Product Description

Product Description

TPNB glycol ether is a very slow-evaporating, hydrophobic glycol ether with outstanding surface tension-lowering ability; ideal where high polymer solvency and residence time are required. 

TPNB is the slowest-evaporating member of the family of  glycol ethers. 

TPNB is a high boiling, colorless solvent with low viscosity and practically no odor.

Due to its length and hydrophobic structure,  TPNB has a high organic solubility, low water solubility, and a high boiling point.
