Methyl acetate

Natural or synthetic compound resin is very sticky and hard under difficult conditions. Usually soluble in alcohol, but not soluble in water. This compound is classified in various ways depending on the chemical composition and its use. It also has many uses in art, polymer production, and many daily consumers with resin-based products. 

The natural resin is obtained from the plants. The best example of this is the pine tree sap, which has a terrible smell of terpene compounds. As you know, this material is very sticky, but it becomes stiff over time. A number of other plants also produce resins, and these materials have been used by humans for thousands of years. Some plants digest the same substance called gum, which does not react with water and is softer and more flexible. 

The color of the resin varies from transparent to dark brown, and its hardness and opacity vary. Some of them are very volatile because they contain unstable compounds. A mistake in detecting resinous trees can also cause disastrous events because some of them contain heptane, which is a flammable and explosive hydrocarbon.  

The famous amber material is also obtained by the hardening of the plant's resin and is often found in dark golden color, which is the typical color of the plant's resins. Amber is also seen in other rare colors like blue. 

For thousands of years, humans use natural resins. Pine resin is used to sew boats, balm bodies, utensils and other uses. It is also used in the manufacture of varnishes, polishes, inks, perfumes, jewelry and many other objects. 

With the advancement of technology, humans discovered that this material could be converted into the polymer, and later that artificial resin was discovered. In most cases, polymers are made with synthetic resins that are cheaper to clean and refine. The types of synthetic resins are more stable, more predictable and uniform than natural resins because they are made under controlled conditions and there is no possibility of gross production. They are made by combining chemicals in the laboratory and the result of the reaction is the formation of viscous compounds. This material can be used in the manufacture of plastics, paints and many similar materials instead of natural resins.  

Types of resins are: 

  • Polyester resin 

• Epoxy resin 

• Winstar resin 

• Phenolic resin 

• Other resins
