Reversol P-9780 is a non-promoted nonthixotropic high heat resistant isophthalic based polyester resin developed to meet the exacting thermal and electrical requirements of the aircraft industry, but is equally suitable for use in other high performance applications where high strength reinforcements such as glass cloth or woven rovings should be used. This resin can be applied by brush or spray equipment and may also be used in the pultrusion process for the production of profile sections. When fully cured and post cured, Reversol P-9780 is resistant to fuel oils and similar chemicals . Fully cured laminates made from Reversol P- 9780 can be exposed for long periods to temperatures up to 150°C, and for shorter periods (several hours) to temperature up to 200°C.

Application Advice/Typical Applications

(# Curing schedule was 12 hr at 25°C followed by 12hr at 50°C and 3 hr at 80°C, except in determining deflection temperature, where the schedule was 12 hr at 25°C, 12 hr at 50°C, 3 hr at 120°C)

High performance FRP laminates tanks and containers. Pultrusion of profile sections. Glass Flake coating

Shipping and Storage

To ensure maximum stability and maintain optimum resin properties, Reversol P-9780 should be stored in close containers maintained below 32°C and away from heat sources and sunlight. All storage should conform to local fire and building codes. Drums should be stored away from all sources of flame or combustion. Inventory should be maintained at minimum reasonable stock level on first-in-first-out basis. When properly stored, Reversol P-9780 will remain stable for 3 months from date of delivery.
