Spray/ Dip Treatment

As a trusted partner in industrial coating, Leo Surface Coatings is a manufacturer of spray and dip pre-treatment systems in India, covering a crucial phase of surface preparation before paint or powder is applied. Our industrial surface pretreatment equipment cleans, conditions and converts metal surfaces through a continuous pre-treatment washing system, giving optimal adhesion and long-lasting corrosion resistance. Every system is built to support turnkey paint shop EPC solutions and works with our powder coating lines and industrial liquid coating booths, for clients across India, the UK, the USA, Germany and international markets.

  • Leo Surface Coatings spray and dip pre-treatment systems follow a proven, multi-stage process to deliver the best results in preparing metal surfaces for industrial coating. As a trusted provider of industrial surface pretreatment equipment, both our spray systems and continuous pre-treatment washing systems follow similar chemical stages while offering adaptable application methods. Built to support turnkey paint shop EPC solutions, our systems meet the precise requirements of any high-volume paint shop or industrial coating line across India and global markets.

    Typical stages include:

    1. Degreasing: Removing oils, grease, and other contaminants from the surface using our industrial surface pretreatment equipment.

    2. Alkaline cleaning: Removing rust, scale, and other inorganic matter to prepare the surface for coating.

    3. Rinsing: Removing chemicals from the previous stage to maintain process consistency.

    4. Conversion coating: Forming a protective layer on the metal surface to improve adhesion a core function of our spray and dip pre-treatment systems.

    5. Passivation: Sealing the conversion coating to prevent further oxidation and ensure long-term corrosion resistance.

    This staged approach ensures consistent surface quality across automotive, heavy engineering, and general industrial applications a key reason Leo Surface Coatings is trusted for turnkey paint shop EPC solutions in India and worldwide.

  • Leo Surface Coatings spray pre-treatment systems apply chemicals onto the workpiece using precision nozzles to deliver the best results for high-volume production. As a leading partner for industrial paint shop operations and automotive component coating lines, our systems ensure maximum processing efficiency and even coverage—backed by deep engineering expertise in spray and dip pre-treatment systems for clients across India and worldwide.

  • Workpieces are immersed in chemical tanks as part of our dip pre-treatment systems, ensuring thorough treatment across the surface. This method is suitable for complex shapes and large components, making it ideal for heavy engineering and industrial coating applications. It can be slower than spray pre-treatment but ensures complete coverage part of Leo Surface Coatings range of spray and dip pre-treatment systems trusted by clients across India and worldwide.

Frequently Asked Questions

Everything you need to know about our industrial spray and dip pre-treatment systems, plant configurations, and custom engineering.

Spray pre-treatment applies cleaning and conversion chemicals through precision nozzles and is well suited to high-volume production. Dip pre-treatment immerses components in chemical tanks, making it effective for complex shapes, large parts, and areas that are difficult to reach with spray.

The best system depends on the material, component size and shape, production volume, coating type, required corrosion resistance, available floor space, and process chemistry. Leo Surface Coatings can assess these requirements and recommend a suitable spray, dip, or combined system.

A typical line may include degreasing, alkaline cleaning, rinsing, conversion coating, passivation, and drying. The exact number and sequence of stages are selected according to the substrate, coating specification, and required finish.

Yes. We can evaluate an existing paint shop, coordinate the pre-treatment line with downstream painting or powder coating equipment, and provide a solution that fits the available layout and production requirements.

Useful details include the workpiece material, dimensions and weight, production volume, conveyor speed, coating process, desired corrosion protection, and available installation space. Photos, drawings, or sample parts can also help us prepare an accurate recommendation for clients across India, USA, Germany, Japan, South Korea, UK, Vietnam, Thailand, and UAE.
