Here's how the Liquamelt system works: The room-temperature liquid goes through the TurboActivator component, a device about the size of a 16-oz water bottle, where it's rapidly heated to between 350 and 400 deg F. The heat activates the material and turns the water component in the formulation to steam, which provides a foaming action when the adhesive is dispensed. According to Mancuso, competitive foaming systems inject gas or other materials to foam their adhesive. Here, this happens naturally and effectively.
