ALKOX EP-N series is low molecular weight random copolymer of ethylene oxide and propylene oxide.
ALKOX EP1010N has similar molecular weight and viscosity of aqueous solution to ethylene oxide homopolymer grade of ALKOX L-11.
ALKOX EP1010N is relatively-low molecular weight, so it is easy to handle and able to make a solution at high concentration.
By copolymerizing with propylene oxide, it shows more compatibility with other resins and organic solvents and improves the solubility to organic solvents.
In addition, it has flexible and adhesive property with low crystallinity and transparency.
By using these properties, ALKOX EP series are expect to utilize in the application of resin kneading, film forming and as a binder.
