Resin is a semisolid secretion of plants and trees. It is a viscous liquid, composed of non-volatile solids and volatile terpenes, such as monocyclic terpenes limonene, beta-pinene, alpha-pinene and terpinolene. Synthetic resins are viscous liquids that have the ability to solidify. They are formed by the addition of an acid and an alcohol with organic compounds. Typical examples of resins include the forms of epoxy , vinylester and polyester.
The physical characteristics of vinylester fall between those of epoxy resin and polyester, and it is used as an alternative to both. Vinylester can withstand high levels of water and is corrosion- and chemical-resistant. Vinylester resin is used in construction and for the repair of bridges.
Polyester resin can withstand high temperatures without form distortion. There are two major types of this product: orthophthalic polyester and isophthalic polyester . Orthophthalic type is the standard version used for household applications; isophthalic material is used in marine and industrial applications for its higher durability. It is also used in construction, vehicles, textiles, packaging and luggage.
Let’s describe epoxy type in detail next.
Epoxy resins have wide range of uses. For example, resins that are cured through exposure to ultraviolet light are commonly used in fiber optics, optoelectronics, and dentistry. Industrial tooling applications use them to make laminates, castings, fixtures, and molds. In the electronics industry, these material can be used to make insulators, transformers, generators, and switchgear.
Types of epoxy resins include bisphenol A, bisphenol F(also known as 4 4′-dihydroxydiphenylmethane), modified bisphenol A and modified bisphenol F. It has a pungent odor and is best applied in a well-ventilated area. Around your home, this material can be valuable for repairing china, pottery, glass, wood, metal, and leather objects. Epoxy product can be used as repair material for marine applications, but they should not be applied on the outer layer of a boat because UV light exposure will eventually cause the resins to deteriorate.
In additon, the material is valuable as a crafting supply. It is suitable for making rings, earrings, pendants and bracelets. The resins cures to a hard, clear plastic. It makes a protective coating over jewelry elements, but its real beauty is as a focal piece. Seal small water-proof objects in the product so they look as though they are floating in glass. Use anything from hard candies to scrapbooking embellishments as inclusions in your resin jewelry. The chemical is easy to work with and even a novice can turn out attractive, professional appearing pieces.
