Handling Precautions:
Confirm the correct resin-to-hardener ratio before preparing each batch.
Mix ARADUR 3253-1 thoroughly with the selected epoxy resin until a completely uniform blend is obtained.
Scrape the sides and bottom of the mixing container to prevent unmixed material.
Avoid preparing unnecessarily large batches because the curing reaction may generate substantial heat.
Do not seal containers containing freshly mixed resin and hardener.
Use mixed material within the validated working time of the complete formulation.
Account for the effect of ambient temperature, substrate temperature, and mixed mass on curing speed.
Apply the formulation only to clean, dry, and properly prepared substrates.
Keep emergency eyewash stations and safety showers readily accessible.
Follow the current Huntsman technical data sheet and regional safety data sheet for formulation, storage, transport, exposure control, first aid, and emergency response.
