How To Hydro Dipping: The Complete Transfer Printing Process

Hydro Dipping Process

Hydro Dipping Step 1: The Surface Cleaning for Base Coating

What you need to prepare for base coating are grease and hydro dipping dip-kit. Before base coating, you need to make sure that the item is very clean which is made up of grime and water. Hydro dipping dip kit comes with a Scotch pad and a piece of either wet or dry sandpaper with 800 grits on which can be used to lightly scuff the part you are dipping so that the primer can be bonded with the part. This is essential.

Also , don’t forget to wear latex gloves to clean the part , which could avoid any grease from your hands dipping on the base . In this process , you are not allowed to touch items to be printed . This is to prevent any grease from getting onto the item from your fingers , which affects the result of the painting reaction .

In order to wipe the item thoroughly without any remaining dust/debris prior to priming , the tack cloth is highly required instead of the regular wiper . This will leave your item very clean and be ready for the next step in the hydro dipping process .

Hydro Dipping Step 2: Priming and Base coating

The primer should be ready to apply after all prepares . We provide all kinds of primers , including white , black and other colors . Shake the can vigorously for 2-3 minutes before applying a light dust coat . Next, Wait for 10 minutes and then apply a slightly heavier coat . Wait another 10 minutes , and then apply what should be your final coat . Do it gently to avoid the reaction as the solvent evaporates meeting painted item .

If the item still isn’t evenly covered , then continually add coats until it is evenly covered . Then , Wait for one hour for the part to be fully dry before moving on to the next step . Onto the next step in the hydro dipping project , Any primers can be removed completely with dry sandpaper which is in hydro dipping kit .

The next step in the hydro dipping process is applying the appropriate base coat . supply the color we recommend to your film if there is one . If the film has transparent parts in , you will be supplied with the paint color you have chosen . The paint we provide in the aerosol cans is automotive base coat paint . This is high-quality paint , which works well with the primer and films, performs well out of the aerosol can .

Hydro Dipping Step 3: The First Drying for Hydro Dipping

In order to avoid applying too much once , you should begin with small coats . Ten-minute drying after the coating is required . Dry the coat for 10minute (60℃-200℃, the temperature setting depends on the material) in drying oven or tunnel till its at least 80% dried before moving into the next step of the hydro dipping process .

Hydro Dipping Step4: Dipping

This is without a doubt that our favorite part of the hydro dipping process. Before hydro dipping , you need to start the heater of your hydro dipping tank for 30-90minutes and check the water temperature controller. You should prepare your items and cut the suitable size hydro graphics film when the water temperature is up to 25-30℃.

The item is now nearly ready to be hydro dipped in your hydro dipping film pattern. Use the masking tape provided “back tape” to the edge of your item. Leave the tape overlapping over the edge of the item . This helps that when the film breaks away during dipping , it will break on the tape. Which means that any problem occurs on the tape , but not the edge of your item.

If there are any areas with water rushing through where hydro dipping applied in , tapes should be applied to these films as well. This stops the hydro dipping pattern being pulled and distorted when water rushes through these areas.

after water warmed to 25-30℃ , lay the hydrographic films without bubbles of air and water between the film and the water trapped on the water. The film will be spread out and fill the surface area of the water after you apply the hydro dip activator. So use a tub that is approximately 10-15mm slightly bigger than the piece of film you are using.

Pinch the film‘s corner with wet your finger and thumb. The side that adheres to your finger is the water-soluble side and this side should face down in the water. Leave the film on the surface of the water for 45-60 seconds (the time depends on the film) before applying the activator.

Shake the activator spray can and slowly pass it over the film. Dip your item through the hydro dipping pattern with 45 degrees , when the film looks very glossy and acts like liquid on the surface of the water.

You can adjust the dipping angle (regular angle is 45 degree).

Hydro Dipping Step5: Rinsing or washing

After hydro dipping , you take your item out and rinse with clean water for five minutes in your hydrographic rinse tank until the residual PVA being washed away and the item is no longer slimy to touch as well.

Hydro Dipping Step6: Drying For Removing The Water

After rinsing , you can put the items into the drying oven or drying tunnel for removing the water about 20-30minutes. Certainly , you can put them outside if sunshine is sufficient.

Hydro Dipping Step7: Top Coating

After rinsing your hydro dipped item and leaving air to dry , you can apply the top coating. Again , shake the aerosol can be provided vigorously for 2-3 minutes. It is very important to apply very small dust coats of lacquer over the print , to begin with.

Applying a wet coat immediately can cause the lacquer reacting with the print , and make it distort. Apply a very light dust coat and leave to dry for 15 minutes.

Then apply another light coat and leave it to dry for 15 minutes. After this whole process , you can start building up heavier coats applying to a final wet whatever is in smooth gloss , satin or matte type.

Each merchant has hundreds of pre-designed patterns, but you can also choose to custom design the pattern you want, so what do you need to do when you need to custom design your unique pattern?

a. Prepare all the tools needed for custom hydro dip film printing

PVA blank film, inkjet printer, activator A, these tools are necessary if you want to design a customized water transfer printing film yourself.

b. Design the pattern and size you want

Design the corresponding size according to the size you want. For example: if you want the size to be 1m*1m, the set pattern size should also be 1m*1m. If the picture size does not reach 1m*1m, you can stitch the pictures.

c. Print the designed hydro dip film

After designing the pattern, it is recommended that you test it first by printing a small part to see if the printed color is what you want. If it is not suitable, you can replace the ink or adjust the printer in time.

d. Apply activator A

Activator A is used to protect the ink and successfully transfer the pattern to the item during the hydro-dipping process. In addition, after applying activator A, you must wait for it to dry before rolling it up, otherwise the ink will fall off and be damaged. This is very important, otherwise it will affect the result of flooding.

3. What factors should be considered when designing custom patterns?

a. Pattern color and transparency selection

When designing patterns, attention should be paid to color matching and the color of the surface of the object itself. Some designed patterns have high transparency, and the color of the object itself is still visible under the pattern. Therefore, the impact of transparency on pattern overlay will affect the final pattern display.

b. Pattern details

The pattern needs to be clear enough, especially if the pattern is complex, to prevent the effect from being poor after being soaked in water.

c. Design format and software

It is recommended to use professional design software and high-resolution files. Professional design software can ensure high-quality output of patterns; high-resolution files are suitable for water transfer printing requirements.

4. Conclusion

Water transfer printing is a very simple technology. It can not only achieve the pattern design you want but also turn items into works of art. I hope this article can help you understand how to make a custom hydro dip membrane. If you have any related questions, you can contact us at any time.
