Adhesives refer to the technique of bonding together the surfaces of homogenous or heterogeneous objects. They have the characteristics of continuous stress distribution, light weight, or sealing, and low process temperatures. Bonding is particularly suitable for connection of different materials, different thicknesses, ultra-thin gauges and complex components. Bonding has enjoyed the fastest development in modern times and has a very wide application industry. It has a major impact on the advancement of science and technology and the improvement of people’s daily lives.
Adhesive classification:
1, according to the application methods can be divided into thermosetting, hot-melt type, room temperature curing, pressure-sensitive and so on.

3, the form of water can be divided into water-soluble, water-based, solvent-based and various solid-state and so on.
Synthetic chemists often like to classify adhesives according to their chemical composition.
Adhesive application:
1, silicone and silicone bonding: silicone adhesive, its characteristics: good flexibility, high temperature.
2. Adhesion between plastic and silicone (P+R): UV curing adhesive
TPU and plastic bonding (TPU+P): UV curable adhesive
Bonding metal and silicone (metal + R): UV curing adhesive
It is characterized by a fast curing speed, but is not suitable for double-sided bonding of black substrates.
3, plastic and silicone bonding (P + R): ordinary heat drying type, need to be cured at 90 degrees Celsius for 1 hour to cure, suitable for silk screen operation.
Plastic and Silicone (P+R), Silicone and Silicone (R+R), Plastic and Plastic (P+P), Plastic or Silicone and or Nylon, Plastic or Silicone and Stainless Steel, Plastic or Silicone and Aluminum, Suitable for Silk Screen Printing Or dot printing, which features long curing time, strong applicability, and high bonding degree.
