# Solstice® 

# PF – The Next Generation Solvent Performance  Excellent Solvency for a Wide Variety of Solutes ( Oils and Greases, Solder Fluxes, etc. )  Low Surface Tension for Precision Cleaning: Improved wetting characteristics 

## Environmental  Meets or Exceeds Regulatory and Safety Requirements GWP = 1 Very Short Atmospheric Life Time: 26 days Doesn’t Contribute to SMOG due to Very Low MIR (POCP) 

## Safe  Non - Flammable, as established by ASTM E-681  Good OEL – 800 ppm (OARS WEEL) 

## Cost Effective  Reduced Energy Requirements for Processing and Drying  Can be recovered by Activated Carbon Recovery or Distillation Processes  No Post Process NVR (non -volatile residue) Removal 

## Equipment Compatibility – Can be used in most Vapor Degreaser Configurations  Enclosed  Open Top 

## Suitable Replacement  TCE 

###  n - bromopropane ( nPB) – toxicity issues, NIOSH/OSHA, Hazard Alerts 8/16/2013  AK 225 – mandate phase-out by 1/1/2015  Stoddard Solvents – flammability issues  Vertrel (DuPont) and Novec (3M) – high GWP

# What do the OEL levels mean

TCE OEL = 10 ppm

NPB OEL = 0.1 ppm

PF OEL = 800 ppm Calculations  

### Assume a 400 ft sq room.  

### How many mL of solvent could be dripped on the floor 

### before reaching the OEL. NPB  

### After the first few drops you could have issues. TCE  

### Take about ~70 drops to reach the OEL 

## PF  

## Take about ~6200 drops to reach the OEL
Additional Engineering controls such as ventilation further reduce the exposure rate 

## The OEL Solstice PF is much higher than that of TCE and NPB.

# Solstice PF – Cleaning Comparison

Mobile 600 W Silicone Grease NuCalgon Mineral Oil 

## Dirty Parts

Cleaned 

# with TCE
Cleaned with PF 3 1⁄2 min immersion in boil sump followed by 40 sec in clean sump



# Equivalent Performance to TCE

# Solstice PF – Compatibility

Solstice PF has excellent metal stability and no stabilizer are required.
