Resin: Definition, History, Types, Functions & FAQ

by | Resin

Resin is mainly used as glue – to stick fibers together. In the art and jewelry industry, the resin is used for making furniture, trash bins, and various jewelry items.

What is Resin?

Resins are mixtures of organic compounds. It is a liquid compound that will harden under certain circumstances. 

Resin is different from plastic as plastic is derived from petrochemicals; on the other hand, resin mainly derived from plants. 

It can be said that resin is a form of unprocessed plastic and Solid resin is more versatile depending on how it can be formed.

History of Resin

The use of resin has a long history. Resin is a very unique compound. Amber is a kind of resin that occurs naturally. Some trees produce amber to protect their damaged part.

 In Ancient times, resins are used in beverages and smoked. Greek people named the Resin ‘electron’ as they learned that rubbing amber could produce an electric charge.  

The Mongols invented the world’s first composite bow which was bound together with natural pine resin. Around 1870 – 1930, scientists developed the very first synthetically-manufactured resins. Like trees, they protect their damaged part by producing amber, now manufactured resin is used to protect our floor, countertops, laminate, and making jewelry.

Types of Resin

There are various types of resin such as Polyester, Phenolic, Alkyd, Polycarbonate, Polyamide, Polyethylene Resins, Epoxy, silicone, etc. 

Some types are given below with their cost and use.

Polyester Resin

Polyester resin is a mixture of dibasic organic acids and polyhydric alcohols. This type of resin has excellent resistance to heat and flame. 

With time polyester resin tends to turn yellow and can be broken if it is dropped on a hard surface.

Polyester resin has a very unpleasant smell and it can be dangerous if we don’t wear a respirator and work without a hood.

Polyester resin cost is low. 

Polyester resin can be used for construction, auto repair of filters, fishing rods, decorative accessories, etc.

Epoxy Resins 

Epoxy resin is widely available and known as all-purpose resin. It has excellent heat and chemical resistance.

This is safe to use but needs to wear gloves and respiratory not needed.

It is used for laminate, flooring, surface coating, etc.

Polyurethane Resin

Polyurethanes are made of polyol and isocyanate components. They are great when mixed with other resins and have a high film elasticity.

It can be expensive if there is an increase in clarity.

It may be dangerous, some Polyurethanes should be used with a respirator and ventilation hood for safety.

It is used for insulation, adhesives, elastomers,  and foam liners for clothing.

Silicone Resin

Silicone Resin is made with the less reactive tetraethoxysilane or ethyl polysilicate and several disiloxanes. 

Earlier, it used to be made with sodium silicate and various chlorosilanes.

It can cost high if we want water clear silicone.

It is safe to use with gloves.

Silicone resin has high film and it is used for rubber, laminate, deformer, etc.

Acrylic Resin

Acrylic Resin has good tensile strength and is UV resistant. They are used for decorative panels, coating, signs, etc.
