Preptone – Low VOC Handwipe Solvent

PREPTONE is a rapidly evaporating solvent system that utilizes Ultra Prep® terpene solvent technology. It features a precise blend of ultra-high purity d-limonene (UltraPrep) in an acetone base. This product merges the benefits of both solvents, with a proprietary inhibitor that safeguards the terpene from oxidation. PREPTONE mimics the "feel" of fast-evaporating solvents like TCE and MEK. Due to its terpene solvents, its performance surpasses most ketone solvents. Additionally, since the acetone component is VOC exempt, the vapor pressure and total VOC content are below many regulatory thresholds. PREPTONE is free from halogenated components, HAPs, and ozone-depleting solvents. It is compatible with all metals and some plastics, but few elastomers. It is not recommended for painted surfaces that may not be compatible with acetone.  

Evaporation Rate – PREPTONE MEK Alternative vs. MIBK:

 

PREPTONE and MIBK have similar drying times, but their drying profiles differ. Lab tests indicate that both solvents evaporate in about 90 minutes under identical conditions (glass evaporating dish, static air, 30°C). However, PREPTONE evaporates more quickly initially. In double-wipe tests, PREPTONE outperforms MIBK in dry time and has lower total VOC emissions.

 

Benefits of Preptone:

 

• Strong solvency and ultra-clean evaporation
• Non-polar solvency for difficult soils like sealants, lubricants, and waxes
  • Ideal for pre-paint cleaning
• Vapor pressure of non-exempt component is well below the 45mmHg limit for aerospace applications
• Fast evaporation with traditional MEK and TCE "feel"
• Synergistic polar solvency of acetone and d-limonene, resulting in broad-spectrum solvency
• VOC exempt acetone
  • Easy VOC compliance with PREPTONE

 

Safety and Handling Precautions:

 

PREPTONE is a flammable material which should never be used around open flames, (welding torches, for example). Containers should be stored in a cool place. The SDS contains complete environmental, safety and health data. Please read the MSDS prior to using this material.
