What are the Benefits of Membrane Coating?

What is a Membrane Coating?

A membrane is a barrier that is selective, allowing some things to pass while preventing others from proceeding. Typically used for preventing or allowing passage of molecules, ions, or other particles. Too function properly a membrane must not clog and ideally has surface properties which assist in allowing the desired materials to pass. A membrane coating can be a variety of treatments that optimize this behavior. Ideally these coatings are ultra thin or nanoscale so as not to clog the membrane. Membranes can benefit from a variety of treatment types. Hydrophobic coatings can assist with allowing oil and other organic material to pass. Hydrophilic coatings can assist with allowing water and other aqueous materials to pass alternatively.

What Applications Benefit from a Membrane Coating?

There are numerous applications in a wide variety of industries which can benefit from a membrane coating. Examples include medical applications, industrial, & consumer applications. Medical membranes treated to have optimized performance will have greater longevity and less propensity for clogging. Numerous industrial and consumer applications can also benefit from having optimized performance. You may benefit from a membrane coating if any of the following apply to your application:

  • Functional issue due to liquid behavior on surface
  • Speed of material through membrane is slow
  • Membrane is clogging
  • Surface energy is too high
  • Wettability of surface is not ideal

How are Membrane Coatings Applied? 

There are a wide range of options for application of membrane coatings. Examples include:

  • Selective Deposition Membrane Coating

For membrane applications requiring functionalization of only certain areas manual or automated selective spray/deposition can be utilized. A wide variety of application and nozzle options can support nearly any application and hydrophobic fluid regardless of viscosity. 

  • Dip Applied Membrane Coating

Dip coating can be utilized to treat large batches of membranes/parts which require complete treatment of all surfaces. Dip coating can be done manually or via automated process which controls insertion and extraction rates. Upside to dip coating is it is a simple process and allows for large volumes of quickly treated parts. Downside to dip coating is the need to properly maintain the bath concentration, mitigate evaporation & dragout losses, in addition to replacement of contaminated bath materials.

  • Membrane Coatings – Spray Application

Spray application is an effective and easy to implement coating process for application of membrane coatings to large surfaces or for high volumes of parts. Spray can be done via a manual or automated process and parts can be treated in line or via batch treatment.
