Questions

  1. Can this be used to create a hydrophilic coating on an SLS 3D printed part? If so, how would that be done?

    1 answer

    1. The compound Poly(ethylene glycol) is hydrophilic. However, clarification is needed regarding the specific type of surface intended to be coated with a hydrophilic layer. Consulting relevant peer-reviewed literature is recommended for detailed methods and applications. Below are a couple of articles that may be beneficial, but further research will be necessary.
