Underwater Epoxy (River Structures, Offsho...

Korea Patent No. 10-0787646 Underwater Epoxy is the product for underwater repair and reinforcement without construction of trench wall when weirs of bridges and railway bridges crossing the river are damaged or lost by the impact of inflowing stones during the rainy season or marine structures are corroded by chloride. It is typically constructed by underwater mortar using underwater epoxy but it has a problem with cracks caused by detachment due to the difference in the coefficient of expansion. SC770S Underwater Epoxy developed to solve this is used for underwater cross-section recovery mortar process, which is the method of adding mixed sand to underwater epoxy with excellent underwater adhesion, durability, chemical resistance and water resistance and of reinforcing anti-corrosive rebar or fiberglass grating, aramid fiber grating, stainless steel wire. (Korea Patent No. 0787646) * Mixing ratio (main component: curing agent) = 2:1 Features of Product It has good liquidity, so injection into the narrow space is possible. - Injection into 30mm width of the narrow space is possible and filling mixed mortar in between latticed by rebar 50mm and 12 mm on the 50mm width is possible. Excellent underwater adhesion by the exchange of water molecules and ion SC770S Underwater Epoxy is slightly alkaline, so it does not affect the cement. - It doesn't corrode or doesn't make chemical change not to have detachment, so excellent construction is possible in repair and reinforcement. Mechanical strength is excellent and durability is good. There is no shrinkage for curing, so there are no cracks if worked at the same time. There is no separation of aggregate. - As resin is mixed with non-shrink mortar and keystone, the proportion of the keystone and cement in curing is higher and in precipitation, but this product has no precipitation, the aggregate is distributed constantly, so it has no cracks Excellent ozone-resistance, salt water resistance, chemical resistance, weatherproof, etc.. The construction period can be shortened and reinforcement and repair in less space are possible. - When building is reinforced and repaired, construction period can be shortened, repair can be done in a short period of time, construction is possible using a narrow space, so construction is possible on pillars "barrage" "tops" "dams" "movement" route of marine products "dock deck" "deck" . SC770S Underwater Epoxy is not soluble in water and so even mortar leaks during placement, it doesn't affect seafood because it is not dissolved in water. Where to Use Parking lots, warehouses and large shopping centers Factories (food, electricity, electronic, machinery, industry and power plants). Water treatment plant, drainages, swimming pool, pool waterproof Flooring materials for school classrooms, offices, laboratories How to Store Keep the lid closed completely at dry and room temperature at 20°C to be stored away from any source of moisture. Please dispose the product out of retention period chemically.
