GOLPANOL PME
CAS: 3973-18-0
Chemical nature: Propargyl alcohol ethoxylate
Molecular formula: C5H8O2
Molar mass: 100.12 g/mol
IUPAC Name: 2-prop-2-ynoxyethanol
The Golpanol product line is a collection of high-quality basic & top brighteners to aid final product finish in a variety of metal working and metal finishing applications such as electroplating, nickel baths, etc.
GOLPANOL PME is a superior rinse aid for nickel.
Key Value Props:
-Lower vapor pressure
-Easier to maintain concentration in bathless volatile than PA
USES:
-Formulate brighteners for electroplating
-Top brightener in nickel baths
PROPERTIES:
Physical form: Clear, colourless or yellowish liquid
Water content: max. 0.5 %
pH: 4.0 – 7.5
Refractive index: 1.449 –1.453
APHA colour: max. 50
Density: 1.02 –1.04 g/cm3
Solubility: Golpanol PME is soluble in water and in organic solvents such as methanol, ethanol and acetone.
Application
Golpanol PME is used to formulate brightener additives employed in the electroplating industry.
Golpanol PME is used as a top brightener in nickel electroplating baths at a concentration of 10 – 30 mg/l.
Golpanol PME is very effective in combination with other top brighteners and basic brighteners.
Because Golpanol PME is less volatile than Golpanol PA and has a lower vapour pressure, it is easier to maintain its concentration in the electroplating bath constant than if Golpanol PA is used.
Storage: Golpanol PME has to be protected from light, heat and ambient air.
Golpanol PME has a shelf life of one year in its sealed original packaging.
