Shelf-Life
The Shelf Life & Storage of Aspartech Products
Every Aspartech product is supplied with a recommended shelf life when stored in its original, unopened container under the storage conditions specified in the relevant Technical Data Sheet.
These dates are shown in the table and are used to ensure customers always achieve the optimum product performance.
However, it is important to understand that a shelf life is not the same as an expiry date. The recommended shelf life simply defines the period during which we can guarantee the product will perform exactly as specified without the need for further inspection.
Why Shelf Life Matters
Polyaspartic and Polyurethane based coatings are highly engineered chemical systems. Over time, all reactive materials slowly age, even inside sealed containers.
The quality of the formulation determines how well a product resists these natural ageing processes.
A well-formulated coating will remain stable for many months, while lower quality products begin to deteriorate long before they are used.
Aspartech - Superior In-Can Stability
One of the characteristics that sets the Aspartech range apart is its exceptional in-can stability.
Our chemists carefully select high-quality raw materials and formulate each product to remain chemically stable during storage. This means the product retains the characteristics it was designed to deliver when it is eventually used on site.
Unfortunately, not all floor coating products are formulated to the same standard.
Some lower-cost products begin to change as they age within the container. This gradual deterioration can affect important properties such as:
-
Viscosity and workability
-
Wetting and substrate adhesion
-
Cure speed
-
Bond strength
-
Overall installation consistency
These changes may not always be obvious to the installer, but they can introduce installation variability, reduce application quality and long-term performance. Aspartech products are specifically engineered to resist these effects, providing reliable storage stability and consistent performance whenever they are required.
Maximising Product Life
To achieve the longest possible storage life, we recommend:
-
Store products in their original sealed containers.
-
Keep containers in a cool (not cold), dry location away from direct sunlight.
-
Avoid prolonged exposure to elevated temperatures.
Following these simple storage practices will help maximise product life and maintain optimum product performance.
Quality You Can Rely On
Every Aspartech product is manufactured under our ISO 9001 quality management system using carefully selected raw materials and tightly controlled production processes. Combined with exceptional formulation stability, this gives installers confidence that each product will deliver the same reliable performance whether it is used immediately after manufacture or after an extended period of correct storage.
While the recommended shelf life shown in our Technical Data Sheets provides a conservative guide for guaranteed performance, the exceptional in-can stability of the Aspartech range means that unopened products stored correctly will often remain perfectly serviceable well beyond their stated shelf life.
