M-type polyglycols are used for a wide variety of chemical reactions.
With isocyanates and polyester they act as endcapping and hydrophilic component.
When reacted with unsaturated monomers like acrylic or methacrylic acid esters are formed which can be copolymerisized in order to increase hydrophilicity and improve dispersing properties of polymers in water.
Storage of Polyglykol M 400:
When Polyglykol M 400 stored in a cold, dry place in a closed container Polyglykol M 400 can be kept for at least two years.
