Wencon UW Putty
Wencon UW Putty is a two-component compound, that can be applied on wet surfaces or underwater. The UW Putty is excellent for filling up holes, dents, and rebuilding surfaces which, due to high humidity, have to be done in wet conditions. Wencon UW Putty is developed for applications, where bigger quantities are needed in one process.
Typical applications are corroded hulls and all underwater parts of vessels and structures, tanks, pipes, flange faces, etc. Wencon UW Putty is also suitable for filling gaps and holes underwater or on wet surfaces, before completion with Wencon UW Cream or UW Coating.
- Can be applied on wet surfaces or underwater
- Cures underwater and on wet surfaces
- Stop leaking pipes and tanks
- Long pot-life underwater
- Strong adhesion to all metal surfaces

Wencon UW Putty
Wencon UW Putty is a two-component compound to be applied on wet surfaces or under water. The UW Putty is excellent for filling up holes, dents and rebuilding of surfaces which, due to high humidity, have to be done in wet conditions. Wencon UW Putty is developed for applications, where bigger quantities are needed in one process.
After curing Wencon UW Putty shares many of the same characteristics of metals, which together with outstanding adhesion to all metallic surfaces, makes the compound highly suitable for repair of corroded and worn metal.
Wencon UW Putty is nonconductive and will therefore not cause bi-metallic corrosion. After curing Wencon UW Putty is resistant to oil, salt water, most diluted acids and a range of solvents.
APPLICATION AREAS
Typical applications are corroded hulls and all underwater parts of vessels and structures, tanks, pipes, flange faces, etc. Wencon UW Putty is also suitable for filling gaps and holes under water or on wet surfaces, before completion with Wencon UW Cream or UW Coating.
MIXING
Wencon UW Putty has to be mixed above water in the mixing ratio 1:1 by volume.
GENERAL DESCRIPTION
Two-component solvent free pasty consistency epoxy repair compound, for applying under water or on wet surfaces.
SURFACE PREPARATION
Before applying, the surface must be clean from loose paint, scales, under water growth, etc. A mechanical cleaning will do, but even better, if possible, hydro jetting.
APPLYING
Mix the product 1:1 on a mixing plate. Then continue in your hands, wearing wet protection gloves. Mix until the product has an even color without any “stripes” and press/ rub the UW Putty hard against the surface, by hand or by using a spatula.
POT LIFE
Depending on amount mixed and the temperature. Mixed in small amounts, the pot life is approximately 25 minutes at 20°C (68°F)
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.
MACHINABLE
After curing, the product can be machined, drilled and worked like metal.
