Water glue is the general name of glue with water as solvent or dispersion medium, compared with the usual solvent glue (i.e. glue with organic solvent as solvent or dispersion medium). It is liquid at room temperature and can be divided into single component and multi-component. After curing, it is generally irreversible. For single component adhesives, some are only after the water volatilizes, and the adhesive solidifies to form bonding, which is a physical process; In some cases, with the volatilization of water, the active groups in the adhesive molecules react to form bonding, and chemical and physical processes coexist. For two-component glue, the curing is mainly chemical process, accompanied by physical process.
Water glue is mainly used for surface bonding with good bonding strength. It can be cured under normal or medium temperature conditions. It has the characteristics of small curing shrinkage, yellowing resistance, colorless and transparent. It is an environmental protection chemical. Suitable for small and medium-sized craft equipment. It is widely used in the bonding of plastics, rubber, fiber, stone, metal, wood, other materials, ceramics, paper, etc. It is characterized by natural flat and fast, easy to remove bubbles, not easy to overflow glue, less man hour loss and high yield. When storing, keep away from heat source and in a cool place.
