Definition of Epoxy Resin

Resin, also called liquid glass, is a substance viscous, with a high density and solubility, with an intense odor and that reacts to the effect of heat. It is naturally obtained from the secretion of certain species of coniferous plants.

In many countries the tree from which this substance is obtained is precisely the resin pine.

For the app of this substance are normally used catalysts that produce heat and for this reason it is not advisable to use large amounts of resin. In any case, the catalysts serve to harden the materials. Once the catalyst and resin are bonded, the resulting material becomes a rigid plastic.

Different uses

The use of this substance has multiple practical applications.

- In dentistry it is used to restore form and functionality to teeth.

- In crafts it is used to join all kinds of materials (ceramics, paper, wood or that).

- It is used in the jewelery and costume jewelery sector.

- This substance is also used in manufacturing of paper, in paints and enamels, in pest control or in the manufacture of cleaning products.

There are three variants of resin: polyester, vinyl ester and epoxy

- The first is the most economical of the three, it has a high toxicity and is widely used to make surfboards.

- Vinylester is similar to polyester, but with some different characteristics.

- Lastly, epoxy resin is the most sophisticated and expensive of the three, but it has better mechanical properties.

Epoxy resin stands out for its versatility and for this reason it is highly valued in all types of sectors

As for its characteristics, the main ones are the following: it is a good thermal insulator, resists humidity, has adhesive properties and resists high temperatures. Trademarks of epoxy resin are made from a chemical reaction between two products: epichlorohydrin and bisphenol-a.

It is used in the preparation of continuous pavements for industrial use. This system is especially advantageous, since dirt on the joints is avoided. For this reason, this resin is ideal for floors in hospitals, schools, garages and offices. In the restoration of monuments it is a highly valued substance.

This resin is used to make adhesive products, to make welds and anchors, to repair nautical boats or to join blocks in the sector of the building.
