Product reference: 5/91
Product title: PlasmetUWT
Valid from: 5th July 2018
Last reviewed: July 2019
Type
An epoxy glass flake topcoat, intended for application and cure underwater
as part of an underwater lining system.
Suggested use
Plasmet UWT is designed for use with Plasmet UWPand
Plasmet UWL as a system. It will provide cost effective,
durable protection to submerged 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 sheet
should be read and all precautions observed.
Surface preparation
Corrocoat UWT is applied over UWL. No additional surface
preparation required.
Application
CorrocoatUWT may be applied by trowel or divers glove in a
single coat.
Pot life
Generally 60-70 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 UWT Activator)
Storage life
2 years minimum in unopened tins, stored at 40-104°F (5-
40°C).
Cleaning solvent
For best results use Corrocoat Epoxy Equipment Cleaner.
Color availability
Light Grey.
TheBase (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.
Recommended DFT
Apply at 12-20 mils (300-500 microns).
Theoretical coverage rate
100sf per gal at 16 mils (2.5m2 /L at 400 microns).
NOTE: This information is given in good faith but consumption may increase dependent upon the Environmental conditions, geometry,nature of
work undertaken and the skill and care of application.
Corrocoat accepts no responsibility for any deviation from these values
