Saffety, Handling & Storage Guidelines
1.For Safe Operation & Mixing

• Safety First: Operate in a well-ventilated area, away from ignition sources. Avoid skin and eye contact.
  
• Mix as Needed: Estimate quantity based on the 40-minute pot life to avoid waste.
  
• Adapt to Conditions: Preheat Component A if temperature <15°C; use heat-assisted curing if humidity >85% to prevent surface whitening.
  
• Safe Keeping: Keep out of reach of children.

2.Storage And Shelf Life

• Storage Conditions: Store in a cool, dry place below 25°C (77°F). Keep away from direct sunlight, heat sources, and humid environments.
  
• Packaging & Stability: The product has a shelf life of 6 months from the date of manufacture when stored unopened in its original container under recommended conditions. Once opened, reseal tightly and use as soon as possible. Do not leave exposed to air for extended periods.

FAQ:

Q1: What's the main difference between manual and mechanical dispensing formulas?
A: The manual formula offers longer pot life (15 mins) for detailed hand work; the mechanical formula cures faster for automated batch production. Both deliver identical cured properties.

Q2: What should be noted when mixing quantities exceed 100g?
A: Larger mix quantities reduce pot life. For large batches, using a mechanical dispensing system with strict temperature and mixing time control is recommended.

Q3: Why is Part B's shelf life shorter than Part A's?
A: Part B (isocyanate) is more moisture-sensitive and can react with airborne humidity, hence its shorter shelf life (3 months). Reseal immediately after use and store in a dry environment.
