A resin is a viscous substance that can be converted into a rigid polymer when it cures. All resins will harden under certain conditions, for example, heat, exposure to light, or being mixed with a setting agent or hardener. From robust structures to intricate artworks, resins have emerged as the go-to choice for countless engineers, artisans and designers around the world. They can be naturally occurring or made synthetically to suit a range of applications and uses. Natural resins are organic substances that are fusible and can either be transparent or translucent. Synthetic resins have similar characteristics but are different chemically and can be clear. Some are referred to as a casting resin if they are a liquid before it polymerises and sets.Types of ResinEpoxy ResinEpoxy resin, a marvel of modern chemistry, delivers with its exceptional strength, durability, and versatility. Derived from a chemical reaction between epichlorohydrin and bisphenol A, epoxy resin boasts remarkable adhesive properties, making it an ideal choice for structural bonding needs and laminating. This remarkable material is lauded for its ability to resist corrosion, chemicals, and extreme temperatures, allowing it to thrive in a multitude of environments. Epoxy offers a high strength to weight ratio and dimensional stability, as well as adhesion properties which make them ideal for a wide range of applications. Whether it's for creating stunning artwork, patching holes, manufacturing aerospace components, or crafting durable, protective floor coatings, epoxy resin stands as a symbol of innovation and resilience.Polyester ResinSometimes referred to as unsaturated polyester resin or more simply polyester is a type of adhesive paste, filler and laminating resin. With its low cost, ease of use, and exceptional moldability, polyester resin is an excellent solution. The polyester resin normally comes as a pale, viscous solution or paste containing a polyester solution, normally styrene. They have a fast cure time and can be used as a sealant on a variety of materials, thanks to their resistance to chemicals and harsh weather. This versatile resin finds its place in various industries, including automotive, marine, construction, and consumer goods. From crafting lightweight boat hulls to designing eye-catching sculptures, polyester resin unveils a world of possibilities limited only by the imagination of its wielder.Resin ApplicationsThe applications of resins extend far and wide. They can be useful across a range of applications, but their main purpose is as a glue, to fuse or mould objects together. Some common uses include:* Adhesives
