APPLICATION OF INDUSTRIAL PAINT

The particularly aggressive industrial environment is one of the biggest challenges in terms of corrosion protection.

At Decoman, the optimization of processes and the continuous improvement of our application equipment, places us firmly at the forefront of treatments for the protection of industrial surfaces in adherence with current UNE standards.

Industrial paint and surface treatments protect structures against the pressures to which they are subjected, and ensure a better aesthetic appearance, increasing their added value.

SERVICES:

► Application of anticorrosive and adhesive primers in epoxy bases and polyurethanes.

► Anti-corrosive finishes based on epoxy, polyurethane, acrylic, anti-caloric silicone, etc.

► Application of paints on metal surfaces: supporting structures, silos, pipes, tanks, etc.

► Protection and treatment of pipes and tanks with special treatments for food and drinking water.

► Protection and treatment of underground pipes and tanks.

► Waterproofing and painting of chemical tanks, anti-spill buckets, etc.

► Claddings and applications for the naval industry.

► Industrial maintenance.

CONCEPTS: 

• Corrosion:

It is an electrochemical process in which steel is transformed into iron oxide under the essential action of moisture and oxygen.

This waterproof barrier is created by the paint. It is therefore of the utmost importance to use products of the highest quality.

The quality and thickness of the paint will determine its protective capabilities, the higher the humidity and oxygen, the more difficult it will be to affect the structure.

• Waterproof barrier (Painting):

The paint is a product that, in liquid or paste form, is transformed by a curing process into a solid, plastic and adherent film that both protects and decorates.

• Binders: They are the basic components of paint. The properties of the paint depend on them.
• Pigments: They give colour and opacity to a coat of paint.
• Solvents: They facilitate application. Without them, paint would have very high viscosity.
• Additives: They act specifically to improve the quality and characteristics of the paint.

• Types of paint:

• Primers: First coats of paint in direct contact with the structure to be painted. Their function is to serve as an anchor for subsequent coats and prevent oxidation through anticorrosive pigments.
• Intermediate layers: They are applied on the primer in some processes. The pigment/binder ratio is inferior to those of primers but superior to finishing paints.
• Finish: The finish is applied as the final coat. Formulated to ensure optimum waterproofing and durability. A finish can be glossy, satin or matt.
• Varnishes: They are coats consisting of binders and solvents. Varnishes provide a clear/transparent finish.

• Characteristics of paint:

Any type of paint is defined by a series of characteristics, which are used by both manufacturer and user to establish whether it complies with what is specified.

• Liquid paint: Stability, viscosity, specific weight or density, solids content by weight or volume, performance, product life, dilution, type of application and drying time.
• Dry paint: Appearance, scratch resistance, salt spray resistance, gloss, adhesion, weatherproofing, coverage, flexibility, yellowing, impact resistance, temperature resistance and hardness.
