Shelf Life
What is Shelf Life?
Shelf life is the time period during which an adhesive retains its specified properties and remains processable under defined storage conditions. This durability is crucial for quality assurance and cost-effectiveness in industrial applications.
Properties of Shelf Life
- Retention of original adhesive properties
- Stable viscosity and flow behavior
- Unchanged curing characteristics
- Consistent cohesion and adhesion
- Temperature and humidity-dependent durability
- Batch-specific documentation
Factors Influencing Shelf Life
- Storage temperature: Cool storage extends durability
- Humidity: Moisture curing adhesives particularly sensitive
- Light exposure: UV protection for light-sensitive systems
- Container tightness: Prevention of contamination and drying out
Storage Conditions for Different Adhesive Types
- 1-Component Adhesives: Longer shelf life with cool storage
- Dual Cartridges: Separate storage extends durability
- High Temperature Adhesives: Special storage conditions required
- Medical Adhesives: Strict documentation requirements
Shelf Life Measurements
- Viscosity measurements: Monitoring of flow properties
- Curing behavior: Testing of reactivity
- Mechanical properties: Strength tests after storage
- Aging tests: Accelerated testing
Optimal Storage
- Temperature control: Constant storage temperature
- Moisture protection: Dry storage environment
- IBOA-free systems: Improved storage stability
- First-in-first-out principle: Batch rotation
Shelf Life Extension
- Deep-freeze storage: Drastic extension of durability
- Protective gas packaging: Prevention of oxidative aging
- Stabilizers: Additives for durability extension
- Contact Adhesives: Special storage conditions required
