PVC Plastisol Coating What is it?
PVC Plastisol coating is a type of coating usually used for the protection of metal surfaces or for decorative purposes. This coating is a polyvinyl chloride (PVC) based material that is often used in various industrial applications.
Reasons why plastisol is especially preferred for use on metal surfaces;
PLASTICYOL APPLICATIONS
The use of PVC plastisol in applications such as coating, molding, immersion and casting has increased dramatically because it is cost-effective; plastisol formulations can be varied to achieve the desired end results.
Parts to be coated must be chemically cleaned before coating. This is an important step to remove grease and dirt from the part.
PVC plastisol has acceptable adhesion to metal, but if more adhesion is desired, the metal should be primed. The primer can be applied by spraying, spraying or dipping. The cleaned metal surface is primed and dried, then heated to 180-200ºC. This step is necessary in case of changing the polymer system of the primer and hot dipping.
Dip Coating
Hot dip coating is by far one of the most common plastisol processing techniques. Hand tools, children's play groups, outdoor furniture, ball valve handles are coated with dip coating. The part to be coated is dipped in plastisol and cured, this process is called dip coating. Adhesive primer may be required for the metal surface.
The primed and heated metal surface is dipped into the plasticizer. The immersion speed should be slow and uniform to avoid different film thicknesses and dripping. A thickness of up to 10 mm can be achieved in plastisol coating. The coating thickness depends on the mass of the part, the preheating temperature and the time the hot part remains in the immersion tank. The higher the temperature of the metal and/or the immersion time, the greater the thickness of the coating. Usually parts are dipped vertically, the dipping angle should be chosen to prevent dripping and air bubbles.
Then the curing process is necessary. When the curing step is completed, the part is plastisol coated.
We can explain the dip coating application with a very simple visual as follows. In dip coating applications, the dimensions of the pool to be immersed may also vary according to the material to be coated with plastisol.
Dip Coating, also known as dip coating, dip plating or metal surface coating, is among the benefits of the coating process;
- Resistance to peeling, cracking and chemicals,
- Long lasting color and gloss on the surface,
- In hardware products such as small hand tools, etc., the products look decorative and their grip is more ergonomic,
- Improving protection performance in environmental factors that require long term durability,
- Especially in metal surface coatings and in the coating of children's playgrounds, sharp parts are completely eliminated or minimized.
Cold dip coating does not require preheating of the metal part. The amount of plastisol taken up by the part is usually based on the plastisol ratio and viscosity. In the case of cold dip coating, the curing step is always necessary.
As Delta Kimya, we provide production in all main colors with our registered trademark PLASTO® in dip coating applications made with plastisol. Please contact our R&D department for different colors and shore (hardness) applications with smooth and texture surface options that can be customized for you.
Immersion Molding
It is the process of heating the mold and immersing it in plastisol. After the plastisol is cured, it is removed from the mold. Examples of this application are gloves, caps, handles and grips, anti-vibration parts.
