One of the materials needed in the pipe relining process is the resin compound. It plays an important role in the process. There are various kinds of resin compound in the market that you can choose from. They have different features and are applicable to a specific situation and environment. Here are the 6 most common used resin compounds in plumbing.
There are various kinds of resins that you can purchase in the market. Among these resins, the epoxy resin is indeed the best kind of resin that you can use. This is mainly because of the three-dimensional density it contains and its high-quality performance. Behind every advantage, there will also be some disadvantages. The usage of epoxy resin also has some setbacks which include the following:
● This type of resin is quite expensive
● In the curing process, heat will be required
● Expect some complications during the installation process
The polyester resin is known to be the most unsaturated and the simplest type of resin. One main advantage of using this resin is, this compound is quite simple to mix as you won’t need to exert much effort. Also, it will not affect the performance and the firmness of the material. The polyester resin is made through the use of polymerization of various dibasic acids which include fumaric acid and maleic anhydride when using diols to offer ester in the mixture.
3. Vinyl Ester
This type of resin is a better version of the polyester resin. This is created by mixing it with the epoxy resin. The vinyl ester is easy to install and the process is quite hassle-free. The curing process is also not that hard and offer features which come from the polyester which has such an unbelievable performance. This includes its high resistance against root intrusion, durability and its structural sturdiness. However, it also has their setback which is quite expensive compared to the isophthalic resin compound.
The isophthalic resin which is also known as “iso” is an enhanced polyester compound. This resin compound has a thermal resistance of 55 degrees. Due to this, this resin compound is much more expensive compared to the other kinds of resins. A high-priced resin can guarantee you a better performance. This includes its high resistance to corrosion and factors that can damage your plumbing system.
The orthophthalic resin is also known as ortho. This is one of the low-priced resin compounds available in the market and is a widely known commodity of FRP industry. This type of resin is highly resistant to corrosion and an excellent thermal stability. Orthophthalic resin also has an exceptional high mechanical property. This resin can work well on seawater and water supply at a temperature resistance of 50 degrees.
This resin compound is a result which is created by mixing phenol with formaldehyde. It cures itself through the help of pressure and heat once stimuli which are used in curing is not provided by the external curing agents. It is known to the public because of its reasonable price. While curing, the resin becomes resistant to fire without the help of mineral fillers and fire retardant additives. This resin can create carbon composite with an impressive resistance to temperature. However, this is only possible when it is properly cured. Phenolic resin also has its own setbacks which include:
● Curing process would take time
● Limited range of colour options
● Acquires a high level of curing temperature and pressure
