What are the different types of adhesives?

1. Material sources:
Natural adhesive: It is derived from substances in nature. Including bio adhesives such as starch, protein, dextrin, animal glue, insect glue, skin glue, rosin, etc; This also includes mineral binders such as asphalt.
Synthetic adhesive: mainly refers to artificially synthesized substances, including inorganic adhesives such as water glass, as well as organic adhesives such as synthetic resins and synthetic rubber.
2. Usage characteristics:
Water soluble adhesives: adhesives that use water as a solvent, mainly including starch, dextrin, polyvinyl alcohol, carboxymethyl cellulose, etc.
Hot melt adhesive: It is a solid adhesive used by melting the adhesive through heating. Generally, thermoplastic resins can be used, such as polyurethane, polystyrene, polyacrylate, ethylene vinyl acetate copolymer, etc.
Solvent based adhesive: an adhesive that is insoluble in water but soluble in a certain solvent. Such as insect glue, butyl rubber, etc.
Lotion adhesive: It is mostly suspended in water, such as vinyl acetate resin, acrylic resin, chlorinated rubber, etc.
Solvent free liquid adhesive: It appears as a viscous liquid at room temperature, such as epoxy resin.
3. Divided by raw materials:
MS modified silane: The modified silane polymer end is methoxysilane, invented by Zhongyuan Group in 1978. The company is the only global supplier of modified silane raw materials. Based on this, Belgian Novan Technology has continuously researched and innovated, producing a series of sealants and adhesives for applications in construction, industry, automotive transportation, civil use, etc.
Polyurethane: Polyurethane, also known as polyurethane, is a general term for large molecular compounds with repeated amino ester groups on the main chain. It is formed by polymerizing organic diisocyanates or polyisocyanates with dihydroxy or polyhydroxy compounds.
Silicone: Silicone, commonly known as silicone oil or dimethyl silicone oil, is a polymer of organic silicon oxides. It is a series of polydimethylsiloxane with different molecular weights, and its viscosity increases with increasing molecular weight.
