ARCOSOLV PTB is a colorless, combustible liquid with a characteristic odor similar to that of eucalyptus.
It is completely miscible with many organic solvents and has good solvency for a number of substances.
ARCOSOLV PTB and blends are substitutes for many ethylene glycol (E-series) ethers including butoxyethanol (EB).
It is soluble up to 18% in pure water at room temperature.
The solubility of ARCOSOLV PTB in water is increased by the addition of low molecular weight alcohols and other water miscible glycol ethers. |
