espol™ 27.01 should be stored between 5°C and 25°C in the original, unopened container in a dry, well ventilated place. Protect from freezing and direct sunlight. Avoid contact with oxidizing agents. If stored outside of these recommendations, shelf life will be significantly reduced.
- Formulation Guidelines
- espol™ 27.01 should be allowed to attain workshop temperature (25°C - 30°C) before use. Stir well by hand, or with a low shear mixer to avoid aeration, and then allow to stand to regain thixotropy. espol™ 27.01 requires only the addition of catalyst to start the curing reaction in elevated temperature cure processes.
- The recommended elevated temperature curing catalyst is TBPB which should be added to the resin at 1 - 2% and thoroughly incorporated into the resin, using a low shear mechanical stirrer where possible.

Technical Details & Test Data
- Post Curing
Satisfactory laminates for many applications can be made from espol™ 27.01 by curing at workshop temperature (25°C). For optimum properties, however, laminates should be post-cured before being put into service. The laminate should be allowed to cure for 24 hours at 25°C, and then be oven cured for a minimum of 6 hours 80°C.
