Chemical Composition
Monomethoxy polyethylene glycol
Advantages
- It is a clear neutral liquid at room temperature. It is soluble in water, polar organic solvents like acetone or methanol and is insoluble in pure hydrocarbons. Shows typical chemical reactions of alcohols/diols and a very low evaporation rate. With isocyanates and polyester they act as endcap and hydrophilic component. When reacted with unsaturated monomers like acrylic or methacrylic acid esters are formed which can be copolymerized in order to increase hydrophilicity and improves dispersing properties of polymers in water.
Other Applications
Polyglykol® M 750 PU is especially suitable for reactions with isocyanates.
