In today's rapidly evolving industrial environment, a material known as Micronized Wax powder is gradually becoming a favorite in various industries. This unique substance, produced through a special process into ultrafine powder, possesses numerous advantageous properties, including small and uniform particle size, low melting point, high hardness, and strong chemical resistance. These characteristics make it an indispensable component in industries such as coatings, inks, cosmetics, and plastic processing, significantly enhancing product performance and quality. In the coatings industry, the application of Micronized Wax is particularly widespread. It is used in the production of high-gloss solvent-based coatings, water-based coatings, powder coatings, can coatings, UV-cured coatings, and metal decorative coatings. This micro powder can significantly improve the wear resistance, scratch resistance, and surface smoothness of the coating, while also enhancing its leveling performance and water sensitivity. For instance, in automotive and industrial equipment coatings, the addition of Micronized Wax greatly extends the coating's lifespan and protective ability. The ink industry is another important area where Micronized Wax is applied. It is used in the formulation of letterpress water-based inks, solvent-based gravure inks, offset inks, and overprint varnishes. This micro powder can enhance the ink's dispersion and printing performance, thereby producing clearer and more durable printed images. In high-quality printed products such as magazine covers and packaging boxes, the use of Micronized Wax significantly improves the printing effect. Apart from coatings and inks, Micronized Wax is also gaining increasing attention in the cosmetics and personal care industry. It is a raw material for powder compacts, antiperspirants, and deodorants. The excellent properties of this micro powder enable it to provide better texture and performance in cosmetics. Additionally, Micronized Wax can be used as a film-forming wax, enhancing the surface sliding property and hardness of the coating without affecting its leveling performance and water sensitivity. In the field of plastic processing, Micronized Wax also plays a crucial role. It functions as a lubricant and dispersant, improving the processing performance and quality of plastic products. For example, in the production of plastic pipes and sheets, the addition of Micronized Wax significantly improves the surface quality and processing efficiency of the products. Moreover, Micronized Wax is also used in the formulation of hot melt adhesives, widely applied in processes such as hot stamping. With the continuous advancement of technology and the growing demand in the market, the application scope of Micronized Wax is expanding. Its versatility and effectiveness make it a valuable material in modern industrial production. As industries continue to pursue product quality and performance, Micronized Wax will pla...

On October 1st, 2025, the annual National Day will be held as scheduled, which is a joyful moment for the whole country to celebrate national prosperity and unity. Mid-Autumn Festival is approaching on October 6th, 2025. It is a traditional festival with a long history, and also a good time for family reunion. On this day, people admire the moon, eat mooncakes, express their longing and love to their loved ones, and enjoy the warmth and joy of reunion. This year, two festivals meet, and this moment is even more festive. All of us at Sunman sincerely wish you and your family happiness, safety, and success! Sunman's 2025 National Day and Mid-Autumn Festival holidays: October 1st (Wednesday) to October 8th (Wednesday), 2025 During the holiday period, Sunman will temporarily suspend normal office operations. But If you have any urgent inquiry, please feel free to contact us via email or phone at any time. We will reply to you as soon as possible.

The polyurethane resin used in the ink is generally made of a polyester/polyether polyol and an isocyanate, and has a molecular force of about 20,000 to 40,000. Its solvents are mainly benzene, ketone, ester solvents as the main solvent. In the research and development process, according to the environmental requirements of the ink factory and the printing factory, the corresponding benzene-free ink resin can be prepared by using a keto ester solvent or an alcohol ester solvent. Ink polyurethane resin features： 1. Excellent adhesion fastness to film substrates Polyurethane resin ink segment contains polar groups such as carbamate, allophanate ester, ester bond, ether bond, and polar groups formed on the surface of many polar substrates such as PET, PA, etc. Hydrogen bonds, in turn, form a linker with a certain degree of linking strength. After the polyurethane resin is made into an ink, it is printed on a polar plastic substrate surface with excellent adhesion fastness. 2. Good affinity and wettability with pigments Polyurethane resins for inks are generally prepared from polyester or polyether polyols, alicyclic diisocyanates and diamine/diol chain extenders and have a molecular weight of about tens of thousands. Due to the introduction of the urea bond in the PU resin, a polyurethane-urea resin (PUU) is formed so that it has good dispersion wetting properties to the pigment. 3. Good resin compatibility The polyurethane resin for ink has good compatibility with aldehyde and ketone resin, vinyl resin, etc. The user can add it according to the actual situation and his own craft formula to improve the ink's overall performance. 4. Excellent yellowing resistance In the preparation process, the polyurethane resin for printing ink mainly uses aliphatic polyester and aliphatic isocyanate as the main raw materials for synthesis. Compared with aromatic polyurethane, it has excellent optical stability, and the film has excellent yellowing resistance after film formation. 5. Excellent film formation Ink polyurethane resins are structurally different from polyurethane resins used in other fields. Traditional polyurethanes mainly react with polyester polyols/polyether polyols with isocyanic acid to produce hydroxyl terminated polyurethane resins. The polar groups in the molecular structure are carbamates. Mainly ester, molecular cohesion is insufficient to meet the filming performance requirements of ink resin. Therefore, the use of polyurethane resins for inks to introduce urea groups on the basis of conventional polyurethanes greatly improves the cohesive strength and film-forming properties of the resins themselves. 6. Wide compatibility of organic solvents and good solvent release Solubility of the organic solvent to the resin is achieved by the polarity of the solvent molecule attracting solute molecules, which is commonly known as the same type of miscibility; traditional polyurethane resin has extensive compatibility with organic solvents, ketones, es...
