Based on the results of this research, it appears that the terpenes would be the most promising substitutes. In particular, the CitriSafe product (cleaner #15) appears to work well on all four resins, with the possible exception of resin #2 in which the hand wipe time exceeded 5 minutes.
To identify a suitable, non- or less-toxic substitute cleaner for toluene and toluene-based solvents for this industry sector.
Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.

Project Number 2
Summary:
Two trials were conducted. The lab found that Solsafe 245, Citriburst 7, Citrikleen XPC, Shopmaster FF and Beyond 2006 are all capable of removing the dried coating from the ceramic coupons through agitation and manual wiping.
To identify an alternative cleaner for removing toluene based resin coating
Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
Determine a safer alternative for cleaning applications to remove solvent-based coatings using Hansen Solubility Parameters in Practice (HSPiP) off stainless steel surfaces.
Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary.
To evaluate the effectiveness of a solvent and aqueous based cleaners on the removal of acrylic and silicone adhesives from stainless steel coupons using unheated and heated immersion as a replacement for NMP.
To evaluate the effectiveness of a solvent and aqueous based cleaners on the removal of silicone adhesives from stainless steel coupons using heated ultrasonics to replace NMP.
Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
To evaluate the effectiveness of spot cleaning a stainless steel surface with a solvent to remove acrylic and silicone adhesives.
Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
Pilot testing of selected solvents for removal of adhesives.
Test showed little or no promise.
