Elastic paint is made of high-elastic synthetic resin emulsion. It is a functional exterior wall coating that prevents fine cracks on the surface of the building and prevents wall leakage. It can also be called elastic architectural coating.
Main film-forming substances:
The main film-forming material of the elastic exterior latex paint is an elastic polyacrylic synthetic resin emulsion, which functions to bond other components in the coating into a whole. When the coating is dried and hardened, it can adhere to the surface of the coated substrate to form a uniform continuous and tough elastic protective film. The elasticity of the coating film is mainly determined by the structure and composition of the elastic polyacrylic resin. The macromolecule of this resin is highly curled, and the molecular smell is weak, and it is easily deformed under the action of external force. The deformation disappears after the external force is removed, and thus exhibits elasticity. Usually, the emulsion is self-crosslinking and thus has good stain resistance, and is an ideal base for elastic exterior latex paints.
Pigment filler
Pigments and fillers not only can make the coating have a certain hiding power, but also can display a certain color, and can also enhance the strength of the coating itself, pigments, fillers and prevent UV penetration. The aging resistance and weather resistance of the coating can be improved.
water
In aqueous liquid architectural coatings, water is a dispersion medium. After the coating is applied to the substrate, the coating is gradually dried and hardened by evaporation of water. Finally, a uniform continuous elastic coating film is formed.
Flexible architectural coating
Due to the high elasticity of the elastic exterior wall paint film, when the wall has cracks, the film is stretched and deformed without cracking, and the intact film still maintains various barrier functions to prevent cracking. The wall is directly exposed to the atmosphere. The elastic paint film has barrier properties against various substances (water and other liquids, etc.), prevents intrusion of various corrosive substances into the interior of the wall, thereby effectively protecting the wall from damage and giving full play to its protective function.
Synthetic Resin Emulsion Elastic architectural paint film also has a certain permeability when it is waterproof and impervious. That is, the fine pores of the elastic architectural coating can allow a small amount of water vapor to enter and exit, and the water droplets with larger particle diameters are difficult to pass, thereby achieving the waterproof and breathable effect. The global paint network understands that a good elastic paint can also effectively prevent carbon dioxide from penetrating into the base layer through the paint film, thereby preventing the carbonization of the wall concrete.
Compared with other exterior architectural coatings whose main function is decorative function, the flexible building is characterized by the decorative function and the protection function. In this way, the use of high-quality elastic exterior wall paint can prevent wall leakage and ensure the normal function of the building while doing wall decoration.
Polyurethane elastomer coating
Since the 1990s, polyurethane elastomer coatings (especially polyurethane-polyurethane polyurea blend elastomers) have been widely used in industry. For example, the outer coating of the aircraft is mostly PU. You can touch it before you get into the door next time, and experience the tough and elastic touch. Polyurethane elastomeric coatings can be well combined with materials such as metal and concrete. If they are sprayed thick enough, they are equivalent to wearing a layer of elastic outerwear that can be used to greatly improve the brittleness of these materials.
If you have a car, you are likely to pass the polyurethane elastomer in a 4S shop or auto repair shop. In those places, its name is: chassis armor. Spraying this layer of this material on the chassis can reduce the damage caused by bumping of the chassis and reduce rust. But if you sit on a leather sofa in the summer, you will understand that the chassis armor will also affect the car's heat dissipation.
In the United States, the number of small trucks such as pickup trucks is high, and many owners will choose to spray a layer of polyurethane elastic paint on their cars to reduce the bump and wear of the goods on the car body. In the United States, this is called BEDLINER. Through their violent assessment, this coating can indeed reduce the damage caused by minor collisions and explosive fragments, and can significantly reduce the dog's damage to the car, including grasping, licking and urine. . Of course, this will cost the car a lot of weight and heat.

A treadmill is an exercise machine for running or walking while staying in one place. The word treadmill traditionally refers to a type of mill which was operated by a person or animal treading steps of a wheel to grind grain (see treadwheel.)
The machine provides a moving platform with a wide Conveyor belt and an electric motor or a flywheel. The belt moves to the rear allowing a person to walk or run an equal, and necessarily opposite, speed. The rate at which the belt moves is the rate of walking or running. Thus, the speed of running may be controlled and measured. The more expensive, heavy-duty versions are motor-driven. The simpler, lighter, and less expensive versions passively resist the motion, moving only when the walker pushes the belt with their feet.
