Provides an overview of DURASURF (moisture-resistant insulating coating)



DURASURFDURASURF<Fluorinated coatings>

Moisture-resistant insulating coating

DURASURF coatings can be used to prevent metal migration on circuit boards, to prevent ion migration (metal ions migrating from one electrode to another), to make circuit boards in outdoor devices moisture-resistant, to make circuit boards in industrial equipment moisture-resistant, and to prevent metal from rusting.

Prevents metal migration on circuit boards
Product name Sample Application
DS-3200 Mobile devices (mobile phones, smartphones, etc.)
Touch screen sensors (silver wiring, crimped contacts on flexible printed circuits)
Lithium ion battery packs LED backlighting for LCDs, LED lighting
The heating cycle that is used to produce a moisture-resistant coating primarily for circuit boards results in stress compliance. This leads to a relatively soft coating (4B on a pencil hardness test)
