Valid from: 5th July 2018
Last reviewed: July 2019
Type: An epoxy laminate, intended for application with glass fiber matting designed to be applied and cure underwater, as part of an underwaterrepair system.
Plasmet UWL is designed for use with Plasmet UWP and Plasmet UWT as an underwater repair system. It will provide cost effective, durable protection on sub-merged surfaces. The system is tolerant of water and will cure while immersed. It may be used for structural steel, pilings, jetties, and other immersed structures.
Immersed Temperature limit is 113°F (45ºC) as a system.
Health & safety
Before handling or using this product the safety data sheetshould be read and all precautions observed.
Metals: Corrocoat UWL is generally applied over mechanically prepared or water-blasted surfaces. For best results Plasmet UWL should be applied over a surface primed with Plasmet UWP.
Thoroughly wet out the glass fiber cloth above water. The glass fiber cloth can now be transported to the application site. One method of doing so is for the laminate to be applied onto a thin Perspex sheet. This can then be rolled into a tube, unrolled underwater and applied to the UWP using a glassfiber matting roller.
As required to wet out the glass fiber matting.
Practical coverage rate
Dependent on the type and thickness of the glassfiber utilized.
Base: 0.04lbs/cubic inch (1.13 g/cm3 Hardener: .03lbs/cubic inch (1.05 g/cm3
>11MPa (when applied in immersed conditions and after immersion in water.)
Excellent 0-1mm (when used as part of a lining system)
2:1 parts Base to Hardener by weight / weight.
Can be overcoated with UWT after 6hrs.
For best results use Corrocoat Epoxy Equipment Cleaner.
Generally, 100 minutes at 68°F (20ºC). Pot life will vary significantly with temperature.
The performance of this product will be adversely affected by the use of solvent-based thinners. Under normal application conditions it is not anticipated that any thinners will be required with this product.
1 Gallon and 5 Gallon kits.
Catalyst / hardener type
Polyamidoamine (Plasmet UWL Activator)
2 years minimum in unopened tins, stored at 40-104°F (5-40°C).
Mid Grey. The Base (white) and Hardener (black) should be mixed until a uniform grey color is achieved.NOTE:This product is formulated to give optimum corrosion resistance. Due to the nature of the polymerization process on this product and the speed of immersion, it is not possible to guarantee color matching or color stability.Some whitening of the surface may occur during the curing process.
