Requisite Properties •Printing : cylinder contamination, metastatic, electrostatic field, blocking ability •Post process : Laminate, Boil, Retort, etc. •Substance resistance : soup base, repellant, etc. •Film properties : scratch resistant, heat resistant, oil resistant Process While the press is in operation, the metal printing cylinder is partially immersed in the ink tray, filling the recessed cells, which are intaglios on the cylinder. As the cylinder rotates, it draws excess ink onto its surface and into the cells. The doctor blade removes the excess ink, leaving in the cells the right amount of ink required before it makes contact with the paper. Next, the paperboard gets sandwiched between the impression roller and the gravure printing cylinder, where the ink gets transferred from the recessed cells to the web. The purpose of the impression roller is to apply force to ensure even and maximum coverage of the ink. The inked paperboard then goes through a dryer because it must be scorched before going through the next color unit and accepting another coat of ink. Principle of gravure printing

Almost anything that you want to make it glow. You can mix it into a transparent or semi-transparent medium such as resin, wax, paint, ink, paste, plastics, rubber, fabric, caulking, ceramic glaze, nail-polish etc. There are industrial applications for safety, for novelty, for fun, for household using in arts and crafts. Glow in the dark pigment can meet expectation of all purposes above-mentioned. Some detailed applications, such as egress signs, sudden darkness orientate system, outline marking, cell phone case, keyboard cover pad, screen-printing ink, night-glow shirts, toys, clothes, glass mosaic, garden decoration lights, etc., have been applied. See some application samples in picture below: a. b.

Polyvinyl Butyral (PVB) is a water-insoluble thermoplastic polymer known for its excellent binding and film-forming properties. It dissolves readily in a wide range of organic solvents and shows good compatibility with many other polymers. With superior elasticity and optical transparency, PVB suits diverse industrial uses. Both high- and low-viscosity grades are available, with glass transition temperatures tailored to specific applications. Stability can be further enhanced via cross-linking. As a result, PVB serves as a key binder in paints, primers, adhesives, metal powders, and ceramics, as well as an interlayer in laminated safety glass, making it indispensable across multiple industries. Field of Application: Wash Primer PVB-based "wash primer" is widely used on metal surfaces such as storage tanks, ships, aircraft, bridges, dam locks, and electronic appliances. Compared to conventional materials, it offers superior corrosion protection, better adhesion, faster drying, and easier application. Strong anchoring is achieved through a complex interaction of synthetic resin, pigments, phosphoric acid, and metal ions. Foil Coatings Applying PVB solution onto metal foils (e.g., aluminum, brass, tin, lead, iron) improves mechanical strength, moisture resistance, and printability. Adhesion can be further enhanced by stoving at up to ~140°C.   Wood Paints PVB is widely used in wood sealers and topcoats, imparting toughness, flexibility, and impact resistance. Common blends include PVB with phenolic resins, shellac, or nitrocellulose. As a knot sealer, it prevents terpene and resin bleeding.   Leather Paints Combined with nitrocellulose and plasticizers, PVB provides excellent adhesion, high elongation, and crack prevention while maintaining leather flexibility.   Stoving Paints Blends of PVB with phenolic, melamine, or urea resins are ideal for stoving paints. Adding 5–25% PVB to phenolic resin transforms a brittle film into one with good flexibility, excellent leveling, a pinhole-free surface, and improved alkali resistance.   Powder Coatings PVB blended with epoxy resins improves edge covering and prevents pulverization.   Adhesives PVB-phenolic mixtures bond metal, glass, leather, wood, fabric, paper, and more. After solvent removal, surfaces are heated and pressed together. Typical curing: 160°C for 15–30 minutes.   Printed Circuit Board Adhesives A PVB-phenolic blend meets key PCB adhesive requirements: high peel strength, blister resistance, and good dielectric properties, ideal for bonding phenolic prepregs to copper foil.   Printing Inks PVB is used in gravure, letterpress, and flexographic inks, offering flexibility, strong adhesion, and toughness.   Hot-Melt Adhesives Fusing PVB with plasticizers and fluxing resins produces hot-melt adhesives that form tough, clear films with good adhesive strength.   Ceramic Binders In ceramic electronic components, PVB acts as a binder, providing green strengt...
