The following products are suitable for application with Swarovski Ceralun Clay:
Ceralun is a versatile and strong two-component, high-performance ceramic epoxy composite. This clay has been specifically developed and tailored to embed foiled and unfoiled crystals. Ceralun has a high level of hardness, rigidity, and shock absorbance. It is resistant to sweat, humidity, or climatic changes, and shows no aging.
APPLICATION OF SWAROVSKI CERALUN CLAY
When working with Ceralun, optimal results are obtained by coordinating the entire application process. Following the application steps in the right order is very important. Experience has shown that the most common reasons for crystals becoming detached are inappropriate areas of application, the wrong mixing ratio of the two components, or not mixing them together long enough until a homogenous appearance is achieved.
Ceralun Two-Component Ceramic Epoxy Composite
Ceralun was especially developed for the application of both foiled and unfoiled Swarovski crystals, exclusively distributed by Swarovski for professional use within the jewellery segment and other industries such as accessories, interiors, and electronics.
Checking Surface Tension
The surface tension is an indicator for the wetting properties of the surface the Ceralun should be applied to. A surface tension of at least 38 mN/m is recommended for working with Ceralun. It should also be randomly tested during production. It is best to use the Test Pen (art. 9030/000) to measure the surface tension.
Note: On porous or absorbent materials, the surface tension cannot be checked with the Test Pen. If the Test Pen is used on highly polluted surfaces (e.g. grease, oil) or on material like wood, the Test Pen might be polluted as well and cannot be used anymore.
If the surface tension is below 38 mN/m, the following pre-treatment cleaning methods, applied in the correct order, can be effective in reaching the right level.
Mixing Ceralun Two-Component Ceramic Epoxy Composite.
The hardening time and final adhesion strength of Ceralun are dependent on the temperature. The total hardening time at room temperature of 23 °C (73.4 °F) takes 72 hours. This can be accelerated using heat of max. 80 °C (176 °F).
Setting of Crystals
After mixing the two components together, the crystals can be set. To prepare Chatons for the positioning process, a Chaton Sieve can be helpful. Take the black sieve (for size PP 0 – PP 1, art. 9030/003), the gray sieve (for size PP 2 – PP 20, art. 9030/001) or the blue sieve (for size PP 21 – SS 34, art. 9030/002) according to the Chatons’ size.
Place some Chatons onto the sieve. By slightly shaking the tool and wiping over the crystals with glove-covered fingers, the majority of Chatons automatically get turned into the suitable position for gluing (table pointing upwards). As a next step the Chatons can easily be picked up from the sieve using a tool like the wax stick, tweezers, or a vacuum pick-up system. The use of a silicone wax stick is not recommended as this can impair the adhesion and the brilliance of the crystals. Apply the Chatons to the desired position and press down gently.
We recommend a maximum working time of three hours at a temperature of 23 °C/73.4 °F to set the Swarovski® products. It is not possible to set crystals at room temperature after a period of three hours because the required level of adhesion can no longer be achieved. Please take care that the pavilion of the crystal is surrounded by Ceralun right up to the level of the stone’s girdle. It is not necessary to leave any particular space between the crystals when setting them.
Ceralun is the perfect material for generating a variety of surfaces and structures. Possible ways of processing are the free forming method, the stamping technique and the 3D silicone molds.
Generating shiny surfaces with the free forming method - When a piece of jewellery is created where parts of Ceralun are visible, a smooth and shiny clay surface might be desired. In order to create a shiny surface, gently wipe and polish the clay with your silicone glove-covered finger using the recommended Release Agent or some water drops. The Ceralun surface can be polished up to 2 hours after the crystals have been set.
Generating shiny surfaces with the stamping technique If a larger surface of shiny Ceralun is needed, the following is required:
3D silicone molds
The work and cost saving method of using 3D silicone molds is recommended for larger production units. A 3D silicone mold is produced based on a master model. This can be re-used for several times.
EXTENSION OF CERALUN LIFE
In order to get the maximum life out of the Ceralun Clay, follow these guidelines:
MIXING DIFFERENT COLOURS OF CERALUN
You can mix different colours together as you wish. Please consider that you have to separately mix the epoxy resin and hardener of each colour before you mix them together. Below you find some examples of mixed colours and the corresponding mixing ratio.
