol Fluids are used as reaction diluents and in adhesives and vegetable oil extraction.  Heavier Exxsol D Fluids are used in paint and coatings, pesticides, reaction diluents, waterless hand cleaners, carbonless copy paper, spark erosion machining, PVC organisols,  auto dewaxing, lubricants, process aids, industrial cleaning, PVC plastisols and water treatment.

Exxsol D40 Fluid
Exxsol D60 Fluid

Why should I use Exxsol Fluids in architectural coatings formulations?
Architectural coatings containing Exxsol fluids have lower odor, lower order of toxicity and lower photochemical reactivity (i.e., lower ozone forming potential), compared to coatings formulated with traditional mineral spirits. Low odor formulations result in fewer nuisance complaints, less interference with taste and smell during and after application and lead to more rapid re-entry of rooms after painting

Which ExxonMobil Chemical Fluids are considered naphthas?
Varnish Maker's and Painter's Naphtha (VM&P Naptha) are products that generally have higher volatility than traditional mineral spirits, making them good candidates for applications requiring fast evaporation rates or quicker drying times.  Exxsol DSP 115/145 Naphtha would be considered representative of a low aromatic type of VM&P naphtha. For users who require an improved, odorless VM&P type product, Isopar E Fluid should be considered.
