MIL-PRF 680: Same Strength Without the Harmful Hazardous Air Pollutants

April 16, 2012 | Comments: 0 | Views: 105

Solvents dissolve substances such as solids or liquids from the surface of an item at a set temperature. Organic agents melt another substance to form a solution with evenly distributed molecules that prevents residue. Compounds used in these agents have varying solubility levels and specific properties must be taken into account when selecting these solutions for industrial use. The following are the most important qualities to take into consideration:

  • Boiling Point
  • Density
  • Volatility
  • Environmental Impact
  • Health Risks

The boiling point determines how quickly a solvent will evaporate and the temperature required for this occurrence. For example, acetone has a low flashpoint, meaning it evaporates in a matter of seconds. Organic solvents with a high flashpoint like aqueous based products require higher temperatures for evaporation to occur. This property is broken down into three categories: 

  • Low - Below 100 Degrees Celsius
  • Medium - 100 to 150 Degrees Celsius
  • High - Above 150 Degrees Celsius

MIL-PRF 680falls into multiple categories and is a maintenance degreasing solvent used for equipment or individual parts. Made from four versions of petroleum concentrates, this solution offers high performance when using a parts washer or immersion tank and does not contain Hazardous Air Pollutants (HAPs).

Organic Solvents: Manufacturers are Offering Safer Options

Organic solvents typically have a lower density than their aqueous counterparts. This property allows them to form a separate layer when water is in the picture. Volatility is defined as the compound's ability to evaporate under normal temperature conditions. Low boiling point agents often have a higher volatility meaning vapors enter the air. Solvents like the above mentioned option do not contain HAPs in order to meet strict environmental regulations and increase usage safety. While Volatile Organic Compounds or VOC's still pose health risks, they are not harmful to the environment. Manufacturers offer various products with lower VOC counts to offer a safer cleaning atmosphere.

MIL-PRF 680NEW II, in particular, does not contain a chlorinated solvent or any other type of hazardous ingredient. It offers a high flashpoint, is odorless, and supplies comparable cleaning strength to less environmentally friendly versions. Additional benefits include the following:

  • Is Not Comprised of Water
  • Has Complete Evaporation
  • Leaves No Residue
  • Elimination of Defined Hazardous Ingredients
  • Meets Corrosion Testing Requirements

NEW II works in washers or immersion tanks, but is not suitable for pressure enclosed cabinets. It can be sprayed or wiped on surfaces for dirt, carbon, or oil removal and combined with brushing for further cleaning. This particular organic solvent has been applied in industrial, military, and aerospace environments. It comes in the form of a clear liquid with a boiling point ranging from sixty to one-hundred degrees Celsius. 

The flammable properties of organic cleaning agents are determined by their volatility. Produced vapors weigh more than air and can travel far without being diluted. Certain solvents have reduced auto ignition properties, meaning they have an increased risk of fire. Handling is important with any of these substances because they are dangerous to a person's nervous system, reproductive organs, liver, kidneys, and respiratory system. Selecting a less volatile, HAP free agent such as MIL-PRF 680 reduces these risks when degreasing is essential to maintenance practices.

Organic solvents continue to be hit with additional environmental protection regulations. MIL-PRF 680 is an option when strength cannot be jeopardized and compliance is a necessity.
