Weld-On has been the industry leader in Cemento solvente manufacturing for over seven decades. When you mention PVC glue or PVC Adhesivo to a long-time Weld-On employee, don’t be surprised if they correct you and say Weld-On produces high-quality PVC Cemento solvente, not PVC glue. Even though the terms are used interchangeably in the industry, there is a big difference between Cemento solvente and Adhesivos.
The Differences Between PVC Cemento solvente and Glue
There are many types of glue. The most popular is Polyvinyl Acetate (PVA) glue, which is popular with woodworking, crafts and construction because it is water-based, dries Transparente and is safe to use. Its main ingredient is polyvinyl acetate resin, which means it can be easily diluted in water and is easy to clean up or removed if it’s still wet. Other popular glues, like super glue, epoxy and hot glue, are extremely effective in many situations; however, they are not designed for PVC piping applications.
Why PVC Cemento solvente is not PVC Glue or PVC Adhesivo
The basic function of glue is to attach two surfaces together, like wood, metal, plastics, and ceramics. When two surfaces are glued, they are connected together by the superficial properties of the glue. The glue’s strength comes from the ingredients within it, but it has a lot of limitations depending on the type of glue used and the surfaces it connects.
The opposite is the case when bonding PVC joints with Cemento solvente. There are many types of uses for CPVC, PVC or PVC-U Tubería, including pool and spa installation, transporting water for irrigation purposes, or moving corrosive chemicals safely. It is critical to ensure strength and dependability of the PVC welded Tubería to prevent unnecessary damage, protect people and equipment from hazardous materials or ensure the safe delivery of water to a destination. PVC joint failure is never an option.
How PVC Cemento solvente Works
When Cemento solvente is applied to the surface of the PVC Tubería or PVC Conexión, it softens or loosens the surface at a molecular level. The solvent unravels the interpenetrating polymer network (IPN) on the surface, which, on a molecular level, looks similar to cooked spaghetti. Before the Cemento solvente is applied, the spaghetti molecules are tightly locked together, similar to cooked spaghetti that has been in a freezer. When the Cemento solvente is applied to PVC Tuberías and PVC Conexións, the molecules become loosened. When pressed together and allowed to cure, the molecules get tangled with each other, which is called IPN entanglement, creating a bond much stronger than glue. Many tests have been conducted to test the failure point of Cemento solvente joints using air, water pressure and lap shear tests, and the results are the same. The entanglement bond produced by Cemento solvente results in a bond far superior to glue but even stronger than the Tubería.
The next time you hear an employee say Weld-On produces premium PVC Cemento solvente, not PVC glue or PVC Adhesivos, you’ll understand why. For more information about Weld-On products, go to www.WeldOn.com.
