3. Applications
TBAc solvent is a VOC(volatile organic compound)-exempt, non-HAP(hazardous air pollutant), urethane-grade solvent with low
toxicity, It has excellent solvency for a variety of substances including nitrocellulose, acrylic, alkyd, polyester and urethane resins. TBAc solvent is substitute for variety of HAP and VOC
solvents including toluene, xylene, esters, ketones and hydrocarbons.
TBAc solvent has similar evaporation rate and solvency as MEK,MIBK, ethyl and propyl acetate, and toluene in a variety of coating systems, including 2K urethanes, acrylics, nitrocellulose lacquers and baking enamels. Because of its superior resistance to amines, TBAc solvent can also be used in epoxy polyamide coatings as replacement for toluene.
Cleaners:For solvent-based cleaning, including metal degreasing and specialized equipment cleansing, TBAc solvent improves the cleaning efficiency of toluene, mineral spirits and acetone on baked-on greasy soil and lithium grease. TBAc solvent is non-halogenated and cannot deplete the ozone layer. TBAc solvent shows very broad solvency. Its solvency characteristics generally match those of chlorinated solvents and hydrocarbons.
Electronics:Another area where TBAc solvent may replace other solvents is in photoresist formulations used in semiconductor processing. In these processes, it is used in positive photoresist formulations. TBAc solvent may also be used in solvent systems for cleaning and degreasing circuit boards and removing solder flux.
Other Applications:The properties listed in the previous section also support the use of TBAc solvent in agricultural and textile products. It is useful intermediate in the pharmaceutical industry.
4. Storage and handling
Storage condition:
Keep container closed. Store in a cool, dark, well ventilated place. Store must be locked. Keep away from incompatible materials such as oxidizer storage.
Handling measures:
Good ventilation in the treatment. Wear suitable protective equipment. Smoke prevention. Keep away from heat / sparks / fire / hot surfaces. Prohibit smoking。Take measures to prevent the accumulation of static electricity. Use explosion-proof equipment. Thoroughly wash hands and face after treatment.

tert-Butyl Acetate Cleaning Solvent is the most effective solvent for cleaning polished metals without dulling the polished surface.
This solvent is recommended for cleaning and removal of oils, polishing rouge and contaminants from a metal substrate prior to coating with Cerakote Clear Coatings.
Liberally and repeatedly flood the substrate with tert-butyl acetate
and then wipe with a clean lint-free, micro fiber rag. This process should be repeated, flooding the surface with tert-butyl acetate and then wiping with a clean lint free, micro fiber rag, until
no residue is observed on rag.
This product is VOC exempt and is shipped in gallon quantities.
