Our TBAc brand of tertiary butyl acetate is a unique non-HAP, VOC-exempt* organic solvent with versatile performance and negligible photochemical reactivity. It is designed to solve many of the compliance issues facing manufacturers and end-users of formulated products.
Benefits and Applications
A versatile oxygenated solvent offering a unique physical property profile, TBAc solvent can be used alone or in solvent blends in applications including coatings, inks, adhesives, industrial cleaners and degreasers. Whether incorporated during resin production or in formulation of the final product, TBAc solvent provides effective performance in a wide range of technologies, resulting in significant reductions in VOC and HAP content.
In October, 2010, an Environmental Security and Technology Certification Program (ESTCP) report was issued by the U.S. Department of Defense (DoD) regarding the use of TBAC in MIL-spec applications. After exhaustive testing, TBAc solvent was found to effectively clean dirt, grease, soot, paint debris and burned-on carbon from vehicles and equipment before painting operations, while providing leading environmental and cost benefits. Based on process parameters developed in lab evaluations and bench-scale tests, full-scale testing was performed at the Corpus Christi Army Depot (CCAD) in Texas, the Norfolk Naval Shipyard in Virginia and the Marine Corps Logistics Base in Albany, Georgia.
The physical properties of TBAc solvent set it apart from other VOC-exempt solvents: broad solvency range, an intermediate evaporation rate, low density and a flash point well within accepted industry parameters. This combination of properties, in conjunction with its VOC-exempt and non-HAP status, are key to the versatility of TBAc solvent.
Manufacturers of formulated products in almost all markets are under increasing pressure to reduce VOCs and HAPs and to develop formulations with lower overall environmental impact. TBAc solvent can be used to bring current formulations into compliance with Section 183(e), Federal VOC content limits, MACT HAP content limits, state-adopted CTG limits or local emission restrictions with minimal reformulation effort and no additional capital expenditures. TBAc solvent is also VOC-exempt under Green Seal standards GS-36 (adhesives and sealants), GS-47 (stains and finishes), and GS-11 (Paints & Coatings).
The unique combination of properties of TBAc solvent makes it an ideal candidate for solvent substitution in many applications. Used alone or in blends, it is a potential substitute for a variety of HAP solvents and VOCs including aromatics (toluene and xylene), ketones (MEK, MIBK), and other esters as well as ozone depleters such as methyl chloroform, CFC-113, and 1,1,1 T.
TBAc solvent exhibits low health hazard potential. Unlike many other solvents, it is only slightly irritating to the eyes and skin. TBAc solvent did not cause allergic reactions following repeated exposures. It was not toxic by inhalation or skin absorption and only slightly toxic by ingestion.

*TBAC is now VOC-exempt in Canada (architectural and automotive coatings) and most of the United States. Please check with your state and local regulatory agencies to ensure that they recognize the US EPA VOC definition in 40 C.F.R. § 51.100(s)(5); see also 69 FR 69304. View the EPA ruling.

TBAC is also VOC-exempt in 20 California counties and partially exempt in five others. Another 15 counties are in attainment for ozone and do not regulate VOCs. The California Air Resources Board (CARB) has not yet exempted TBAC in its Consumer Products regulations.

TBAc is on the US TSCA list and the EEC EINECS, Canadian DSL, and on the Australian, Korean, Philippine, Japanese and Chinese chemical inventories. Refer to the Material Safety Data Sheet for more detailed information or email firstname.lastname@example.org.
TBAc solvent has been shown to biodegrade in standard closed-bottle laboratory tests using acclimated and non-acclimated microorganisms. 28-day biological oxygen demand (BOD) expressed as % of chemical oxygen demand (COD) ranged from 28% with EPA-approved Polyseed to 75% with acclimated Delcora sludge typically found in Publicly-Owned Treatment Works (POTW). Chemicals with BOD greater than 60% of their COD are generally considered to be "readily biodegradable." TBAc is, therefore, either readily or inherently biodegradable, depending on the microorganisms present.
Storage and Handling
Handle empty containers carefully. Store in properly lined steel or stainless steel to avoid slight discoloration from mild steel. This product may absorb water if exposed to air. TBAc solvent has a flash point of 40°F (4.4°C). It is a flammable liquid as defined under SARA Title
III, section 311/312 hazard category but is not subject to the reporting requirements of SARA Title III, section 313.
Undue exposure or spillage should be strictly avoided as a matter of good practice. Refer to the Material Safety Data Sheet for more specific information.
