Case description

Aerospace industry: aircraft metal parts, aluminum alloy wings, tail and other widely used adhesive bonding, using varieties of phenolic urea formaldehyde, epoxy-phenolic, butyronitrile-phenolic, nylon - epoxy adhesives, among which 120℃ curing epoxy - butyronitrile modified glue is the mainstream;
Adhesive also known as adhesive, commonly known as "glue". It is a substance that connects two materials together through the adhesion and cohesion strength of the interface, without significant changes to the structure of the bonded material, and endowing the bonding surface with sufficient strength. The bonding of the interface overcomes the phenomenon of stress concentration during welding or riveting with adhesives. The bonding has good vibration resistance, fatigue resistance, uniform stress distribution, good sealing and so on. Adhesives can replace welding, riveting, bolts and other mechanical connections in many fields. They are suitable for the bonding of special-shaped and complex components, as well as for the bonding of sheet materials and small components. In aerospace, transportation, instrumentation, electronic appliances, textile, construction, wood processing, medical instruments, machinery manufacturing, daily necessities and other fields of adhesive and bonding technology has been widely used.
