Why hydrographic dipping failure ?

By

Many people attempt to hydro dipping at home , but some problem always occurs . In this article , TSAUTOP will tell you why do you hydro dipping failure and give you relative solution at the following points .

1. Pattern with wrinkles

Pattern with wrinkles water transfer printing failure

If  your hydro dipping finished product  have been printed with your selected pattern , but there are wrinkles in the pattern . Because water transfer printing film don’t have enough dissolution time , you can solve this problem by delaying the dissolution time of hydro ink dipping film for better 3D water printing effect .

2.  The pattern is blurred

If there is a occasion which your water transfer printing products have blurred pattern , which express your hydro dipping paper  dissolution time is exceeded , please shorten dissolution time in the process of liquid ink hydrographics.

3. The pattern flows

The pattern will flow , if you spray activator excessively during the process of water ink transfer printing , reducing the amount of activator sprayed can solve the problem .

4. The pattern is not printed completely

hydro dipping failure pattern do not print competely

There are several reasons about incompletely painting : uneven activator spraying , high environment temperature or high water temperature ,  over fast evaporation of activator .

Spray activator evenly, lower the temperature of water , adjust a comfortable room temperature or prevent high wind coming into room to avoid activator evaporated .

5. Blisters on products’ surface

If you find there are blisters on finished products’ surface , then you activator does spraying  is not enough and product has a wrong angle to get into water to do water transfer ink printing . So please adjust activator does and change the direction and angle of product entering into water.

6. Poor adhesion of pattern after hydro dipping

If your material have oil on the surface or primer is wet , finished product will occur poor adhesion of pattern after water transfer inkjet . So please make sure material is cleaned thoroughly , primer is dry as well pay attention to whether you have done well about point 2 , 3 , 4 as above .

7. Material is blistering or cracking after topcoat is applied

Material is blistering or cracking after topcoat is applied

If there are blisters and crack on material’s surface after topcoat is applied , which express that the material have low solubility and the drying time is too short after primer is applied . You should choose other topcoat solvent to replace old one or delay the drying time of primer for better liquid ink hydrographics effect .

8. Poor adhesion of topcoat

If topcoat can not be bonded with material , maybe primer and topcoat do not match or topcoat does not match material . You should choose other paint to replace them .

9.  Topcoat painted yellow after drying

a. Drying time is too long and over high temperature also will cause this situation . If you lower the temperature and shorten the drying time , but this situation do not have any improvement , please replace this yellow paint .

b. Thick and uneven topcoat painting at the corner of product , will also cause topcoat painted yellow after drying . If you want to solve this problem , it is OK to reduce the amount of topcoat spraying .

These solution can help you solve above problems in hydro ink transfer . I wish this article can help you make a perfect hydro dipping products with your love water transfer film .

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 by 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.
