Categorized by adhesive type
Water-based coating adhesive
(Abbreviated: water-based adhesive) Produced by emulsifying acrylic or polyurethane resins in water using specialized emulsification equipment. Its key advantages include variety, eco-friendliness, low cost, and long shelf life. Many coatings utilize water-soluble adhesives-such as those found on standard "sticker-booth" photo paper, self-adhesive PP, and domestic self-adhesive inkjet paper. Due to their functionality, eco-friendliness, low cost, and durability, water-based adhesives represent the future direction of coating technology. Disadvantages include poor film-forming properties and poor wash fastness.
Solvent-based coating adhesive
(Abbreviated: solvent-based adhesive) Produced by dissolving acrylic or polyurethane resins in organic solvents (such as toluene, DMF, or MEK). Advantages include excellent film formation, high durability, and long shelf life; it is currently the most widely used type of coating adhesive. Disadvantages stem from the use of organic solvents, which raises environmental concerns. In particular, rising oil prices have caused solvent costs to skyrocket; consequently, high costs have led to the use of lower-quality solvents, often resulting in failure to meet environmental standards. Furthermore, as nations tighten environmental regulations, requirements for coating adhesives are becoming increasingly strict. Common market examples include imported solvent-based high-gloss photo paper, imported solvent-based inkjet paper, self-adhesive RC waterproof photo paper, and self-adhesive transparent PET film.
Hot-melt pressure-sensitive adhesive
(Abbreviated: hot-melt adhesive) A type of self-adhesive product manufactured by heating a mixture of synthetic rubber, resin, and rubber oil until molten, then coating it onto a substrate (such as printing media). Its primary advantage is low cost; however, its drawbacks include significant temperature sensitivity regarding adhesion and a shorter shelf life. It possesses strong adhesive properties, excellent thermal stability, and superior water and weather resistance; it is free of impurities and easy to work with. Hot-melt pressure-sensitive adhesive is a thermoplastic adhesive; within a certain temperature range, its physical state changes with temperature while its chemical properties remain constant. It is non-toxic, odorless, and an environmentally friendly chemical product. Common applications include thin, high-gloss self-adhesive photo paper (such as for labels), self-adhesive inkjet paper, and RC self-adhesive waterproof photo paper.
