Vinyl ester resin is an example of a synthetic resin. [1] Synthetic resins are industrially produced resins, typically viscous substances that convert into rigid polymers by the process of curing. In order to undergo curing, resins typically contain reactive end groups, [2] such as acrylates or epoxides. Some synthetic resins have properties ...
In Europe, glue was not widely used until the period AD 1500–1700. From then until the 1900s increases in adhesive use and discovery were relatively gradual. Only since the 20th century has the development of synthetic adhesives accelerated rapidly, and innovation in the field continues to the present.

Fevicol is marketed as a white adhesive, described in company literature as a poly-synthetic resin.It is manufactured through the synthesis of formaldehyde and urea. [4]The product line includes various formulations designed for specific attributes such as bonding strength, impact resistance, curing time, sag resistance, shrinkage, versatility, fire resistance, shock and vibration resistance ...
