Liquid Bright Palladium Heraeus GP 350 H - Precious metal products for the decoration of ceramics

Liquid bright palladium suitable for IR / heat reflective layers, RoHS compliant

Palladium for Pottery is a liquid metallo organic palladium solution for usage on glazed ceramic substrates and quartz glass. It is mostly on IR/heat reflective lamps and typically applied by spraying. The firing result depends on the firing temperature, the soak time and the total cycle of the firing as well as on the type of substrate. For an optimal firing result, we recommend pre-tests under the user's own individual conditions.

Processing

We deliver the Heraeus GP 350 H Palladium preparation ready to use. Do not shake the material before usage. The material might have built a minor settlement, especially after a longer period of storage, which should not be shaken up. Had the material been stored in a fridge, please give it a bit of time to adjust to the room temperature before starting to use it.

Application by airbrush / electrostatic spray: In case of spraying, please thin down the material with V16 by 25 to 35% by weight.

A possible thinner in case of a brush application is V35. Level at room temperature for about 5 minutes. Dry at room temperature for a further 60 minutes.

Storage

Liquid Palladium is subject to an aging process. Therefore, we recommend using the material within 9 months. The material should be stored at room temperature (20°C). Cool storage – but no freezing – has a positive impact on the shelf life.

Consumption

The material consumption depends on the thickness of the applied precious metal layer. Under our conditions, the consumption is approx. 0,15 to 0,30g/100 cm².

Compliance to regulation

The properties of the product are determined following standardized laboratory test procedures. For optimal results, the material should be fired in a profiled furnace supplied with dried, hydrocarbon, and other contaminant-free air.

REACH (SVHC)

The material is REACH (SVHC) compliant according to the latest ** Annex XIV to Regulation (EC) of the European Parliament and the council on the Registration, Evaluation, Authorisation and Restriction of Chemicals (“REACH”) by European Chemicals Agency and its subsequent amendments; the material does not contain any substance listed in Annex XIV.

RoHS

The material is RoHS compliant according to the latest ** Directives (European Union) of Restriction of Hazardous Substances (“RoHS”) and its subsequent amendments (including the exceptions related to Pb)

Application of the material 

- Preparation of the substrate to be decorated Make sure that the surface of the object to be decorated is clean and dry. Dust, fingerprints, and water condensation can affect the decoration while firing. Take care that the object to be decorated is not taken from a cold store into a warm shop. A fine condensation film may occur, which is not visible to the naked eye. Result: Firing disturbance (pinholes) in the fired precious metal decoration! Allow enough time for the substrate to adjust to the decoration room temperature. 

- Firing Precious Metals During the first heating phase the organic components of the preparation burn off. This process is completed at approx. 400°C. The palladium film is formed. A constant, slow temperature increase, enough oxygen, and sufficient ventilation are decisive for the quality of the fired precious metal decoration. The firing profile considerably influences the mechanical and chemical properties of the fired decoration. The rate of cooling has no major influence on the quality of the gold decoration, unlike the firing temperature and soak time. However, the firing process should not be stopped too abruptly after the soak time. If the rate of cooling is too fast, there may be a danger of damaging the article (cracks and broken glass).
