Reversol P-880 P is a thixotropic, isophthalic, promoted unsaturated polyester gelcoat with excellent durability and water resistance, specially developed for use in tropical climate. It is designed for boat hulls which are to remain immersed for long periods in water, but is equally suitable for other mouldings where good resistance to water and chemicals is important. Reversol P-880 P is supplied as a non-pigmented solution in styrene monomer and formulated to be applied by spraying (For brush application, Reversol P-860 P should be used). Where Reversol P-880 P is used on laminated surface, excellent resistance to weathering can be obtained.

Application Advice/Typical Applications

(# Curing schedule was 24 hrs at 20°C followed by 3 hrs at 80°C except for Deflection Temperature where schedule was 24 hrs 20°C followed by 5 hrs 80°C and 3 hrs at 120°C)

Application method : Spray Recommended catalyst level : 1.5 – 2.0 % pbw Recommended film thickness (wet) : Mould making : 0.80 – 1.20 mm (0.03-0.047 inches) FRP parts : 0.50 – 1.00 mm (0.02-0.04 inches) As a guide 600-800 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-880 P should be stored in close 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-880 P will remain stable for 3 months from date of delivery.
