What happens to adhesive properties when glue exceeds its pot life?

When glue exceeds its pot life, it undergoes a chemical reaction that can lead to hardening, causing it to lose its effectiveness. Pot life refers to the period during which an adhesive remains usable after it has been mixed, during which it maintains its intended characteristics of viscosity and bonding strength.

Once this period is surpassed, the adhesive begins to cure or set beyond the point of practical use, thereby reducing its capacity to adhere effectively to the surfaces intended for bonding. This hardening process can create a thickened consistency, making it difficult to apply and diminishing its overall bonding quality. Therefore, acknowledging the importance of adhering to the manufacturer's recommended pot life is critical for achieving optimal bonding results in any adhesive application.
