Type
Suggested use
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.
Limitations
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.
Surface preparation
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.
Application
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.
Recommended DFT
As required to wet out the glass fiber matting.
Practical coverage rate
Dependent on the type and thickness of the glassfiber utilized.
Density
Base: 0.04lbs/cubic inch (1.13 g/cm3 Hardener: .03lbs/cubic inch (1.05 g/cm3
Adhesion
>11MPa (when applied in immersed conditions and after immersion in water.)
Cathodic disbondment
Excellent 0-1mm (when used as part of a lining system)
Salt spray
>1000 hours
Mixing ratio
2:1 parts Base to Hardener by weight / weight.
Overcoating
Can be overcoated with UWT after 6hrs.
Cleaning solvent
For best results use Corrocoat Epoxy Equipment Cleaner.
Pot life
Generally, 100 minutes at 68°F (20ºC). Pot life will vary significantly with temperature.
Thinners
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.
Packaging
1 Gallon and 5 Gallon kits.
Catalyst / hardener type
Polyamidoamine (Plasmet UWL Activator)
Storage life
2 years minimum in unopened tins, stored at 40-104°F (5-40°C).
Color availability
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.
