Two-component adhesive (epoxy, polyurethane)
Two-component adhesive - a group of high-qualityadhesives, which do not contain solvents. The main constituents are resins (binders) and hardeners (separately stored, can be in suspension or in powder form).
As a result of the chemical reaction beginningafter mixing these two components, the composition hardens, acquiring after a few minutes the initial bonding strength. The speed of curing depends largely on the temperature and quality of pre-stripping. The final strength is dialed after a few more hours.
Adhesive epoxy bicomponent is prepared clearlyaccording to the instructions, in accordance with the proportions indicated in it and the holding time. When gluing two parts, you can apply the activator to one part, and the resin to the other. When connected, the components are contacted as described above.
The main field of application of epoxy glueare non-porous materials (all but synthetic ones) that need to be glued securely. For greater strength, the resin can be reinforced with fiberglass. Such a method allows solving complex problems that arise, for example, when repairing machines. Sometimes a high proportion of metal powder is added to the two-component glue and used as cold welding. The parts thus connected have an increased strength.
To particularly strong and reliable is andtwo-component polyurethane adhesive, used in virtually any area. It perfectly glues leather blanks with a sole, wooden elements (including heavy ones), aluminum, glass, metal structures, natural stone. This two-component glue is not afraid of dampness, so it is suitable for construction in rooms with high humidity (for example, in the bathroom, in a bath, etc.). It is ideal for work related to the laying of tiles (including for laying out drawings and mosaics), for gluing joinery products, for finishing facades with stone.
Thanks to polyurethane glue, laying the system"Warm floors" saves not only time, but also money and strength. Regardless of the type of flooring, after eight hours you can not only walk on it, but also arrange furniture. This glue (unlike analogues) is almost not elastic, and therefore does not shrink and does not stretch. These qualities are maintained even under very heavy loads.
It is reliability that is one of the mainselection criteria for shoe factories and small shoe shops. Regardless of the structure of the sole (PVC, porous, etc.), the polyurethane glue shoe grips the surfaces so firmly that it is simply impossible to break them after drying. Such footwear is not afraid of rains, gives ease, comfort and pleasure.
Two-component adhesives (polyurethane,epoxy) are particularly strong and durable, perfectly fix the details, joints, joints and confidently replace the analogues. They are used in almost all types of work, regardless of the level of complexity. Ceramics, tiles, bricks grasp "to death", which is why those who have used two-component glue, choose it again.
