What is resin?
Resin is a two-part material that when mixed together will harded into a plastic. When resin is poured into a mold, it will take the shape of the original molded object when it is cured. The 3 main types of Resins are Epoxy, Polyster and Poly-Urethane based. Each type of material requires a base and then an activator to be mixed to cause a chemical reaction. When the reaction is complete the casting can be removed from the mold for clean-up and use according to your needs. Most resins give off an odor that can be offensive, even it is used in open well-ventilated spaces. In the case of the Epoxy and Polyster resins the mixture can be tricky because the per cent of activator is usually different from the amount of the base. Also it not unusual for these resin to take hours to set-up and sometimes a full 24 hours is necessary for complete curing. Polyster resins have the bad habit of staying quite sticky until the last possible moment during the cure process. One advantage of that these
Resin is a natural or synthetic compound which begins in a highly viscous state and hardens with treatment. Typically, resin is soluble in alcohol, but not in water. There are a number of different classes of resin, depending on exact chemical composition and potential uses. There are numerous applications for resins, ranging from art to polymer production, and many consumers interact with products which contain resin on a daily basis. Natural resin comes from plants. A classic example is pine sap, which has the characteristic sharp odor of terpene compounds. As anyone who has interacted with pine sap knows, the substance is very viscous, but it hardens over time. A number of other plants produce resins, and plant resins have been used by humans for thousands of years. Some plants exude a similar substance called gum or gum resin which does interact with water. Gum tends to be softer and more malleable than resin. Plant resin can be clear to dark brown in color, and it varies in opacit
“Resin” is the common name for a class of casting polymers typically requiring two parts. When the two parts are mixed, they produce a chemical reaction and generate exothermic heat, causing the material to harden and fuse into a solid form. The result is a type of plastic. There are many types of resins available, and new formulations are continually being developed for various uses and applications. The color, strength, pouring viscosity and many other factors vary among formulations. Auto-body putty is one commonly seen form of resin, as well as polyester used for piano casings, airplane wings, and many products are structurally laminated with resins. How durable are resins? Resin is generally considered to be long lasting and is not biodegradable. It will not rust, oxidize or decompose as some other materials may do over time and is unaffected by water or normal temperatures. While not as strong, nor malleable as metal, it is generally as strong as and not as brittle as ceramics. D
