Improve Precision and Reduce Time When Removing Conformal Coatings

Posted by Vlad David on May 21, 2018 11:00:00 AM

UV curable conformal coating materials such as HumiSeal UV40 are frequently used in military, aerospace and automotive applications due to superior resistance to chemicals and mechanical stress. These properties make them difficult to remove when rework under the coating is required.

There are products available for chemical removal of conformal coatings, but many are restricted by government regulation and health and safety concerns.

An effective method for localised removal of conformal coatings, allowing the rework of the components, is the powder or micro-abrasion equipment.

3 Simple Ways to Remove HumiSeal UV Conformal Coatings

Posted by Matt Eveline on Aug 15, 2017 11:00:00 AM

This blog post outlines the techniques required for the removal of HumiSeal UV cure conformal coating. The products covered in this article are:

  • UV40, UV40-250
  • UV50LV
  • UV500, UV500LV

There are 3 methods for the removal of HumiSeal UV conformal coatings:

  1. Mechanical removal: Powder Micro Abrasion
  2. Thermal removal: Burn Through
  3. Chemical removal

All three methods will effectively remove the coating, depending on the process requirements, to allow individual component replacement and subsequent re-coating.
