Performance and Testing

1. Storage Life; Shelf Life: The maximum storage time during which an adhesive can still maintain its operational performance and specified strength under specified conditions.
2. Pot Life; Working Life: The time during which the prepared adhesive can maintain its usable performance. Synonym: Service Life.
3. Solids Content: The weight percentage of non-volatile substances in the adhesive measured under specified test conditions. Synonym: Non-volatile Matter Content.
4. Chemical Resistance: The ability of a bonded specimen to maintain its bonding performance after being exposed to chemicals such as acids, alkalis, and salts.
5. Solvent Resistance: The ability of a bonded specimen to maintain its bonding performance after being exposed to solvents.
6. Water Resistance: The ability of a bonded specimen to maintain its bonding performance after being exposed to water or moisture.
7. Ablation Resistance: The ability of an adhesive layer to resist the scouring of high-temperature flames and high-speed airflows.
8. Permanence; Durability: The ability of a bonded assembly to maintain its performance over a long period under service conditions.
9. Weather Resistance: The ability of a bond to resist climatic conditions such as sunlight, heat and cold, wind and rain, and salt spray.
10. Bonding Strength: The stress required to cause failure at the interface between the adhesive and the adherend or in the vicinity thereof in a bonded joint.
