World Class Painting System

Pre-Treatment System

TECHExpert pre-treatment and cleaning products are designed around the latest environmentally friendly water-based solutions. Our pre-treatment systems have special provisions in their design to get the best out of both sprays as well as dip types of pre-treatment systems. We have a wide range of seven tank dip systems that provide a perfect upgrade from any other conventional method, combining superior cleaning with a phosphate finish.
For more than a decade, we have been using conveyorized multistage spray pre-treatment lines. Over the years we have strengthened our experience which has led us to become competent enough to supply high-volume multistage plants. Our plants run on Zinc Phosphate, Iron Phosphate providing conversion coatings on Steel, Aluminium, or Zinc.

Pre-treatment systems in the paint and coating sector are crucial operations aimed at preparing a surface for coating application. These systems guarantee that surfaces are clean, devoid of impurities, and ready to form a strong bond with the coating, thereby enhancing its durability and functionality. Below is a summary table detailing the description, advantages, and applications of pre-treatment systems.

A collection of chemical or mechanical procedures that clean and prepare surfaces made of metal, plastic, or composite materials prior to coating application. This includes cleaning, degreasing, rinsing, surface conditioning, and chemical transformation.        

  • Cleaning & Degreasing: This step removes oils, dirt, and contaminants from the surface.
  • Mechanical Preparation: This involves sandblasting or grinding to eliminate rust or mill scale.
  • Conversion Coating: The application of phosphate or chromate layers enhances the bond with the substrate, improving adhesion and corrosion resistance.

Advantages of Pre-treatment Systems

Benefit

Description

Enhanced Adhesion

Pre-treatment improves the connection between the coating and the substrate, ensuring a stronger bond, which leads to a lower incidence of issues such as peeling or flaking.

Protection Against Corrosion

Conversion coatings like phosphates and chromates offer a protective barrier that reduces corrosion, thereby extending the life of metal components in challenging environments.

Increased Durability

By guaranteeing a clean, properly prepared surface, pre-treatment systems contribute to the longevity of coatings, even under demanding conditions like exposure to moisture or chemicals.

Aesthetic Enhancement

Pre-treated surfaces facilitate a more uniform application of coatings, minimizing surface imperfections and achieving a smooth, high-quality appearance.

Cost Savings

Effective pre-treatment minimizes the necessity for repairs or reworks, saving both time and money in both the production and maintenance phases.

Environmental Impact

Eco-friendly pre-treatment techniques, such as those based on silane or zirconium, significantly reduce the reliance on hazardous chemicals and minimize waste, thereby complying with environmental standards.

Use of Pre-treatment Systems

Industry

Use

Automotive

Facilitates the adhesion of paints and coatings to vehicle bodies and components, thereby preventing corrosion and enhancing the longevity of the vehicle.

Aerospace

Pre-treatment is essential for the coating of aircraft parts, ensuring their resilience against severe environmental factors such as UV radiation, extreme temperatures, and corrosion.

Construction

Steel and aluminum elements in construction are pre-treated to withstand weathering and rust, thereby maintaining structural integrity and ensuring long-term durability.

Marine

Metal components that are exposed to saltwater and moisture undergo pre-treatment to safeguard against corrosion, thereby prolonging the lifespan of ships, boats, and marine equipment.

Appliances

The pre-treatment of surfaces in household appliances enhances coating adhesion, prevents rust, and provides a smooth finish, contributing to both aesthetic appeal and durability.
