Gold Plating Services’ 24k Pure Pen Gold Solution is an extremely efficient, (cathode efficiency 90%+ ), neutral pH, water clear gold plating solution designed to produce a gold electro-deposit of 99.9+% purity to virtually any desired thickness for surfaces used in the medical, semi-conductor, electronic, and PWB industries where soft, high purity gold is required. Due to the grain structure of this type of gold deposit the reflective qualities of the surface will become noticeably “matt” with increased thickness.

Electrodeposited gold will be equivalent to Type III, Grade A, specifications as indicated in MIL-DTL- 45204D, as follows;

Gold Content -      0.7g fine gold content/15ml
Purity -                  99.9+ percent gold minimum (24 karat)
Hardness              Knoop hardness < 90 (typically 55-60)
