Liquid coating and painting

Liquid coating is a treatment that can be applied to objects of all shapes and sizes and is available in a variety of colours and finishes.


Liquid Enamel Painting

Liquid painting is a treatment for surface metals relying on a spray gun. The coating is sprayed on the surface in one or more layers depending on the type of liquid enamel used and the goals of the painting (primer, finish, intermediate layer).

Industrial liquid paint may be applied to all types of metals and it has a high elastic resistance to impacts, chemical substances, and fire (for certain types of paint), as well as high corrosion protection.

Types of Liquid Enamel Painting

Epoxy Resin Enamels

This type of paint is the ideal choice for protecting metal surfaces from chemical agents due to the high corrosion protection.

The coating is very hard and difficult to scratch, making it resistant to water and impacts. It can be used as a finish, primer, or intermediate layer.

Polyurethane Enamels

Oil based, this type of painting is suitable for both metals and plastic. It has a shiny finish and offers excellent resistance to solar radiation.

Polyaspartic Enamels

With a higher quality than the other types of enamels just mentioned, this solution is applied by highly specialized personnel. The paint is applied in a single layer and dries very quickly. The advantage is an increase in productivity due to its faster application and drying.

High-Temperature Liquid Enamels

Used for particular needs, high-temperature liquid enamels are ceramic paints developed precisely to resist solvents, thermal shocks, and very intense heat on the order of hundreds or thousands of degrees. As for corrosion resistance, the high-temperature paint is better compared to other coating methods.

Ideal for coating mechanical parts such as heater, car, and motorcycle parts (mufflers, manifolds, exhaust pipes) exposed to very high temperatures or the action of chemical substances, oils, and benzene, high-temperature paint is a decorative, functional choice that guarantees high-impact, long-lasting performance.

Liquid Electrostatic Painting

Electrostatic painting is a technique that yields quality results with notable paint savings compared to classical treatments, along with a reduced environmental impact because the enamels are free of solvents. It also creates a perfectly uniform layer without drips.

With industrial electrostatic painting, known internationally as e-coat, the surface is coated with a film of electrically deposited resin.

The particles of liquid paint are charged electrostatically, nebulized, and sprayed onto the material with an opposite charge by means of a spray gun. The force of compressed air and opposite charge therefore work on the particles of paint simultaneously.

Water- or Solvent-Based: Different Compositions of Liquid Paints

Liquid industrial paints may be water or solvent based. Depending on their composition, they have different characteristics and application techniques.

Solvent-Based Liquid Paints

Liquid industrial enamels encompass a wide range of treatments, diluents, catalysers, and paints.

They are used for painting surfaces that require high resistance against chemical agents, abrasions, and impacts. In fact, they are widely used in the automotive and agricultural sector.

Water-Based Liquid Paints

Their great advantage is certainly creating a film with high corrosion resistance, in addition to maintaining the colour long term. With respect to the solvents, they are free of toxic substances and are therefore not toxic for people or the environment. Ideal for companies that must or want to comply with EPA standards.

Sectors of Application for Industrial Liquid Painting

Liquid enamel paint is suitable for all types of surfaces, especially the surfaces of mechanical parts. It is also used when multiple layers are applied to prevent metal corrosion.

In industry, liquid painting is applied in the following sectors:

  • metallurgy plants;
  • power plants;
  • military equipment;
  • the rail sector;
  • the automotive industry;
  • any activity related to the wood industry;
  • medical instrumentation;
  • agricultural machinery.

The Advantages of Liquid Painting

Liquid paint has various characteristics that make it the ideal solution for coating metal and plastic surfaces.

Precision: Application of the liquid paint with a spray gun guarantees high precision, reducing the drying time.

Minor pretreatment: Even if it is always necessary to degrease and rinse the surface, this process is easier with liquid paints than with powder paints.

Excellent finish: The spray gun also ensures an excellent appearance due to the uniform distribution of the enamel, which also creates a resistant protective layer. Micro bubbles are also avoided, which are responsible for lower effectiveness of the paint.

High adaptability to surfaces: Some liquid enamels can be dried without placing the parts in the oven, because they require lower temperatures to dry. The surfaces on which these coatings are applied therefore do not necessarily require a high temperature resistance. The problem of possible damage to more heat-sensitive parts is therefore resolved.
