Chemicals can be very useful in many ways one of the chemicals is known as the epoxy resins what exactly this chemical is or what you can get from it? Let me tell you some chemical background of this first. This is also known as the copolymer, the formation of this one chemical requires the combination of two different chemicals. These two chemicals are “resin” and the “hardener”.
Epoxide group is fond on either end of the short chain polymers, or monomers, which is resin. Bisphenol-A and epichlorohydrin are the two most common chemicals which produce epoxy resins, through a chemical reaction. Triethylenetetramine or (TETA) is the example of hardener that is consisted of polyamine monomers. After mixing these compounds together, the Epoxide groups will react with the amine groups which will form a covalent bond. Epoxide group has the ability to react with each and every NH group, in result of these reactions the polymer becomes heavily cross linked, and is thus strong and rigid.
Epoxy resins-based materials can be utilized in different ways, and they are extensive, these materials can be used in adhesives, composite materials and coatings, carbon fiber and fiberglass reinforcement (although vinyl ester, polyester resin for FRP and some of the other thermosetting resins which can be used for glass reinforcement plastic).
Epoxy resins are also available for the consumers and can also be used in marine applications. You can find them in hardware stores packed separately hardener and resins; they must be mixed immediately before you need to use them. Mariners also buy epoxy resins and are available at the boat shops; it is used for the repairing in marine applications. You cannot use it in the outer layer of the paint because it will deteriorate if exposed to the UV light.
You can use them during assembly or boat repair, and then conventional for coating or two part polyurethane paint is provided for the UV protection marine varnishes is also used for the UV protection. The mariners use epoxy resins at two main areas, due to the mechanical properties relative to the polyester resins, it can be used in the manufacturing of components, especially when the high weight strength ratio is required for commercial use. The second use of epoxy resins in marine is for strength; it can be used for filling gaps and has excellent adhesion to many materials.
Epoxy resins components should be mixed very precisely in order to get the third chemical. Depending on the properties required. You can use the ratio of these two components from 1:1 or over 10:1 but you should mix it exactly to get the best results. The result that you will get from it will be the precise thermo setting plastic. The final product may be varying if you use different type of hardeners with epoxy resins. The hardeners or hardener should be protected as it is chemically more active and should not expose to moisture. It should be kept in safe place, which should be out of the reach of children.
