Adhesive manufacturers share adhesive bonding technology – adhesive formula and types
Adhesives play an important role in industry and daily life, with a wide variety of types and applications. There are numerous adhesive brands emerging in the market, with each manufacturer offering various types and prices of adhesives. Adhesive, also known as adhesive or bonding agent, is commonly referred to as glue.
There are various types of adhesives, which can be classified according to their application methods as thermosetting, hot-melt, room temperature curing, pressure-sensitive, etc; According to the application object, it can be divided into structural, non structural, or special adhesives. Structural adhesives include thermosetting adhesives such as epoxy resin, polyurethane, organosilicon, polyimide, as well as thermoplastic adhesives such as polyacrylate, polymethacrylate, methanol, and multi-component adhesives such as phenolic epoxy modified adhesives. Adhesives can be divided into solvent volatilization type, lotion type, reaction type and hot-melt type according to the curing form; According to the formula, it can be divided into organic and inorganic categories. In addition, according to appearance classification, it can be divided into three categories: liquid, paste, and solid; Classified by components, it can be divided into single component, two-component, and reactive types. Common types of adhesives include AB structural adhesive, fast drying adhesive, anaerobic adhesive, etc; According to their applications, they can be divided into metal adhesives, screw adhesives, plastic adhesives, carbon fiber adhesives, rubber elastomer adhesives, etc.
The formula composition of adhesive mainly consists of main agent and auxiliary agent. The main agent is also known as the main material, base material, or binder, while the auxiliary agents include curing agents, diluents, plasticizers, fillers, coupling agents, initiators, thickeners, anti-aging agents, polymerization inhibitors, stabilizers, complexing agents, emulsifiers, etc. According to requirements and applications, adhesives can also include components such as flame retardants, foaming agents, defoamers, coloring agents, and mold inhibitors.
Adhesives have a wide range of applications. Quick bonding products can use instant adhesives, without the need for heating and pressure, and have the characteristics of fast curing and high bonding strength. The bonding of structural components involves buildings, vehicles, ships, aircraft, spacecraft, etc., which require a long period of load and high stress, and adhesives play a key role. Liquid sealing and plugging adhesive can replace traditional gaskets, and the common sealing adhesive is anaerobic adhesive. In addition, adhesives can also be used in underwater bonding, oil surface bonding, hot melt bonding, high temperature resistant bonding and ultra-low temperature bonding, pressure-sensitive bonding, medical bonding and other fields.
The characteristics of adhesive technology shared by adhesive manufacturers lie in how to correctly use adhesives to ensure good bonding effects. In addition to selecting the appropriate adhesive, it is also necessary to design the bonding points based on the material and bonding requirements. Surface treatment is crucial for the bonding effect, and proper surface treatment can ensure the bonding effect. The surface treatment of the product before adhesive bonding should be cautious, and the correct processing tools and methods should be selected to ensure the best bonding effect.
Drying is a crucial step when using adhesives. Moderate drying is beneficial
