Composition of adhesive

1. Adhesives: Also known as adhesives and adhesives, two or more adhesive materials that have been surface-treated are firmly joined together and have certain mechanical strength. For example, epoxy resin, copper phosphate phosphate, white latex, and the like.

2. Solid material (base material): Determine the main physico-chemical mechanical properties of the joint. For example, epoxy resin, phenolic resin, etc.

3, curing agent:
a) Curing: The process of changing the liquid adhesive into a solid by physicochemical methods. Physical methods include dissolution and volatilization, emulsion condensation, and melt cooling; chemical methods polymerize adhesives into macromolecules.
b) Curing Agents: Chemicals used in the curing process.
4, curing accelerator: can promote the curing reaction rate, shorten the reaction time of the chemical substances, also known as the catalyst.
5. Toughening agent: It can improve the toughness of the cured adhesive, mainly esters and elastic compounds.
6. Filler: It can improve the mechanical strength of the joint.
7, other auxiliary materials: colorants, solvents (diluents), antioxidants and coupling agents.
