Blue Sticky Wax Super flexible and tough. Best for articulating models. Quick setting, wax-based adhesives used to create a fast, rigid bond between two wax surfaces. Their properties are ideally suited for dental crown & bridgework, as well as attaching patterns to sprue assemblies. They will not hinder melt-out and burn-out cleanly. The wax is also known as “model cement” and is used to hold or weld material or pieces together. It can also be used to sprue connect or repairs wax patterns. The wax is melted with a gas flame and used as a wax “glue”. To remove the wax, just reheat it and it will melts cleanly away without residue. The wax is highly tenacious (strong), hard, fast-setting and very adhesive. It flows easily, sets firmly, and is rigid at room temperature.
