DEN GANZEN ARTIKEL HERUNTERLADEN
Weld-On has been the industry leader in PVC / CPVC / ABS Klebstoff manufacturing for over seven decades. When you mention PVC glue or PVC Adhesive to a long-time Weld-On employee, don’t be surprised if they correct you and say Weld-On produces high-quality PVC / CPVC / ABS Klebstoff, not PVC glue. Even though the terms are used interchangeably in the industry, there is a big difference between PVC / CPVC / ABS Klebstoff and Adhesives.
The Differences Between PVC / CPVC / ABS Klebstoff 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 Klar (durchsichtig) 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 / CPVC / ABS Klebstoff is not PVC Glue or PVC Adhesive
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 PVC / CPVC / ABS Klebstoff. There are many types of uses for CPVC, PVC or PVC-U Rohr, 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 Rohr 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 / CPVC / ABS Klebstoff Works
When PVC / CPVC / ABS Klebstoff is applied to the surface of the PVC Rohr or PVC Anschlussstück (Verbindung), 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 PVC / CPVC / ABS Klebstoff is applied, the spaghetti molecules are tightly locked together, similar to cooked spaghetti that has been in a freezer. When the PVC / CPVC / ABS Klebstoff is applied to PVC Rohrs and PVC Anschlussstück (Verbindung)s, 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 PVC / CPVC / ABS Klebstoff joints using air, water pressure and lap shear tests, and the results are the same. The entanglement bond produced by PVC / CPVC / ABS Klebstoff results in a bond far superior to glue but even stronger than the Rohr.
The next time you hear an employee say Weld-On produces premium PVC / CPVC / ABS Klebstoff, not PVC glue or PVC Adhesives, you’ll understand why. For more information about Weld-On products, go to www.WeldOn.com.
