Reversol P-980 P is a thixotropic, ISO - NPG, pre-promoted unsaturated polyester gelcoat resin with excellent durability and water resistance, specially developed for use in tropical climates. It is designed for use in sanitary ware and for chemical plant process fabrication, but is equally suitable for other mouldings where good resistance to water and chemicals is important. It contains UV-absorber for resistant enhancement against ultra-violet / sunlight degradation. Reversol P-980 P is supplied as a non-pigmented solution in styrene monomer and formulated to be applied by spray. For brush application, Reversol P-960 should be used.

Application Advice/Typical Applications

(# Curing schedule was 12 hrs at 25ºC followed by 12hr 50ºC and 3 hrs at 80ºC except for HDT where schedule was 12 hrs 25ºC followed by 3hr 50ºC, 3 hrs 80 and 3 hrs at 120ºC) Reversol P-980 P is compatible with most unsaturated-resin base color paste.

Application method : Spray Recommended catalyst level : 1.5 – 2.0% Recommended film thickness (wet) Moulding making : 0.80 – 1.00 mm (0.030-0.047 inches) FRP parts : 0.50 – 1.00 mm (0.020-0.040 inches) As a guide 600-1000 g/m2 wet gelcoat should furnish above gelcoat thickness for FRP parts.

Shipping and Storage

To ensure maximum stability and to maintain optimum resin properties, Reversol P-980 P should be stored in close containers below 32ºC 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-980 P will remain stable for 3 months from date of delivery.
