Wencon UW Coating
Wencon UW Coating is two-component solvent free liquid coating, for protection against corrosion and bi-metallic corrosion, erosion as well as impingement. The coating can be applied under water.
Wencon UW (underwater) Coating is a two component product, to be applied on wet surfaces or under water. The UW Coating is ideal for repair of ballast- and cooling pipes, combined with interchanging layers of Wencon reinforcement tape. Excellent for repair jobs which, due to high humidity, have to be done in wet conditions.
Typical applications are coatings of steel surfaces rebuilt with Wencon UW Cream, and coatings under water – like ships hulls and/or other submerged structures, tanks, pipes etc. Examples of repairs under extreme conditions could be: On-site repair of sea-water filter housings, unable to achieve a dry surface and coating of scratched painting on hulls in splash-zones and under water.
- Can be applied on wet surfaces or under water
- Cures under water and on wet surfaces
- Efficient double coat system
- Long pot-life under water
- Strong adhesion to all metal and GRE surfaces

Wencon UW Coating
The Wencon UW Coating is a two-component product, to be applied on wet surfaces or under water. The UW Coating is ideal for repair of ballast- and cooling pipes, in connecton with Wencon reinforcement tape. Developed for repair jobs which, due to high humidity, have to be done in wet conditions.
After curing, Wencon UW Coating will provide a smooth, nonporous coating, which is resistant to bi-metallic corrosion, light chemical attack, corrosion and impingement. Wencon UW Coating contains no solvents.
Wencon UW Coating is a double coat system and is consequently supplied in two different colors, orange and brown.
APPLICATION AREAS
Typical applications are coatings of steel surfaces rebuild with Wencon UW Cream, and coatings under water - like ships hulls and/ or other submerged structures, tanks, pipes etc. Examples of repairs under extreme conditions could be: on-site repair of sea-water filter housings etc. unable to achieve a dry surface. The UW Coating is also used for scratched painting on hulls in splash-zones and under water.
MIXING
Wencon UW Coating has to be mixed above water in the mixing ratio 1:2 by volume.
GENERAL DESCRIPTION
Two-component solvent free liquid coating, for protection against corrosion and bi-me- tallic corrosion, erosion as well as impingement. The coating can be applied under water.
SURFACE PREPARATION
When Wencon UW coating is applied on top of Wencon UW Cream, it has to be applied when the layer of UW Cream is still tacky.
When applying to an old steel surface under water, the surface must be cleaned for loose paint, scales, under water growth, etc. A mechanical cleaning will do, if possible, use hydro-jetting for the best result.
MIXING RATIO
Mix by volume 1:2. Mix until an even color is obtained. The mixing has to take place above water. After mixing, the product can be taken into the water.
POT LIFE
Depending on amount mixed and the temperature. Mixed in small amounts, the pot life is approximately 25-35 minutes at 20°C. (68°F)
APPLYING
Wencon UW Coating is applied using a spatula, brush or roller. If the temperature is low – use a brush with short bristles. If the temperature is high, use brush with long
bristles. The initial wetting of the brush/roller has to take place above water.
OVERCOATING
Wencon UW Coating is a double coat system. The overcoating time can vary from one to three hours, depending on the temperature.
The second layer has to be applied while the first layer is still tacky. The time will vary from 2-6 hours.
CURING TIME
Curing will take place in 10-18 hours, but only if the temperature allows it to cure. Curing requires a temperature of at least 10°C (50°F), but better at 17-23°C (62-73°F)
or higher.
If the coating shall be exposed to chemicals, let it cure for 7 days before exposure.
Reduced curing time with infrared.
This product is tested with and suitable for infrared curing. Curing with infrared radiation can reduce curing time significantly. Result can vary, depending on circumstances and equipment used.
MACHINABILITY
After curing, the product can be machined, drilled and worked like metal.
Coverage rate
Approximately 0,8 sq. m. per kg per coat. (0,4 lb/sq. ft)
