Tpnb/ Tripropylene Glycol Normal Butyl Ether CAS: 55934-93-5

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.

Tulaga lelei

E tele a matou fale gaosi oloa maualuga ma le galulue faʻatasi, lea e mafai ona tuʻuina atu ia te oe oloa maualuga ma tau faʻatauvaʻa. Ma e mafai foi ona matou tuʻuina atu faʻaitiitiga mo faʻatauga tele.Ma matou te galulue faʻatasi ma le tele o kamupani faʻapolofesa felauaiga uta, e mafai ona tuʻuina atu oloa ma le saogalemu ma le sologa lelei i ou lima. Le taimi tu'uina atu e tusa ma le 3-20 aso talu ona fa'amaonia le totogiina.
