Gum glue is a type of reactive adhesive that forms a bond through a chemical reaction triggered by the presence of water. In essence, water acts as a catalyst, enabling the adhesive to cure and create a strong bond between two surfaces.
Here's a breakdown of key aspects:
-
Reactive Adhesive: This signifies that the adhesive undergoes a chemical change to create the bond. It's not simply a physical sticking.
-
Water-Activated: The defining characteristic is the need for water to initiate the bonding process. Without moisture, the adhesive remains inactive.
-
Chemical Reaction: The introduction of water causes the adhesive's components to react and crosslink, forming a robust and durable bond.
-
Applications: Gum adhesives can be used in various applications such as sealing envelopes, affixing labels, and certain types of packaging. The advantage lies in their dry state until activation, allowing for easier handling and storage.
Therefore, remember that gum glue isn't just any sticky substance; it's an adhesive whose bonding capabilities depend on the presence of water.
