In chemistry, resin compounds are solid substances that are usually easily converted to polymers. These materials are easily fused with other synthetic resins and, since they can be both organic and synthetic, can be easily mixed with other compounds to make a much sturdier material.
Resin compounds play a vital role in pipe relining. In fact, they can be considered master pieces of the process. Without the resins that make up the liner, there will not be any pipe relining process taking place. Unknown to most homeowners, there is a number of different resin compounds they can use to reline their pipes. The reason for this variation is that the different types are modelled to specifically fit and work under certain types of pressure, temperature, and stress that a specific environmental setting can pose. To help you choose the perfect resin compound for your pipe liner, here are 5 of the most dependable ones:


Among the varying compound variations, this type of resin is the most commonly used one. This is mainly because this one is the best type of resin. An Epoxy resin has a three-dimensional density that aids to higher performance under different stressors. This means that when your pipe is damaged due to corrosion or the overbearing dead load above it, you can be sure that by relining it with epoxy resin, you can now be sure that the structure will hold for a long time while preventing calcification and corrosion from penetrating the surface effectively.
There are also setbacks with this resin compound and those are; requiring heat during the curing process to make the downtime shorter, possible complications during installation and the upfront cost is quite expensive.


Polyester resins are known to be the simplest resin among the variations of resins used in pipe relining. One advantage of this resin compound that makes pipe relining contractors gravitate towards this is that it is essentially child’s play to mix the compound. That, and the fact that this does not take much effort in installation, curing and mixing. But since the mixture is composed mainly of dibasic acids such as the fumeric acid, the ease in installation does not affect the quality of service it renders.

Vinyl Ester

This resin compound is just like the Polyester, only better. This is basically a mixture of Polyester resin and Epoxy resin. Its curing and installation process is much simpler and is quite hassle-free compared to the first two types. Its performance pioneers on having high resistance against root intrusion, calcification, durability and structural integrity. However, its setback is that it comes for a certain price.


This compound is an enhanced polyester compound. One of its best features is that it can withstand an environment that has the thermal degree of 55 degrees. This is also one of the reasons that make this type of resin ungodly expensive. However, there is no doubt that the high price of the resin is well-worth its performance against corrosive and damaging factors.


Also known as “ortho”, this resin compound is one of the cheapest resin compounds around. However, even though it is not as expensive as the rest in this list, it still offers impeccable performance against corrosion and has a very impressive thermal stability. This also has a plausible mechanical property that makes it suitable for underwater usage with a temperature withstanding 50 degrees.
