Epoxy putty refers to a group of room-temperature-hardening substances used as space-filling adhesives. Exact compositions vary according to manufacturer and application. They are stored until use as two components of clay-like consistency. Kneading the two components into each other creates an exothermic chemical reaction that activates the substance for use by catalyzing an epoxide polymerisation reaction. Unlike many other types of glues, an epoxy adhesive can fill gaps and even be molded into a structural part. Some makers claim in advertising that one can drill and tap their cured products, and that they quickly cure "hard as steel" (as measured by Shore rating), though they are much weaker than steel in tensile strength and shear strength.
Multilayer composite wear-resistant epoxy floor coating
The utility model relates to the technical field of flat floor technology discloses a multilayer composite wear -resisting type epoxy flat floor, including base layer, the top fixedly connected with high permeability epoxy primer for reinforcing of base layer, the top fixedly connected with wear -resisting core layer for compression resistance of high permeability epoxy primer, the multilayer composite wear -resisting type epoxy flat floor is set up cooperation through base layer, high permeability epoxy primer, wear -resisting core layer and epoxy putty closed layer, and the setting of base layer provides the basis for coating adhesion, through the setting of high permeability epoxy primer, play the role of permeation reinforcement base surface, close matrix capillary hole to promote the adhesion, can make the reinforcement degree of base surface higher, through the setting of wear -resisting core layer, play the role of compression resistance, impact resistance and heavy load resistance, can bear higher mechanical wear, through the setting of epoxy putty closed layer, play the role of closed mortar layer pore, provide smooth delicate base surface to enhance the adhesion of finish.

An acrylic polyurethane / silane composite protective coating, its preparation method and application in concrete surface protection
The application discloses an acrylic polyurethane / silane composite protective coating and a preparation method and application thereof in concrete surface protection, and belongs to the technical field of building coatings. The protective coating is used on the concrete surface and comprises, from bottom to top, an epoxy putty layer, a modified silane impregnated intermediate layer and a modified acrylic polyurethane top coating layer. The raw material components of the modified silane impregnated intermediate layer include, in terms of mass parts, 35-45 parts of a silane impregnating agent, 0-5 parts of nano-silicon dioxide, 0-5 parts of silica sol, 0-5 parts of ethyl silicate and 0-5 parts of polyurea. The sum of the amounts of the nano-silicon dioxide, the silica sol, the ethyl silicate and the polyurea is greater than 0. The application combines the material properties of the acrylic polyurethane, the silane impregnating agent and the nano-silicon dioxide, and plays the component synergistic coupling effect, so that the protective surface coating with the functions of damage repair and reinforcement, good durability, hydrophobic self-cleaning and the like is obtained.
