Ink is a huge part of our everyday lives. Without it we wouldn't be able to print money, make road signs, or mail packages. The different types of ink include: ·Pen ink ·Printer ink ·Erasable ink ·Phosphorescent ink ·Fluorescent ink ·Adhesive ink ·Invisible ink ·Edible ink Pen Ink Pen inks are oil or water-based and contain additives that dye the ink a certain color. For instance, black ink pens contain carbon black, while blue ink pens contain phthalocyanine blue. Printer Ink Most color printers follow the CMYK (cyan, magenta, yellow, black) model. To make new colors and create an image, the printers will layer tiny dots of the four printer colors. Erasable Ink The erasable pen was invented in 1979, but took 10 years to perfect. The ink inside is made of a liquid rubber cement, which makes it possible to remove the pen marks via a combination of friction and heat. Phosphorescent Ink Phosphorescent ink is made using strontium aluminate and phosphors. These chemicals absorb and store light energy until the light disappears. Once it's dark, the energy is converted into visible light known as the glow. Fluorescent Ink Fluorescein is a chemical used to make highlighter ink. It's what gives the highlighters their neon color when the ink is applied to the paper. Different additives are used depending on which color highlighter you're using. For instance, a chemical known as pyranine is used to make yellow highlighters. Adhesive Ink Temporary tattoos and decals are made from regular ink with a special coating that's printed onto transfer film. When moisture is applied, it soaks through the film and transfers the image onto the surface. Invisible Ink Write a secret message and then uncover it using heat or light. Many items in your kitchen can be used to create invisible ink including: lemon juice, milk, clear soda, and vinegar. This ink is also often used by concert venues or theme parks as stamps for admission. Edible Ink Edible inks are made from water, sugar, and FDA-approved colorants. They're safe to eat and often are used to print photos or logos on cakes, cookies, and candy.

Vinyl resin has relatively stable chemical properties, and has excellent insulation and corrosion resistance. We would like to share some applications to you as follows: 1. GRP pipes and storage tanks All kinds of glass fiber reinforced plastic products such as cans, pipes and containers with anti-corrosion requirements. 2. Flue gas desulfurization All coal-fired thermal power plants have FRP chimneys for flue gas desulfurization, which are typical applications of vinyl resin. 3. Iron and Steel Industry Vinyl resin is used for maintenance coatings. It is used in the pickling section area, waste acid tank and area of stainless steel cold rolling and hot rolling production line, FRP grid, cover plate, dilute acid tank, waste water tank, etc. Office. 4. Chemical industry Used in lining of titanium dioxide plant, fertilizer plant, phosphate plant and other equipment, acid-resistant bricks and ground granite joints. 5. Petrochemical industry, papermaking, printing and dyeing industry Vinyl resin is used for storage tank lining FRP, wastewater tank lining, pipeline coating anticorrosion, wall surface, steel structure anticorrosion, etc. 6. Overall Mortar Floor One is the overall anti-corrosion floor that is resistant to acid, alkali and salt; the other is the anti-static, dust-proof, food-grade clean floor. 7. Chemical fiber and textile industry Vinyl resin is used in equipment linings, wastewater ponds, pipeline coatings, etc. 8. Solvent resistance and flame retardant Vinyl resin is suitable for the requirements of solvent resistance in most occasions, and is suitable for flame retardant requirements of buildings below B1. 9. Wind power blades Vinyl resin can replace epoxy resin because of its good toughness and fatigue resistance. 10. Electrolytic cell (pool), electroplating In the non-ferrous metal smelters, the most commonly used electrolytic copper, electrolytic nickel pools and tanks are often made of vinyl resin to make resin concrete integrated electrolytic tanks, or as the first choice for glass fiber reinforced plastic lined resin, and are used in workshop floor, FRP grille, cover Board and other places. Vinyl resin is often used in the plating tank lining and floor of the plating workshop.

Dear All Partners and Customers, Lunar New Year is on the way and it has been an amazing year working with you.

Best regards, Sino Sunman

Plastisol ink is a PVC (polyvinyl chloride) based system that essentially contains no solvent at all. Along with UV ink used in graphic screen printing, it is referred to as a 100% solid ink system. Plastisol is a thermoplastic ink in that it is necessary to heat the printed ink film to a temperature high enough to cause the molecules of PVC resin and plasticizer to cross-link and thereby solidify, or cure. The temperature at which most plastisol for textile printing cures at is in the range of 149 °C to 166 °C (300 °F to 330°F). Plastisol ink can be printed on many items that can withstand the heat required to cure the ink and is porous enough to permit good ink adhesion. They do not dye the threads of a fabric like traditional dye material. Plastisol screen printing ink wraps around the fibers and makes a mechanical bond with the fabric. Screen printing plastisols will not adhere to non-porous substrates such as plastic, metal, wood and glass. They also will not adhere to water-proof nylon material without adding a bonding agent/catalyst. Plastisol ink is made up PVC particles suspended in a liquid plasticizer, it is very durable, flexible, and is commonly used in apparel printing. Plastisol is thick and opaque and it can be mixed easily to create just about any color imaginable. With plastisol ink, we can create special effects like suede, glow-in-the-dark, glitter, shimmer, or metallic. Plastisol is most commonly used on dark-colored fabrics, and it is ideal when printing designs that are less detailed and very colorful. The four major components that go into the formulation of Plastisol inks are (1)Polyvinyl Chloride (PVC)  (2)Plasticizers  (3)Fillers  (4) pigments. Additives A word of caution about ink additives, it’s easy to upset the chemical balance of plastisol inks by using the wrong additives, or by adding too much of an additive – even if it is the correct type of additive. The result can be t-shirt ink that never cures properly, a problem that may not be discovered until your customer washes a shirt and the design falls (i.e. color lose, adhesion or cracking). To avoid this problem, use only those additives recommended by the manufacturer, and read the Technical Data Sheets for each ink and additive, and carefully follow their instructions. Never add mineral spirits to plastisol ink. Although mineral spirits will make it easier to print at first, soon the ink will become even stiffer and harder to print than before. Also, it is possible that mineral spirits will prevent the ink from curing properly. Ink Storage Store plastisol inks at room temperature. Prolonged exposure to temperatures above 90º F (32º C) can cause the ink to start to cure while it's still in the container.
