Resins are widely used substances, not only in the decorative industry, playing an important role in various sectors, including chemical, construction, automotive, electrical, and many others.

They are polymeric materials with specific chemical and physical properties formed by natural or synthetic processes.

Resins are characterized by their viscosity in a liquid state and their ability to harden and become solid under appropriate conditions. They are often used as binders or coatings in various applications due to their resistance to wear, chemicals, and corrosion. Additionally, resins are known for their mechanical strength, electrical insulation capability, thermal stability, and ability to retain their shape over time.

There are different types of resins used in the industry, each with its specific characteristics and applications.

Alkyd resins are often used in the production of paints, varnishes, and adhesives, while polyester resins are commonly used in the production of composite materials and coatings. Acrylic resins are popular in the production of coatings, paints, and adhesives, while resins for hand laminating, spraying, casting, and winding are used in various industrial production processes.

The combination of properties that resins provide makes them key components in many industrial processes, enabling advancements in technology and production. Their diverse applications are reflected in numerous products we use daily, providing enhanced solutions in many industrial sectors.

Considering all these factors, resins represent an essential and dynamic part of the industry, continuously improving and transforming the way we produce, protect, and use various materials in everyday life.

Alkyd Resins

These resins are obtained by the polymerization of alkyds. Alkyds are polyester polymers formed by the reaction of polyols and polycarboxylic acids. Alkyd resins are used in the production of paints, varnishes, coatings, and adhesives.

Modified Alkyd Resins

These resins are variations of alkyd resins that have been modified by adding other materials, such as amino acids or epoxy resins. Modified alkyd resins have improved properties, such as higher chemical resistance and better mechanical properties.

Saturated Polyester Resins

These resins are obtained by the reaction of saturated polyesters and monomers containing double bonds. Saturated polyester resins have high chemical resistance and are used in the production of paints, varnishes, and composite materials.

Unsaturated Polyester Resins

These resins are a type of synthetic resins obtained by the polymerization of unsaturated polyesters. These resins are often referred to as UP (unsaturated polyester) resins. The main components of unsaturated polyester resins are polyols and unsaturated dibenzoic acids.

A characteristic feature of unsaturated polyester resins is their ability to react with styrene monomer. Adding styrene to the resins allows them to become more fluid and easier to apply in various industrial processes, such as hand laminating, spraying, or winding.

Unsaturated polyester resins are used in the production of a wide range of products, including composite materials such as fiberglass, fiberglass-polyester laminates, fiberglass-polyester pipes and tanks, as well as in the production of additives, coatings, paints, and varnishes.

These resins are known for their good mechanical strength, exceptional chemical resistance, and their resistance to UV radiation and atmospheric influences. Additionally, unsaturated polyester resins have good adhesion to various materials, making them suitable for use in the production of laminates and composite materials.

Acrylic Resins in Solution

These resins are synthetic resins obtained by the polymerization of acrylic monomers. Acrylic resins in solution are soluble in organic solvents and are used in the production of coatings, paints, and adhesives.

Industrial Process Resins

Hand laminating resins, spraying resins, casting resins, and winding resins are types of resins used in various industrial production processes.

Hand laminating resins are used for making composite materials by manually applying the resin to fabric or fiberglass.

Spraying resins are used for coating surfaces by spraying the resin in a fine form. Casting resins are used for making molds and casting materials into desired shapes.

Winding resins are used for winding fiber material impregnated with resin to form a pipe or vessel.

What are the Benefits of Resins in the Decorative Industry?

Resins have several useful advantages in the decorative industry:

• Aesthetic Appearance: Resins can provide smooth, glossy, and elegant finishes that enhance the aesthetics of decorative items and surfaces.
• Visual Clarity: Resins are transparent and have high clarity, allowing clear details and colors to be retained when objects are embedded in the resin.
• Wear Resistance: Resins provide durable protection against scratches, abrasion, and other damage, extending the lifespan of decorative items.
• Easy Application: Resins are easy to apply to various surfaces, whether by brushing, spraying, or pouring, facilitating the decoration process.
• Design Versatility: Resins can be colored or embedded with decorations, offering a wide range of possibilities for creative designs and personalization of decorative items.

FAQs

How to choose the right type of resin for a specific application?

When choosing the right type of resin for a specific application, several factors need to be considered. First, consider the characteristics you need, such as chemical resistance, mechanical strength, or transparency. Next, consider the environmental conditions, such as temperature, humidity, or exposure to chemicals. Also, check the specific recommendations of resin manufacturers and consult experts for advice and recommendations. Finally, testing and evaluating the resin under appropriate conditions can help in making the final decision.

How are resins applied and what are the procedures for their application?

The application of resins can be done in several ways, depending on the type of resin and its purpose. This may include brushing, spraying, pouring, vacuum infusion, or hand laminating. It is important to follow the manufacturer’s instructions and use the appropriate equipment, such as protective gloves, goggles, or a face mask, depending on the specific safety guidelines. Additionally, controlling the thickness of the application and properly drying or curing the resin are important steps to achieving the desired results.

What are the safety guidelines for handling resins?

When handling resins, it is important to follow the appropriate safety guidelines. This includes wearing personal protective equipment, such as gloves, protective goggles, and a face mask, to prevent direct contact with the resins. The rooms where resins are handled should be well-ventilated to reduce exposure to chemical fumes. Additionally, avoid ingesting resins or inhaling fumes. Following the safety instructions provided by the resin manufacturer and having well-trained personnel are key to safe handling of resins.

How are resins maintained and stored?

For the maintenance and storage of resins, several factors need to be considered. Resins are often stored in well-sealed containers in a dry and dark place, away from sources of heat or flame. It is also important to monitor the shelf life of the resin and use it before the expiration date. When handling resins, avoid contamination by foreign materials, such as dust or moisture, as this can affect the quality and performance of the resin. If the resin becomes thickened or loses its fluidity, consult the manufacturer or an expert for recommendations on possible thinning or reuse.
