(1) Epoxy adhesive Epoxy adhesive is composed of epoxy resin, curing agent, toughening agent, filler, diluent, accelerator, coupling agent, etc. It has high strength, small shrinkage, good sealing and insulation, and resistance to oil, water, and general chemicals. Temperature resistance, wear resistance, and conductive properties can also be obtained by appropriately changing the ingredients. Can bond various metals and most non-metallic materials. Therefore it is widely used. (2) Phenolic-nitrile adhesive Phenolic-nitrile adhesive consists of phenolic resin, nitrile rubber, additives, solvents, and coupling agents. It has high strength, especially high peel strength, wide operating temperature range, oil resistance, and resistance to oil and water. Temperature resistance, wear resistance, and conductive properties can also be obtained by appropriately changing the ingredients. Can bond various metals and most non-metallic materials. Therefore it is widely used. (2) Phenolic-nitrile adhesive Phenolic-nitrile adhesive consists of phenolic resin, nitrile rubber, additives, solvents, and coupling agents. It has high strength, especially high peel strength, wide operating temperature range, oil resistance, vibration resistance and good durability. Can bond metal, glass, leather, paper, wood, PVC, nylon and other materials. (3) Anaerobic adhesive Anaerobic adhesive does not solidify when in contact with oxygen or air, hence its name. Its main features are: Single liquid type, low viscosity, easy to wet and penetrate, fast curing speed at room temperature, high strength, good sealing, high pressure resistance (30MPa), long service life, etc. Mainly used for joint surface sealing, thread locking and blocking of pores and blisters in castings. (4) Chloroprene adhesive Chloroprene rubber is composed of chloroprene rubber, metal oxides, resins, fillers, antioxidants, accelerators, etc. It has good elasticity and is resistant to shock and vibration. Mainly used for bonding rubber, leather, wood to themselves and to metal. Vibration and good durability. Can bond metal, glass, leather, paper, wood, PVC, nylon and other materials.

Adhesives based on organic compounds. Take Epoxy Adhesive as an example. 1. Main ingredients (1) Epoxy resin: sticky. (2)Curing agent: Reacts with A and cures. (3)Plasticizer: Improve resilience. (4)Thinner: Adjust the consistency of A. Commonly used are toluene, acrylic and the like. (5)Packing: Improve some physical or mechanical properties of the binder and reduce the amount of binder. 2. Bonding process (1) Surface treatment: Machining, cleaning, etc. ; (2)Joint preparation: The joint method has a great influence on the bonding strength: Overlap, slot, socket, etc. (3) Glue adjustment ; (4) Glue: 0.2~0.4mm, then fit and press it, and fix it with a clamp. (5)Cure: 24 hours at room temperature, heating to cure can shorten the curing time.
