2K/3K Mixer and Auto Color Change System - Electrostatic Spary Coating

Electrostatic spray coating has become increasingly popular in various industries due to its efficiency and high-quality results. However, the need to mix and change colors quickly and efficiently has always been a challenge for painters. Traditionally, this was done manually, which was time-consuming and resulted in a significant amount of waste. The 2K/3K mixer and auto color change system is designed to address these challenges and provide a more efficient and cost-effective solution.


The 2K-3K Electronic Mixing & Dosing System typically comprises of the following components:

  1. Metering Pumps: These pumps are used to accurately control the flow rate of each component, ensuring that the correct proportion is mixed and sprayed.
  2. Mixing Chamber: The mixing chamber is where the two or three liquid components are combined and mixed together.
  3. Control Unit: The control unit is the heart of the system and is responsible for monitoring and adjusting the flow rate of each component. It may use electronic sensors, computer control and software to manage the mixing and dosing process.
  4. Display Unit: A display unit is used to show the operator the current status of the system, including the flow rate of each component, total amount of liquid mixed and any alarms or faults that may arise.

The system may also be equipped with additional features such as automatic cleaning, continuous monitoring, and alarms for low level and low pressure, to ensure the reliable and consistent operation of the mixing and dosing process.

Overall, the 2K-3K Electronic Mixing & Dosing System provides precise control over the mixing and dosing of two or three liquid components, which results in a more efficient, consistent and uniform application of the sprayed liquid.

2-component (2K) paint systems

2K paint hardener is a curing agent that is used in 2-component (2K) paint systems to increase the curing speed and hardness of the paint. It is typically composed of polyisocyanates, which react with the paint’s polyol component to form a cross-linked polymer network. This network provides the paint film with its hardness, adhesion and chemical resistance properties.

When using 2K paint hardener, it is important to use the correct mixing equipment to ensure proper dispersion and mixing of the hardener into the paint. A high-shear mixer, such as a rotor-stator or a planetary mixer, is typically used for this purpose. These types of mixers create a high level of mechanical shearing that helps to break down any lumps or clumps in the hardener, and also promotes better dispersion of the hardener particles throughout the paint.

In addition to the mixer, it is also important to use proper measuring equipment, such as a graduated cylinder or a digital scale, to measure out the correct amount of hardener according to the manufacturer’s instructions. This is crucial to ensure the proper mixing ratio and to achieve the desired curing and hardness properties in the final paint film.

It is also important to use appropriate safety equipment, including gloves and a respirator, when handling 2K paint hardener, as it can release harmful vapor when exposed to high temperatures and humidity.

In summary, 2K paint hardener is an essential component in 2-component paint systems, and it is important to use the correct mixing and measuring equipment, as well as appropriate safety equipment, to ensure proper mixing, dispersion, and safe handling of the hardener.

3-component (3K) paint systems

3K paint refers to a 3-component (3K) paint system, which typically includes a base paint, a hardener, and a thinner or reducer.

The use of a 3K paint system is usually necessary when the paint is being used in industrial or automotive applications where a high level of chemical resistance, durability, and hardness are required. The addition of a thinner or reducer in a 3K paint system allows for better flow and atomization of the paint, resulting in a smoother, more consistent finish.

In automotive industry, the use of 3K paint system is common, it allows a better leveling of the paint and a better finish, also it allows to apply the paint in thicker layers, which is important for repair work, for example.

Another advantage of 3K paint is that it can be applied at higher temperatures and humidity than 2K paint, which makes it ideal for use in environments where these conditions are present.

Additionally, the use of a 3K paint system can also be necessary in certain industrial applications, such as marine and aerospace, where the paint must be able to withstand harsh environmental conditions, including exposure to chemicals, saltwater, and extreme temperatures.

In summary, 3K paint system is typically used in industrial and automotive applications where a high level of chemical resistance, durability, and hardness are required, also it allows a better leveling of the paint and a better finish and can be applied in thicker layers.
