A1: The typical curing conditions for 2-IPI with bisphenol A epoxy resins are: 80-100℃ for 2-4 hours followed by post-curing at 120-150℃ for 2-4 hours. The exact curing conditions depend on the specific epoxy resin type, formulation and desired product properties.

A2: The recommended dosage of 2-IPI ranges from 1% to 5% by weight of epoxy resin, depending on the desired curing speed, pot life and final properties. A dosage of 2-3% is most commonly used for general purpose applications.

A3: Yes, 2-IPI is highly compatible with other epoxy curing agents such as aromatic amines, anhydrides and dicyandiamide. Combining 2-IPI with other curing agents can adjust curing speed, pot life and final product properties to meet specific application requirements.

A4: 2-IPI may cause skin and eye irritation. Required PPE includes:

• Dust mask
• Safety goggles
• Chemical-resistant gloves
• Protective clothing

A5: In case of spill:

• Sweep up and collect the spilled material
• Avoid generating dust
• Place collected material in suitable closed containers for disposal
• Wash the area thoroughly with water
• Do not allow product to enter drains or waterways

A6: 2-IPI has a shelf life of 24 months when stored in tightly sealed original containers at temperatures between 5-30℃. It should be stored in a cool, dry and well-ventilated area away from direct sunlight, heat sources and incompatible materials. Keep containers tightly closed when not in use to prevent moisture absorption and contamination.
