Resin Types and Applications, Natural Vs Synthetic Resin

Resin, What is resin?

Resin refers to a group of solid or highly viscous substances of plant or synthetic origin. These materials are usually transparent or semi-transparent and have hardening properties.

Resins are used in a variety of applications including arts, crafts, construction, medicine, and industrial processes. They are classified into two main types: natural and synthetic.

Natural resin:

  • Plant resins:

The sap produced by certain plants such as the pine tree is known as the most famous plant resin. This type has been used throughout history for various purposes, including varnishes and adhesives.

  • Gum resins:

This type of resin is a mixture of vegetable and gum. One of the well-known examples of this is frankincense, which is obtained from Boswellia trees.

Synthetic or polymer resins:

Polymer resins are man-made through chemical processes. This material is widely produced for various applications. The most famous polymer resins are epoxy, polyester, and polyurethane. These synthetics are often used as adhesives, coatings, and molding compounds.

1- Epoxy:

Epoxy resins are known for their strong adhesion, high chemical resistance, and excellent durability. It works through a chemical reaction with a hardening agent. This type is used for various purposes such as adhesives, coatings, laminates, and in the production of composite materials.

2- Polyester:

Polyester resins are actually thermoset polymers that are made through a chemical reaction. This material shows good chemical resistance and is often used in combination with fiberglass to make composite materials.

Its Applications are commonly used in boat building, automotive applications, and making various molded products.

3- Polyurethane:

Polyurethane resins are versatile and have a wide range of properties. This material can be hard or flexible and is known for its high durability, impact resistance, and elasticity. It is used in coatings, adhesives, sealants, flexible foams, and various molding products.

4- Acrylic:

Acrylic resins are thermoplastic or thermoset polymers with good clarity, weather resistance, and UV stability. They can be molded and have excellent color retention. They are usually used in paints, adhesives, coatings, and in the production of acrylic glass (plexiglass).

5- Polyvinyl chloride (PVC):

PVC is a widely used thermoplastic resin known for its versatility, chemical resistance, and durability. PVC is usually used in pipes, cable insulation, clothes, inflatable structures, and all kinds of consumer goods.

6- Phenolic:

Phenolic resins are thermoset polymers with excellent thermal resistance, electrical insulation properties, and good strength. They are used in the production of molded products, laminates, and adhesives, especially in electrical applications.


These 6 types of polymer resins mentioned are the most famous examples of synthetic with special properties and for different applications. The choice it depends on the properties desired for a particular application such as adhesion, flexibility, transparency, or heat resistance.

In arts and crafts, the resin is commonly used to create glossy coatings on surfaces, encase objects, and create various art forms. In the construction industry, these may be used in composite materials for added strength and durability. In the field of medicine, special resins are used to fill teeth and prostheses. The specific properties and uses of it depend on its composition and intended use.

Applications in the paint industry

These materials have important uses in the paint industry and help formulate coatings with specific properties and performance characteristics. Different types of this material are used in paints, the choice of which depends on the desired properties of the final coating. Choosing the right one can play a significant role in the stability of it in question. Here are some of the common uses of resin in the paint industry:

  • Color base:

Resins act as a base material that holds pigments and other paint components together. They form a continuous layer on the painted surface and provide uniformity and cohesion to the coating.

  • Stickiness:

Resins increase the adhesion of the paint to the substrate (such as wood, metal, or concrete) and protect the paint from peeling or separating from the surface.

  • Durability and weather resistance:

Some resins contribute to the durability and resistance of the paint to certain weather conditions. They can protect the painted surface from environmental factors such as sunlight, moisture, and pollutants and prevent surface rusting.

  • Chemical resistance:

These materials can increase the chemical resistance of the paint and make it suitable for applications where the painted surface may come into contact with various chemicals or solvents.

  • flexibility:

Some resins increase the flexibility of the paint and prevent it from cracking or chipping on the applied surface. This feature is especially important in situations where the painted surface may experience movement or expansion and contraction.

  • Gloss and shine:

They affect the gloss of the paint. Different resins can be used to achieve different finishes, from high gloss to matte, allowing for aesthetic customization.

  • Quick drying:

Some types of this material help to reduce the drying time of the paint. These materials are often desirable in industrial or commercial applications where quick drying is essential.

  • Scratch resistance:

They can increase the scratch resistance of paint and create a protective layer. This feature helps maintain the appearance of the coated surface for a long time.

  • UV Stability:

UV-resistant resins are used to protect the paint and the underlying layer from the damaging effects of ultraviolet (UV) rays. This prevents fading and spoiling of the color and its underlying surface.

The common types of these materials used in the paint industry are acrylic, alkyd, epoxy, polyurethane, etc. The choice of resin depends on the intended application of the paint, the substrate, and the characteristics desired for the coating.
