espol™ 30.00 is a non-accelerated isophthalic polyester resin that rapidly wets out reinforcements. It has a medium viscosity and reactivity and uses superior glycols compared to general-purpose resins, giving it good mechanical and chemical resistance. It is suitable for the fabrication of chemical tanks, industrial applications, and marine applications.

Polymer Name: Polyester (unspecified)

Chemical Family: Orthophthalics, Polyesters, Unsaturated Polyester (UPE)

Formulation Guidelines
  • espol™ 30.00 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™ 30.00 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™ 30.00 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.

Storage & Handling

Shelf Life
3 Months
Storage Conditions

espol™ 30.00 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.
