Adhesives Are Divided By Use Characteristics
Jul 07, 2021
①Water-soluble adhesive
Adhesives that use water as a solvent mainly include starch, dextrin, polyvinyl alcohol, and carboxymethyl cellulose.
②Hot melt adhesive
It is a solid adhesive for use after the adhesive is melted by heating. General thermoplastic resins can be used, such as polyurethane, polystyrene, polyacrylate, ethylene-vinyl acetate copolymer, etc.
③Solvent-based adhesive
A binder that is insoluble in water but soluble in certain solvents. Such as shellac, butyl rubber, etc.
④Emulsion type adhesive
It is mostly suspended in water, such as vinyl acetate resin, acrylic resin, and chlorinated rubber.
⑤Solvent-free liquid adhesive
It is a viscous liquid at room temperature, such as epoxy resin.
Adhesive is the medium between the label material and the bonding substrate, which acts as a link. According to its characteristics, it can be divided into two types: permanent and removable. It has a variety of formulas, suitable for different surface materials and different occasions. Adhesive is the most important component in the technology of self-adhesive materials and the key to label application technology.
