ABOUT US 

Who we are 

IWG is a family-run company in the third generation and stands for continuity, premium quality and flexibility. 

What we do 

IWG has been involved in the development of plating chemicals for almost 50 years. The product portfolio ranges from 

pretreatments, plating bathes to posttreatments with focus on precious metal plating especially designed for costume jewelry, 

goldsmiths and optical frame industry. 

Our experience combined with the strong intention of development and improvement of processes enables us to a global

ULTRASONIC CLEANING 

IWG offers special designed Ultrasonic Cleaning solutions. Ultrasonic 

Cleaning is important to dissolve and suspend contaminants. While 

metal surfaces are inhibited to protect the parts from etching, oils and 

greases are saponified and metal ions are complexed. 

TYPES 

• 22400 US CLEANER make up 20 g/l 

Appearance: solid 

• 22420 UNICLEAN 70 make up 20-50 ml/l 

Appearance: viscous solution

DEGREASING 

The degreasing process is important for an optimal preparation 

of the parts before electroplating. 

IWG recommends “Degreasing 1018” - especially for fine 

jewelry and costume jewelry. 

TYPES 

• 22115 DEGREASING 1018 part 1 salt 

• 22116 DEGREASING 1018 part 2 solution 

• 22117 DEGREASING 1018 M part 2 solution

PLATING 

PLATINUM 

PROPERTIES 

Platinum is a metal with a beautiful silvery-white surface. It is exceptional 

because of its ductility. Platinum is resistant against wear and tarnishing and 

therefore particularly suitable for fine jewelry. 

CHARACTERISTICS OF THE BATH 

• white bright surface 

• easy handling in terms of plating bathes 

• the electrolytes have an excellent throwing power so an even 

thickness can be reached over a wide range of current densities 

which leads to a reduction of costs 

• the electrolyte has an outstanding fast covering force to protect the base 

material from etching 

• replenishable 

• Vickers hardness 350-500 

Pt

• 35551 PLATINUM make up solution make up 100 ml/l 

• 35555 PLATINUM replenisher 

• 35560 PLATINUM GAM part A 

• 35561 PLATINUM GAM part B 

make up 80 ml/l part A + 40 ml/l part B

RHODIUM 

PROPERTIES 

Rhodium is a silver-white metallic element, which is highly resistant against 

corrosion and highly brilliant. 

It is an extremely rare precious metal and one of the most expensive in its 

range. 

Because of its extraordinary high brilliance rhodium is applied for top coating 

of various pieces of jewelry. 

Rhodium is also used as corrosion protection for silver. In general, rhodium is 

darker than silver. Therefore rhodium has to be as white as possible to look 

as similar as silver. IWG rhodium solutions are incomparable in colour and 

brightness. 

IWG offers a wide range of different plating solutions. 


• highly brilliant, bright and white coating 


• good throwing power 

• high hardness 

• high corrosion resistance 

• replenishable by rhodium replenishment concentrate

PALLADIUM 

PROPERTIES 

Palladium is a silvery, bright, lustrous and ductile metal, slightly harder than 

Platinum. 

The Vickers hardness of palladium as a galvanic coat is HV 230 – 250. 

Expanding its crystal lattice, palladium is capable of absorbing hydrogen at a 

rate of 350 - 380 times of its own volume, in colloidal solution even up to approx. 

3000 times of its volume (at normal temperature). Thin palladium sheets 

are permeable to H2, but they will swell notably, becoming brittle. Therefore, the 

electroplating process must suppress this property of palladium. 

Palladium is used as a corrosion protection or diffusion barrier as a substitute 

for nickel. It is very often used as layer underneath rhodium. Palladiums abrasion 

resistance is exceptional. 


• white colour 

• exceptional corrosion resistance 

• neutral pH

Pd Gapal FS Pd Gapal HT 

TYPES 

• PALLADIUM GAPAL FS 

The pure palladium process Gapal FS is a weak alkaline electrolyte from which 

bright decorative white pure palladium layers can be deposited. Layers of Gapal 

FS can be used up to about 0,5 µ as a diffusion barrier or as a flash palladium 

in the bijou and optical frame production. 

CHARACTERISTICS 

• easy to control 

• Palladium content of the electrolyte is only 2 g/l 

• pure palladium can be deposited, no alloying metals as brighteners 

• substitute for nickel as diffusion barrier 

• Palladium is not sensitising 

• PALLADIUM GAPAL HT 

The pure palladium process Gapal HT is a weak alkaline electrolyte from which 

bright, decorative white-levelled pure palladium layers can be deposited. Gapal 

HT has been formulated to get crack free and non-porous layers. Gapal HT 

enables deposits of thicknesses above 5 microns with mirror bright finish that 

is the reason why it can be used as an excellent corrosion protective nickel 

substitute. 


• very white layers can be deposited 

• layers are free of cracks 

• bright deposits up to 5 µ are possible 

• pure palladium can be deposited, no alloying metals as brighteners 

• substitute for nickel as diffusion barrier 

• Palladium is not sensitising

SILVER 

PROPERTIES 

Pure silver has a brilliant white metallic glance. The metal is a little harder than 

gold and very ductile and malleable. Pure silver has the highest electrical and 

thermal conductivity of all metals, and possesses the lowest contact resistance. 

Silver is stable in pure air and water, but tarnishes when exposed to ozone, 

hydrogen sulphide, or air containing sulphur. 

Silver plating is one of the oldest applications of galvano technique. The first 

patents of these applications were noted in 1838 and 1840.

GOLD 

PROPERTIES 

Gold is a yellow, brilliant, highly malleable and extremely durable precious metal. 

Gold and copper are the only coloured metals. 

Naturally, the colour is an important characteristic of a gold layer. 

Various gold colours are required for decorative applications, which are created 

by employing alloy partners with a sometimes considerable weight percentage. 

Care must be taken that the corrosion resistance and colour consistency are 

compromised. 

IWG has developed a special system of baths for fine jewelry: 


• deposits with constant colour 

• hard gold coating 

• thickness of the deposit up to 0,2 µ 


• good macrothrowing power of the electrolyte 

• high fineness (more than 18 carats)

RUTHENIUM 

PROPERTIES 

Ruthenium is a hard, white metal. It does not tarnish at room temperatures, but 

oxidizes in air at about 800°C. 

Ruthenium is a metal, which is mainly used for top coating. It is very hard and 

can be plated in various shades of anthracite to dark grey. If gold is plated underneath 

antique effects or bicolour effects can be reached. 


• light grey to nearly black colour 

• bright deposit
