Preparation of objects to be enamelled

Degrease carefully clean the pieces to be enamelled, check that there are no residues of fatty substances that decrease the adhesion of the enamel. Various types of degreasers can be used: alcohol, nitro thinner and degreasers.

If you do the last cleaning with ultrasonic washing machines, verify that there are no surfactants or brighteners in the water that release a coating on the piece to increase the brilliance but that they will form a surface film on which the coating with enamel will go. If so, the enamel will not adhere to the piece and failing to penetrate the microporosity of the piece will not have the desired adhesion.

STAGES OF PROCESSING

mix the product well
take a container (also made of plastic), put the enamel and the catalyst in proportion (for the catalysis see: catalysis of the enamel!) and mix well.
choose the size of the needle to be used and apply it to the syringe
pour the enamel and catalyst mixture, duly mixed, into the syringe
attach the syringe to the nail polish dispenser attachment
adjust the working pressure (see dosing instructions for enamel)
start the work by distributing the enamel in the chosen points
for the processing of the enamel to be sanded, it is advisable to bring, if the material allows, the piece to a temperature of about 40/70 C, to eliminate any air bubbles created during processing.
After the application, put the pieces in the oven at a maximum temperature of 80/90 ºC (if air bubbles have appeared it is advisable to flame the pieces before inserting them into the oven).

Note: For drying the product see specific section.

ENAMEL CATALYSIS: NH 203 or KZ 703 with catalysts E411 and/or NH 411/2172

CATALYSIS RATIO: 40 out of 100 (on the label you will find written: CATALYZE TO 40% WITH E 411 or NH 411/2172)

Note: Adhere precisely to the enamel-catalyst ratio by weight not in volume!

Example: 10 grams of enamel + 4 grams of catalyst.

Flat enamelling

For FLAT ENAMELLING, that is when you have to enamel surfaces that have a “seat” (socket) to accommodate the enamel, the catalyst E 411 should be used that makes the enamel liquid and self-leveling.

In this case it is recommended to heat the piece before decoration, for example by placing the piece on a heating plate or putting it first in the oven at a temperature of 40-60 ºC.

Doing so speeds up the application and limits the formation of possible air bubbles. As soon as the enamel touches the piece, it will automatically spread along the entire seat prepared for glazing.

Once the deposition of the enamel “flame the piece”, that is, quickly pass an oxidizing flame directly on the surface of the enamel placed on the object to eliminate any small bubbles present on the surface.

Round enamelling

For ROUND ENAMELLING (enamelling on three-dimensional objects) the catalyst NH 411/2172 TIXOTROPICO should be used, which makes a mixture of more viscous enamel-catalyst that will remain more firm in the position in which it will be placed.

Apply the hardened enamel on the workpiece by rapid circular movements to obtain the desired glazing and a smooth uniform surface.

Although being the most viscous product if you cover the three-dimensional piece completely the enamel would tend to pour by the force of gravity therefore it is necessary to dry it in rotation.

Note: It is possible to catalyze the enamel with a mixture of the two catalysts E411 + NH 411/2172 in different proportions while maintaining the right catalysis ratio.

Example 1: 10 g enamel + 2 g E411 floor catalyst + 2 g NH411/2172 thixotropic catalyst

Example 2: 10 g enamel + 3 g E411 floor catalyst + 1 g NH411/2172 thixotropic catalyst

etc.

Drying

ATTENTION: The workability of the enamel is about 45 minutes, therefore it is advisable to catalyze only the amount of product that will be used.

The curing of the enamel takes place at a temperature between 22 ºC and 90 ºC.

DRYING IN THE AIR

The pieces decorated with enamel can be dried in the air; if you want to air dry the piece colored with enamel, you need a condition of room temperature not lower than 22 ºC and a humidity rate not too high (it is sufficient to comply with the climatic and environmental conditions necessary for the normal performance of the work activities planned for the staff).

If you choose such a drying procedure you have sufficient polymerization after about 24 hours. However, the resistance of the color to the scratch will increase over the days until it becomes maximum after about 72 hours.

DRYING IN THE OVEN

To accelerate the curing process you can get the drying of the product painted with enamel, putting it in the oven respecting the following table time – temperature:

240 min at 50 ºC

200 min to 70 ºC

120/180 min to 80/90 season C

The temperatures correspond to the temperature of the object; it is therefore advisable to check for each individual case the temperature to obtain an adequate polymerization.

Once you have obtained the complete polymerization of the decoration made with enamel, you can proceed with any subsequent processing:

application of transfer sheets for the creation of textures and patterns.
sanding and polishing (after at least 24h)
