A PVC solvent is an adhesive of a premium quality that is used for the fitting of PVC and UPVC pipes. The benefit of using this mixture is that it strengthens the pipes' bonding, sets fast, and acts as a suitable adhesive. It can be used to glue pipes, which are either PVC or UPVC, and have a diameter of 100mm. It is also used as an adhesive to fix drinking water pipes, sanitary pipes, wastewater pipes, irrigation pipes, etc. The crucial thing that you need to be aware of is, this cement is not glued. It is composed of wax, stabilizers, and fillings, which are amalgamated to form mixtures. 

The mixture works in two ways

  • It dissolves the wax
  • Makes the surface of the pipe and fitting ready 

As the mixture is applied, it melts the pipe's upper layer and the fitting, reducing the molecular structure, making it soft. When a taper is used later, then it fits in fast. As the fusion happens in the molecular structure, even when the mixture is vaporized, it remains strong. The stabilizers that it had help in retaining the properties of the solvent. The primary function of these stabilizers is to prevent oxidation and heat that may erode the mixture.  

When Should You Use Them?

It is preferred for joining pipes and fittings because it joins those surfaces very fast and can be easily relied on as a fixing method. This cement uniformly bonds the pipes creating a fused thermoplastic. These joints are also resistant to heat, temperature, pressure, chemicals for which it is chosen greatly. 

Different Kinds 

The PVC solvent cement composition remains the same for all types: solution of mixtures, fillers with wax, and stabilizers. The differential fact is its consistency, which makes it separate from one another. The consistency varies from one mix to another by the presence of the amount of wax in it. The additional amount of resin it has, tremendous is the consistency. With greater consistency, it can fx the joints and hold it for a long time. 

Keeping consistency as the parameter, it can be classified into three categories:

  • Regular bodied
  • Medium-bodied
  • Heavy bodied

Industrial Application of Solvent Cement

For all sorts of applications for industrial purposes, it is always recommended to use the heavy-bodied one. It is so because the heavy-bodied ones have a more consistent resin, which helps the fitting to be held tight for a long time. Besides this, a primer should also be used. The primer is a kind of softener that is applied first to loosen the pipe's molecular structure. Then the heavy-bodied should be used for enhancing the softening process.

Corrosive Application of Solvent Cement

The mixtures of this category do not contain fillers in them. They are designed specifically for this industrial system to deal with these highly corrosive applications. The absence of fillers is to ensure that no chemical can degrade the system. 

Procedure to Apply Solvent for PVC Pipes

In most cases, the process is hassle-free and does not require any critical techniques. But in some cases, there is a requirement of proper solvent welding depending upon the fluid and pressure that the pipe has to tackle. The process to apply the mixture for lines are as follows:

  • Step 1 Materials required
    • Two PVC pipes that you want to join
    • PVC Primer
    • PVC pipe solvent
    • Gloves
    • Paper
    • Towels
  • Step 2: As the solvent is obnoxious in smell, have a properly ventilated area where the fumes won't clog. Cover the surface on which you are working, as the cement may ooze at times. You can use paper towels also in this case as you can easily and quickly remove the excess cement before it starts to melt the pipe at unnecessary portions. You should wear gloves while working.
  • Step 3: Now open the can of the primer with a wrench. Pull out the applicator that is attached to it. Apply on each part of the pipe that is to be bonded. Be careful as the primer runs out like water. There will be excess, so clean it off with towels. 
  • Step 4: Now it is the turn of the cement to be applied. The cement, too, has an obnoxious smell and looks like liquid rubber. It also has an applicator inside. You need to pull it out. Apply the cement on the inner side of the joints. Do not put too much or too little, as putting too much will make the cement ooze out and ruin the fitting, and putting little will not strengthen the bond of the pipes.  
  • Step 5: The final and most crucial step is to push the cemented portion so that they may join. The motion of pushing is something that should be kept in mind. Pushing straight will harm the fitting by leaving a slight channel from which air and water can pass. The motion of fixing should be a simultaneous twisting of 9p degrees, which will help the fixing be equal.

The sustainability of this cement is the primary cause for which it opts as a joiner. It gives a good adhesion, fast setting and is also waterproof. It is also ideal for coupling any pipe. It can fix pipes, which endures any pressure. Thus it is one the easiest ways to use to fix your piping. You can stay assured that your pipes will remain appropriately joined by the use of this cement.
