Yapbuilt Epoxy 720

It is used as an adhesive in ensuring the adherence of old concrete to new concrete, protecting reinforcements against corrosion before repair mortar applications, bonding different materials such as concrete, stone, metal, planting sprouts on horizontal surfaces or anchoring and assembling reinforcement.

Care should be taken to ensure that the application surface is solid, dry, load-bearing, dust-free and clean, as well as on the balance. The surface should be thoroughly cleaned of any oil, grease, rust and paraffin residues that will weaken the adherence, and there should be no loose particles on the surface. Steel surfaces should be sandblasted and cleaned of rust. The edges of the broken surface should be cut as perpendicularly as possible, the rust in the reinforcement should be cleaned, and if necessary, new reinforcement should be added. If there is a stream of water on the surface, it must be drained or closed with a suitable plug.

Preparation of the Mixture: YAPBUILT© EPOXY 720 is supplied in ready-to-use sets according to the mixing ratio. Before starting the mixture, it should be ensured that the material temperatures are between (+15)-(+25)oC. The entire 1.67 kg B component should be emptied into the 3.33 kg A component and it should be ensured that there is no material left in the B component. The mixture should be mixed with a mixer of approximately 300 rpm and a suitable mixing tip for at least 3 minutes, making sure that there is no unmixed material on the edges and bottom of the package, until a homogeneous mixture is obtained.

Application: YAPBUILT© EPOXY 720 For the adherence of new concrete to old concrete, the YAPBUILT© EPOXY 720 mixture should be applied to old concrete surfaces with a brush or roller. Following this process, new concrete should be poured between 5-40 minutes, depending on the air temperature. In the manufacture of vertical anchors, holes should be drilled at a depth suitable for the project with a drill bit at least 6 mm larger than the reinforcement diameter. The drilled holes should be cleaned with a wire brush and compressed air. The prepared material must be filled into the appropriate mortar gun. The nozzle of the gun should be pulled out from the bottom of the hole and the anchor hole should be filled with enough YAPBUILT© EPOXY 720, the anchor rod of the desired size and diameter should be turned into the hole and placed

When applying YAPBUILT® EPOXY 720, the ambient and surface temperature should not be below +5oC and above +30oC. Epoxy injection processes should be performed by technically competent applicators. The operating and reaction times of resin-based systems are affected by ambient and ground temperature and relative humidity in the air. At low temperatures, the chemical reaction slows down, this increases the duration of its use and operation. High temperatures accelerate the chemical reaction, and the times mentioned above are correspondingly shortened. In order for the material to complete its cure, the ambient and surface temperature should not fall below the minimum allowable temperature. YAPBUILT® EPOXY 720 is supplied in ready-to-use kits. During the application, solvents such as solvents should not be added to the mixture. Mixing must necessarily be carried out with the help of suitable mechanical mixers. Manual mixing should not be done.

It should be stored in a clean, dry and moisture-free environment between +50C and +250C, away from direct sunlight. It must be protected against water, frost and severe weather. In short-term storage, a maximum of 3 pallets should be placed on top of each other and shipment should be made with a first-in, first-out system. In long-term storage, pallets should not be stacked on top of each other. Provided that the specified storage conditions are complied with, the storage life is a maximum of 12 months from the date of manufacture
