Bright Precious Metal Preparations for the Production of Decals for Porcelain and Bone China

 
1   General Information
We supply bright noble metal preparations for manufacturing decals for porcelain and bone china with various precious metal contents. Depending on the precious metal content and the deposit of the precious metal application, the precious metal film layer thickness is 0.2-0.3 μm after firing.
 
2   Standard Firing Range:
 

Substrate type Firing range
Porcelain 760℃~ 850℃
Bone China 760℃~ 830℃
 
 
In order to achieve a maximum result, the optimal firing temperature range we recommend is 760 to 820°C.The firing result depends on the firing temperature, on the total firing time and the soak time and also on the properties of the glaze.Our products should be tested individually by every customer using his application and firing conditions.
 
3   Storage:
The paste viscosity raises during the storage time（when customer re-uses the collected paste, customer can add a proper amount of thinner according to flowability of the paste）. Therefore, generally speaking, the recommended storage time is within 12 months at room temperature (（20℃）. Gold paste is supposed to be placed at 6℃～10℃in a refrigerator if its opened, which can extend their quality life.
 
4   Processing:
Thinner must be added into our preparations to adjust its viscosity before printing. The optimum adding proportion of the thinner will be recommended. Before printing, we are supposed to fully mix the thinner into the preparation first, seal them well, and then place them there for one to two hours.
The paste viscosity raises during the storage time, which will affect its printability. In this case, we recommend adding approx. 5% thinner to adjust viscosity before re-using.
Upon request we can submit to you complete application information
 
5   Consumption：The material consumption depends on the printing parameters as screen fabric, stencil, coating, squeegee position, squeegee pressure and slop. Experienced values for the consumption are 0.16~0.3/100 c㎡
 
6   Properties Of Finished Decorations
The main properties of fired bright precious metal decorations comprise brilliance and precious metal tone, as well as resistance to mechanical and chemical attack. Nevertheless the quality of a fired decoration depends on preparation, application, substrate surface and firing conditions.
 
7   Product: 
Bright Gold &Platinum Preparations
Color shade: light yellow (lemon), reddish yellow, platinum
 
8   Frequent Faults, Their Causes & Ways Of Avoiding Them
 
Fault Possible Cause Remedy
stripes in the printed precious
metal decoration		 the squeegee shows possibly
scratches		 squeegee exchange, or grind off
the old one
blurred contours, running precious
metal		 too much thinning of the product (The paste is too liquid) limit the addition of thinner, orleave the pot open for a while, so that some of the solvent can evaporate,or add paste with high viscosity to neutralize it
spots and matt firing result contamination as dust, finger
marks or water drops		 clean the object before decorating
Problems in the kiln such as
●　Reduced atmosphere in kiln
●　insufficient ventilation
●　heat increase is too fast during　critical phase　between300~400℃
●　too many pieces in the kiln		  
●　increase air addition
●　improve ventilation
●　reduce the heating speed
 
●　reduce the number of pieces
in the kiln
precious metal cracks during
firing		 contamination of the substrate
surface causes cracking		 clean the substrate before
application of decal
the layer of the product is too
thick		 reduce the layer of the product
the layers surface doesnt dry enough print covercoat after it dries completely
low temperature warm pieces in hot water before applying decal in winter
cracking of the decoration decal extension was too huge do not extend the decal so much.
If necessary, use an elastic screen printing covercoat
steeping water is too cold and / or transfer of the decal onto a cold steeping water should be warmed
up a little
low mechanical resistance (bad adhesion) firing temperature is too low increase firing temp.
layer of the product is too thin adjust used mesh or height of screen
the productis too liquid reduce addition of the thinner
pinholes take objects from a cool store into a worm shop gives invisible condensation on the surface. Note this cannot be wiped off. It reforms
immediately.		 allow enough time for the ware to
reach shop temperature
bubble the productis too liquid reduce addition of the thinner
