What are the categories of adhesives?
According to material sourceNatural adhesiveIt is derived from substances in nature. Including protein, starch, dextrin, animal glue, shellac, glue, rosin and other biological adhesive; including asphalt and other mineral binders.Artificial adhesiveIt is made of artificial substances, including inorganic binders such as water glass, and organic binders such as synthetic resins, synthetic rubber, etc..
By usage characteristicWater soluble adhesiveWater used as a solvent adhesive, mainly starch, dextrin, polyvinyl alcohol, carboxymethyl cellulose and so on.Hot-melt adhesiveA binder that melts by heating and is a solid binder. General thermoplastic resin can be used, such as polyurethane, polystyrene, polyacrylate, ethylene vinyl acetate copolymer, etc..Solvent based adhesiveAn adhesive that is insoluble in water and dissolves in a solvent. Such as shellac, butyl rubber etc..Emulsion type adhesiveMost of them are suspended in water, such as vinyl acetate resin, acrylic resin, chlorinated rubber and so on.Solvent free liquid adhesiveAt room temperature, in a viscous liquid form, such as epoxy resin.Adhesives are the media between label material and adhesive base material and act as a link. According to its characteristics can be divided into two kinds of permanent and removable. It has a variety of recipes, suitable for different surfaces and different occasions. Adhesive is the most important component in the technology of self-adhesive materials, and it is the key to label application technology.
Synthetic adhesive can be divided into synthetic thermosetting resin adhesive, synthetic thermosetting resin adhesive and thermosetting elastomer adhesiveThese four types are synthetic adhesive and compound adhesive.
