Safety Data Sheet |
Description: TBAc solvent is Lyondell Chemical Company’s brand of tert-butyl acetate, a VOC (volatile organic compound)-exempt1, non-HAP (hazardous air pollutant), urethane-grade solvent with low toxicity. It has a characteristic ester odor. It is soluble in water to the extent of 0.8% at 23°C. It has excellent solvency for a variety of substances including nitrocellulose, acrylic, alkyd, polyester and urethane resins. TBAc solvent is a substitute for a number of HAP and VOC solvents including toluene, xylene, esters, ketones and hydrocarbons.
Applications
Coatings, Inks, Adhesives: TBAc solvent is useful in decorative and industrial coating formulations, packaging inks and pressure-sensitive adhesives. It is a used in the creation of VOC- and HAP-compliant coatings, inks and adhesives. TBAc solvent is less volatile and flammable than exempt acetone and methyl acetate.
TBAc solvent shares a similar evaporation rate and solvency with MEK, MIBK, ethyl and propyl acetate, and toluene. Because of its superior resistance to amines, TBAc solvent is also used in epoxy polyamide coatings as a replacement for toluene.
Cleaners: For solvent-based cleaning, metal degreasing, and specialized equipment cleansing, TBAc solvent increases the cleaning efficiency of toluene, mineral spirits, and acetone on baked-on greasy soil and lithium grease. TBAc solvent is non-halogenated and therefore cannot deplete the ozone layer. TBAc solvent shows very broad solvency. Its solvency characteristics are generally equivalent to 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 often 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. This product is a useful intermediate in the pharmaceutical industry.
