It is applicable to industries such as automobiles, ships, grid structures, mechanical manufacturing, containers, railways, Bridges, boilers, and steel structures 2. It is applicable to metal anti-rust coating in industries such as industrial equipment, mechanical manufacturing, hardware and electrical appliances, and household appliances Matching solution:Waterborne polyurethane primer + waterborne polyurethane intermediate coat + waterborne polyurethane topcoat

The following types of resins are commonly used in water-based glass resin, each with its own characteristics. They can be selected according to specific needs: Acrylic resin • Advantages: It has excellent weather resistance, light and color retention, relatively high hardness, and a relatively fast drying speed. It can form a hard and glossy coating film on the surface of glass paint, with good adhesion to glass. Moreover, water-based acrylic resin uses water as the solvent and has superior environmental protection performance, meeting current environmental protection requirements. For instance, it is widely used in some glass handicrafts and decorative glass products, which can maintain bright colors and a shiny appearance for a long time. • Disadvantages: Its solvent resistance and wear resistance are slightly inferior to those of some resins. In some application scenarios that require frequent contact with organic solvents or excessive friction, the coating film may be damaged. Polyurethane resin • Advantages: It has excellent comprehensive performance, good flexibility of the coating film, excellent wear resistance, and the hardness can be adjusted to an appropriate level through formula adjustment. At the same time, it performs outstandingly in terms of chemical corrosion resistance, water resistance, etc. It has a good adhesion to glass and can adapt to various different usage environments. It can be applied to the coating of frequently wiped and cleaned glass furniture, glass doors and Windows, etc., and can maintain the integrity of the coating film and stable performance for a long time. • Disadvantages: The cost is relatively high, the preparation process may be more complex, and the storage stability of some polyurethane resin products needs to be strictly controlled, with certain requirements for storage conditions such as temperature and humidity. Epoxy resin • Advantages: It has extremely strong adhesion to various substrates such as glass, good chemical stability, and excellent corrosion resistance. The water-based glass paint made from it can be used for protective coating of some glass products with high chemical protection requirements, such as laboratory glassware and glass pipes involved in chemical production, effectively blocking the contact of external corrosive media with the glass surface. • Disadvantages: Its weather resistance is relatively weak. When exposed to outdoor environments for a long time, it is prone to discoloration and powdering. Moreover, the texture of epoxy resin after curing is relatively brittle, and its flexibility needs to be improved by adding appropriate additives and other means. Sinograce Chemical produces waterborne polyurethane resin for waterborne glass baking varnish ink.

What is peelable resin? Water-based peelable resin is an environmentally friendly polymer material that dissolves in water to form an emulsion, and after drying, it can form a film that can be easily peeled off. Imagine that it is like the "tearable nail polish" we played when we were young. Applying it can protect the nails and tear off the whole piece when not needed. The principle of water-based peelable resin is similar, but the application range is much wider. This resin is mainly made of environmentally friendly polymer materials such as acrylic acid and polyurethane. It does not contain harmful solvents and uses water as a dispersion medium. Therefore, it is very friendly to the human body and the environment. Its "peelable" properties come from special molecular designs that can be firmly attached when needed and completely peeled off when not needed. The role of water-based peelable paint Three main unique functions of peelable coatings 1.Temporary protection: During the production and transportation of electronic products, automobiles, furniture and other products, peelable paint can form a layer of "invisible protective cover" to prevent the surface from being scratched or contaminated. 2.Convenient removal characteristics: When protection is no longer needed, the whole piece can be peeled off like tearing a sticker, leaving no residual glue, and does not damage the substrate or paint film. 3.Environmentally friendly cleaning functions: Some special formula peelable paints can even be used to clean the surface, taking away dust and stains when peeling off. Water-based peelable applications Application fields of peelable coatings Industry applications Electronics Industry: Protecting the case and screen of precision electronic products such as mobile phones and tablet Automobile manufacturing: protect the paint surface of the car body during transportation and easily peel off after arrival at the store Home decoration: protect doors, windows, floors, etc. during construction to avoid paint and cement pollution Industrial equipment: Temporarily protect the precision machining surface to prevent rust and scratches Art field: as a protective layer for temporary display, or create special artistic effects Advantages of peelable coatings Advantages of peelable coatings compared to previous peeling technology Surface protection has always been an important topic in the fields of industrial protection, electronic product packaging, automobile transportation, etc. Although traditional protection methods such as PE protective film, tape, wax protection, etc. have certain effects, they all have various limitations. The emergence of peelable coatings (water-based peelable paints) has brought more efficient, environmentally friendly and convenient solutions. So, what are its advantages compared to traditional stripping technology? Let's compare and analyze from multiple Comparison items Traditional techniques (PE film/tape/wax) Peelable coating Env...
