Adhesives are organic or inorganic, natural or synthetic substances of the same or two or more homogeneous or heterogeneous parts (or materials) that can be joined together and have sufficient strength after curing, also known as adhesives, binders, customarily referred to as glue.
Commonly used adhesives are synthetic adhesives. Synthetic adhesives are composed of main agent and auxiliaries, also known as the main material, base material or adhesive; auxiliaries are curing agents, diluents, plasticizers, fillers, coupling agents, initiators, thickeners, antioxidants, inhibitors, stabilizers, complexing agents, emulsifiers, etc., according to the requirements and uses can also include flame retardants, foaming agents, defoamers, colouring agents and mould inhibitors and other components.
According to incomplete statistics, more than 6000 kinds of adhesive products have been introduced so far, because it can realize the connection of the same or different materials, no stress concentration in the joint part, high bonding strength, easy to realize the automation of chemical operation, etc., widely used in various fields in the national economy. At present, the production and sales scale of the adhesive industry continues to grow rapidly, the technical level of adhesives continues to improve, a large number of domestic and foreign advanced level products continue to emerge, adhesives to modified, reactive, multi-functional, nano-type and other directions of development, application areas also to new energy, energy saving and environmental protection and other emerging industries focus.
NOA has nearly 30,000 square meters of central laboratory, with organic laboratory, inorganic laboratory, physical and chemical laboratory, thermal analysis laboratory, mechanics laboratory, reliability laboratory, combustion laboratory, weather resistance laboratory. It can provide one-stop analysis and testing services for adhesive products such as raw material quality control, composition analysis, foreign substance analysis, performance testing, environmental performance and reliability testing.
