ARGUNA® ET-P Bright Silver Electrolyte

ARGUNA® ET-P Bright Silver Electrolyte

Bright silver electrolyte for technical applications

The ARGUNA® ET-P silver electrolyte is used to deposit bright silver coatings for (electro) technical applications. The process is especially suitable for rack operation.

Deposits on matt surfaces are smooth and fine-grained. The coatings have very good electrical properties. The hardness of the coatings as plated is about 110 - 130 HV 0.025 and drops to a final value of 70 - 80 HV 0.025 during storage.

ARGUNA® ET-P is a fine silver electrolyte of ultra-bright coatings with excellent bonding, soldering and adhesive properties. It is mainly used for LED application with full plated silver leadframe.
