Isothalic Resin
Chemical Name:
Isothalic Polyester Resin

Detailed Product Description:

#90 Isothalic Polyester Laminating Resin features greater toughness, impact

strength, and flexibility than the more common orthothalic polyester laminating


It is a good choice for detailed molds requiring greater dimensional stability,

corrosive service part fabrication, and as a durable repair material for tank

linings. It permits fast wet-out in spray or hand laminates.

Isothalic polyester resins have a 225˚F service temperature so they resist the

effects of the curing exothermic reaction and many post-cure problems.

Properly fabricated parts may be used in food contact applications.
