tert-butyl acetate

Substance: TBAc - tert-Butyl acetate 540-88-5 Other name: Acetic acid tert-butyl ester 1. Physical and chemical properties Product name: tert-Butyl acetate CAS No.: 540-88-5 Molecular Formula: C6H12O2 Molecular Weight: 116.16 Appearance form: colorless, clear, liquid Melting/Freezing point: 62℃ Boiling point: 98℃ Flash point: 4.4℃（closed cup） Density: 0.866 g/cm3（20℃） UN No.: 1123 2. Parameters index Purity, (GC) ≥ 99.5% Water Content ≤ 0.05 % Acidity, (as Acetic Acid) ≤ 0.1 % Colour on despatch /(Pt-Co) ≤ 10 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. Coatings, Inks, Adhesives: TBAc solvent finds use in decorative and industrial coating formulations, packaging inks and pressure-sensitive adhesives. It is a useful tool in the formulation of VOC-and HAP-compliant coatings, inks and adhesives. TBAc solvent is less volatile and flammable than exempt acetone and methyl acetate 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 generall....
