Perfect coating and improved appearance

insulbar with ESPOC

Ensinger has developed ESPOC, a solution that can be applied to insulbar profiles. ESPOC is a thin layer that is applied to both our standard profiles and customised profile designs using an innovative process. The result is an almost perfect powder coating of the profiles in our customers' systems - the ESPOC effect.

You can have insulbar RE and insulbar REG profiles coated with ESPOC. Would you like to find out more?
Our ESPOC team will be happy to advise you.

The ESPOC Effect

Regardless of the moisture content of the profiles treated with ESPOC, the attraction of the powder remains at a constantly high level during the coating process. An optimum coating result can be achieved even with dry profiles and the  "blistering effect" (formation of bubbles in the coating process) can be eliminated. ESPOC can be applied on various profile contours at the desired surface, including protrusions and undercuts.

Without ESPOC coating

With ESPOC effect



  • High-quality appearance in the profile system 
  • Perfect coating result possible


  • Applicable to existing or new standard and customised profiles
  • Can be applied to many insulbar materials
  • Available as an option

Process improvement

  • Safer and improved powder coating process
  • Lower reject rate 
  • Improved paint adhesion
  • High attraction in the powder coating process in assembled or solitary profiles

Further advantages

  • New and greater degrees of freedom in the design of visible insulating profiles
  • Unchanged thermal conductivity of the base profile
  • Consistent mechanical properties


The surface is made electrically conductive using an innovative process. The electrostatically charged powder particles are attracted to the earthed surface of the insulating profile in a similar way to the attraction of conductive metals. This means that both aluminium-plastic assembled profiles and solitary PA profiles can be optimally coated, resulting in an outstanding appearance in both cases.
