Applications: espol™ 31.00 is designed for hand laminating, spray up & casting applications. espol™ 31.00 offers chemicals resistance towards most mineral and organic acids, solvents and oils making espol™ 31.00 an ideal choice for making glass reinforced chemical process equipment, fabrication of Bridge Supports, ladders and components exposed to sewerage & effluents.
Formulation Guidelines: espol™ 31.00 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™ 31.00 requires the addition of accelerator and catalyst to start the curing reaction.

The recommended accelerator is Cobalt (1% solution in styrene) which should be added to the resin at 1 - 2% and thoroughly incorporated into the resin, using a low shear mechanical stirrer where possible.

The recommended catalyst is MEKP (50%) which should be added to the resin at 1 - 2% and thoroughly incorporated into the resin, using a low shear mechanical stirrer where possible.

N.B. Catalyst and accelerator must not be mixed directly together since they can react with explosive violence.

Technical Details & Test Data

Post Curing: Satisfactory laminates for many applications can be made from espol™ 31.00 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.

Packaging & Availability

Packaging Type: Totes (IBC)
Packaging Information: espol™ 31.00 is available in 35kg, 225kg and bulk containers.

Storage & Handling

Shelf Life: 3 Months
Storage Conditions: espol™ 31.00 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.
