Reversol P-9509 NW is a variant of Reversol P-9509. It is a non-wax, low reactivity and thixotropic general purpose resin. It is a preaccelerated resin for ambient temperature gel and cure with addition of Methyl Ethyl Ketone Peroxide (MEKP) as catalyst. The resin has outstanding wetting of glass fibre and easy air release during roll down. It is suitable for spray-up and hand lay-up applications. Gel, cure and demoulding time are sensitive and dependent on catalyst used as well as temperature of environment. Generally, use more catalyst on a cold/rainy environment and lesser catalyst on a hot day.

Application Advice/Typical Applications

Catalysation with 1% MEKP would render resin suitable for general purpose FRP lamination application viz : FRP tank and panel FRP boat fabrication.

Shipping and Storage

To ensure maximum stability and maintain optimum resin properties, Reversol P-9509 NW 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-9509 NW will remain stable for 3 months from date of delivery.
