Matt Coating Paste

Screen printing Matt Coating Paste is a kind of coating material used in screen printing to make the surface of printed matter present a matte effect. The following is its specific introduction:

Main component:
It is generally composed of special resins, additives and fillers, etc., without solvents and heavy metals, meeting environmental protection requirements. A few may contain specific solvents.

Characteristics:
The matte effect is remarkable: It can effectively reduce the surface gloss of printed materials, creating a soft and understated visual effect. It is often used in products with special requirements for gloss, such as high-end cosmetic packaging and electronic product shells.
Strong adhesion: It can form a firm bond on the surface of various substrates, such as PVC, PET, metal, glass, etc. Even after friction, wiping and other treatments, it is not easy to fall off or crack.
Good weather resistance: It has excellent lightfastness, heat resistance and chemical corrosion resistance, and can maintain a matte effect and coating integrity for a long time. It is suitable for outdoor advertising, automotive decoration and other fields.
High adjustability: Usually, its viscosity, drying speed and leveling property can be adjusted by adding thinners, leveling agents and other additives to meet the requirements of different printing processes and substrates.

Use technology:
Dilution and stirring: According to the printing requirements and the characteristics of the substrate, add an appropriate amount of thinner to the Matt Coating Paste, stir evenly, and make the coating achieve the appropriate viscosity and fluidity. If it is necessary to improve the leveling property of the coating, a leveling agent can also be added.
Printing operation: Pour the well-mixed coating into the hopper of the screen printing machine. Select the appropriate mesh size of the screen and the hardness of the scraper according to the material and thickness of the substrate for printing, and then proceed with the printing. During the printing process, maintain a certain printing speed and pressure to ensure that the coating is evenly transferred to the surface of the substrate.
Drying treatment: After printing is completed, based on the material of the substrate and the characteristics of the coating, select an appropriate drying method, such as natural drying, hot air circulation drying or UV ultraviolet drying, etc., to ensure that the coating is fully dried and cured, forming a hard and wear-resistant matte coating.

Application field:
It is widely applied in multiple industries such as printing, packaging, decoration, electronics, and automobiles. For instance, in the printing industry, it is used to create matte effects for high-end book covers, posters, brochures, etc. It is used in the packaging industry for surface treatment of packaging for cosmetics, food, medicine, etc. It is used in the decoration industry for surface decoration of materials such as glass, metal and wood. It is used in the electronics industry for surface coating of electronic products such as mobile phone casings and computer casings; It is used in the automotive industry for matte treatment of automotive interiors, instrument panels and other components.

Advantage:
Personalized customization: According to the customer's demands and design requirements, the formula and process of the coating can be adjusted to achieve personalized customization of different matte finishes, colors and texture effects, meeting the diverse needs of the market.
Simple operation: Compared with traditional printing processes, the operation of screen printing Matt Coating Paste is relatively simple, with lower requirements for equipment and personnel. It is easy to get started and master, and is suitable for small and medium-sized production and manufacturing.
High cost-effectiveness: It can reduce production costs to a certain extent, improve production efficiency, and at the same time increase the added value and market competitiveness of products, bringing better economic benefits to enterprises.

Precautions:
Substrate treatment: Before printing, the surface of the substrate needs to be cleaned and treated to remove oil stains, dust, moisture and other impurities, so as to improve the adhesion of the coating and the printing quality.
Environmental control: During the printing process, it is necessary to maintain relatively stable temperature, humidity and ventilation conditions in the workshop to avoid adverse effects of excessively high or low temperatures and humidity on the performance of the coating and printing quality.
Storage and preservation: Matt Coating Paste should be stored in a cool, dry and well-ventilated environment, avoiding direct sunlight and high-temperature environments. At the same time, it is necessary to pay attention to sealed storage to prevent the coating from drying, caking or deteriorating.
