REVERSOL P-9565

Reversol P-9565 is a versatile, low viscosity orthophthalic unsaturated polyester resin designed for RTM and can also be used in other resin injection or vacuum assisted techniques. It is also suitable for closed mould techniques such as cold press or Prestovac. Reversol P-9565 is supplied as non-promoted and non-thixotropic. This resin can be cured using cobalt promoter with either Methyl Ethyl Ketone Peroxide or Acetyl Acetone Peroxide (AAP) as catalyst. However, AAP is selected for most application since it gives a faster mould turn around. An even more efficient cure can be obtained by using Acetyl Acetone Peroxide-Butyl Peroxybenzoate mixture; this catalyst is specifically developed for RTM applications.

Application Advice/Typical Applications

(# Curing schedule - 24 hrs at 20°C and 16hrs 40°C. * Curing schedule - 24 hrs at 20°C and 3 hrs at 80°C except for HDT which was post cured at 24 hrs 20°C , 5 hrs 80°C and 3 hrs at 120°C)

Shipping and Storage

To ensure maximum stability and maintain optimum resin properties, Reversol P-9565 should be stored in closed containers 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 and used on a first-in-first-out basis. When properly stored, Reversol P-9565 will remain stable for 3 months from date of delivery.
