Pot life, also known as usable life or working time, refers to the period during which a thermosetting resin or adhesive remains workable after the addition of a hardener or additive. This duration ends when the system's viscosity increases to the point that it's no longer usable. Factors such as the type, amount of hardener, additives, and ambient temperature all influence pot life. This metric significantly impacts the applicability of coatings and the performance of the cured layer. It's crucial to apply coatings before their pot life expires. Exceeding the pot life alters the coating’s viscosity and reduces its performance. For instance, if a two-component coating is mixed and left for too long before application, its viscosity increases, its performance decreases, and it may even become unusable due to gelling.
Polyaspartic polyurea is a two-component material, used in both coatings and adhesives, that requires a hardener. Its short pot life is primarily due to the high reactivity of the polyaspartic resin's primary amine functional groups with isocyanate hardeners. While this grants polyaspartic polyurea rapid drying and low-temperature curing properties, it also shortens its usable period.
