psi). Typical applications are high- abrasive or corrosive situations suffering excessive wear, such as propellers and nozzles, impellor housings, pump housings, rudders, thruster tunnels and housings.
Wencon 1050/1060 Hi Temp is a high-performance two-component, liquid epoxy coating for repair and protection in high temperature, chemically and mechanically aggressive environments. Developed for the Marine, Off-shore and Industrial sectors, It provides a very strong (Hardness D Shore 82, Tensile strength 13.8 N/
sq.mm. [2,001 psi]), smooth, non-porous finish, resistant to acids, alkalis and solvents. The adhesion to steel is 22.4 N/
sq.mm. [3,248 psi]. The HiTemp is machinable, and cures between 10-24 hours at 20ºC, which can be reduced significantly using Infrared radiation. Typical applications are hot pipes, protection of tanks, pumps, valves against chemical and mechanical corrosion, erosion, cavitation and bi-metallic corrosion.
And now the specialist products...
Wencon 1070 Exhaust Repair Kit is a very important, very specialised, single component, very high temperature resistant, cold weld repair. 1070 Exhaust Repair resists direct flame, and temperatures of up to 1,300ºC, excellent for repairs to cracks and holes in exhaust manifolds, pipes, engine blocks, furnaces and boilers and other high temperature applications. This product sets within 4 hours at ambient temperature or quicker if heated; 15 minutes at 95ºC for example. Due to its strength and hardness, this product is very difficult to machine, although it is possible to grind to shape. The 1070 Exhaust Repair Kit contains two 250 gram containers of Exhaust Repair, and a metal reinforcement mesh. All-in-all a practical and very effective emergency repair product to hold in the engine room.

Wencon 1014 UW Cream Repair and 1035 UW Coating are Rebuild and Protection products for use underwater, or on wet substrates and in humid conditions. The two-component 1014 UW Cream Repair, is a durable repair product, Hardness Shore D 79 (DIN 53505), and Tensile strength 35.8 N/
sq.mm.with (5,191 psi) with an extremely strong bond (e.g. Steel 33N/
sq.mm, [4,785 psi] adhesion), and Compressive strength 2,631 N/
sq.mm. (381,495 psi). These products have been developed for use where it is not possible to apply on a dry surface, both Coating and Cream Repair provide a smooth, non-porous, finish, resistant to corrosion, erosion and bi-metallic corrosion, also water, sea water, oil and light chemical attack.
All underwater products should be mixed out of the water, have a very practical 30 minute pot-life, with 10-18 hours cure-time at an advised minimum of 10ºC. Curing time can be decreased significantly using Infrared radiation. Excellent repair and protection solutions for any corroded submerged metalwork, they are non-conducting, do not corrode or erode, and are temperature resistant to 160ºC as

Pipetape is a strong (Tensile strength 172 N/
sq.mm. [24,940 psi]) pre-impregnated, water activated bandage, especially formulated to make fast repairs on leaking pipework carrying water, steam, oil, gases or solvents. The bandage is knitted rather than woven allowing maximum strength (Compression strength 180 N/
sq.mm [26,100 psi]) to the repair, with Adhesion to steel 19 N/
sq.mm. (2,755 psi). The repair is resistant to 120ºC, or temporary peaks of 190ºC, and pressure resistant to 10 Bar, 50 Bar if reinforced with 1042 Wencon Putty Repair when held in place using the Pipetape.
To apply, the bandage roll is taken out of the container and soaked in water for ten seconds. After wrapping the bandage around the leak, the pipe is normally ready for use after ten minutes and the repair cured after 60 minutes.
