Calculate and verify the resin-to-hardener ratio before preparing each batch.
Mix ARADUR 3277 thoroughly with the selected epoxy resin until the material is completely uniform.
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 the mixed formulation within its validated pot life.
Consider the effects 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.
Use the current Huntsman technical data sheet and regional safety data sheet as the controlling documents for formulation, transport, storage, exposure control, first aid, and emergency response.
