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...

天然ゴム、ブチルゴム、スチレンブタジエンなどのエラストマーに最大65%の塩素を添加して作られる、無臭の淡黄色の樹脂です。塩素化ゴムは硬く、強靭で光沢のある塗膜を形成します。主に塗料、ワニス、接着剤、インク、紙コーティングに使用されます。また、床やプールの防水塗料にも使用されます。耐薬品性と耐湿性に優れています。 塗料中の塩素化ゴム： 塩化ゴム塗料は通常、塩化ゴム樹脂、改質樹脂、顔料/充填剤、添加剤、溶剤で構成されています。 施工時の温度制限なし： 塩素ゴムコーティングは、季節や温度に制限されることなく、-20 ～ 50°C の環境で塗布できます。 使いやすい： ほとんどの塩化ゴムコーティングは単一缶包装システムを採用しており、施工現場で他の成分を一時的に混合する必要はありません。包装ドラムを開封し、均一に混合すれば、コーティング剤をそのまま使用できます。 速乾性： 塩化ゴムコーティングは、溶剤の蒸発によって乾燥する物理乾燥型コーティングです。溶剤の放出速度が速く、塗布後すぐに乾燥して膜を形成します。室温で4～6時間放置した後、2回目の塗装が可能です。 厚いコーティングが得られます: 塩化ゴム系厚膜ペースト塗料は、高圧エアレススプレーで塗布すると、1回の塗布で約55～85μmの乾燥膜厚を実現できます。最高乾燥膜厚は120μmに達するため、少ない塗布回数で厚い塗膜が得られ、工期を短縮できます。 優れた接着性： 塩化ゴムコーティングは、鋼鉄や金属表面への密着性に優れています。同時に、塗膜形成剤に含まれる溶剤が層間に浸透して層同士を接着させ、コーティング層間の密着性を高めます。 優れた耐腐食性： 塩化ゴム自体は化学的に不活性な皮膜形成材料であるため、塗膜の水蒸気および酸素透過性は極めて低く、アルコールや酸の1/10に過ぎません。さらに、水、塩分、酸、アルカリ、酸化剤、各種腐食性ガスに対する優れた耐性も備えています。 メンテナンスに便利： メンテナンスの際、強固に付着した旧塗膜を剥がす必要はありません。溶剤の浸透により新旧塗膜が相互溶解し、強力な接着力を発揮します。塩素系ゴム塗料は他の塗膜の上にも塗布できるため、メンテナンスが非常に容易です。 優れた抗毒性と難燃性： 塩化ゴムコーティングの成分には「塩素」ポリマーが多く含まれているため、有毒細菌の増殖を抑制する性質があります。機器の表面が火源に接触した場合、コーティング膜が塩素ガスを分解し、一定の難燃効果を発揮します。 当社の商品は、Pergut Sシリーズをはじめとする世界的ブランドのほとんどと同等です。ご質問等ございましたら、お気軽にお問い合わせください。...
