3 Resin Liners commonly used by relining contractors
Pipe relining involves the integration of a resin liner into the pipeline as it bonds with the old pipes and becomes the new fundamental pipes of the main sewer line. This method is becoming a very popular option for homeowners and a real estate owner due to the fact that the whole process of restoring the pipes is fast and causes nominal destruction at all. Different contractors use different resin liners. We’re going to take a look at the commonly used resin liners used by contractors today.
Epoxy Resin Liners
Epoxy resin is considered to be the toughest and the most reliable among the different types of resin liners. Unfortunately, the durable benefit of epoxy resin has a major disadvantage. You see, since its composition is very solid it takes a very long time to harden. Epoxy resins take the longest to be cured among the mostly used types of resin in the market. Plus, there is the issue of epoxy not suitable being mixed with different components since it will have negative effects to the sturdy structure of the resin liner. This is only the disadvantage of epoxy resin from its stellar benefits. The problem can be actually solved by creating schedules of the process ahead of time.
Resins start to solidify once it’s exposed to heat or is stop being exposed to extreme cold temperatures so by unfreezing the resins head of time; it will become easier to cure. Of course the schedule must be strictly followed so that there won’t be issues like the resin being cured before the project starts or the epoxy being still difficult to harden. Epoxy resin doesn’t contain any dangerous compounds or odour-producing chemicals like styrene so you don’t have to leave your home due to the emergence of chemicals if an epoxy resin liner is used for a pipe relining operation.
Polyester Resin Liner
Unlike epoxy, polyester can be mixed with other materials for longer storage and to have a faster curing process. It’s also the most affordable among the three most used resins in pipe relining so it’s no wonder that many relining contractors use this resin liner. Polyester has a lot of some possible problems than epoxy though. For one, polyester can shrink faster than epoxy so it won’t be as good as its first integration after many years of usage. It also has some chemicals that may cause harm to the repair crew or the people residing near the resin liner operation. So how is polyester resin still being used? Actually, polyester resin passes most requirements imposed by pipe repair agencies so it’s still definitely okay to use polyester. The problem arises in mishandling of the polyester or not using the necessary equipment. Many lateral lining contractors often avoid using polyester due to the concerns mentioned earlier.
Vinyl has the highest resistance against corrosion and chemicals amidst the three resins in this article. Also, it’s kind of a combination between epoxy and polyester but it’s still not as tough and dependable as epoxy. Vinyl ester resins mostly share its traits from polyester since vinyl has the same issues with polyester.
