  • Strippable resin for preparing a temporary protective layer
    Strippable resin for preparing a temporary protective layer

    2024-03-23

    What is a peelable resin? Strippable resin is a special resin material with strippable properties (also known as removable film resin). It is often used in the preparation of protective films for electronic products, packaging of semiconductor devices, etc., which can protect these products more intact, and it is easy to peel off when it needs to be replaced or disassembled. When preparing the strippable resin, polymer, solvent, plasticizer and other substances are usually mixed and prepared by adjusting the proportion and process parameters. Features of strippable resin ①Strong strippable performance: under normal circumstances, the strippable resin has strong strippable performance, easy to peel off, and can leave no residue after stripping. ②High transparency: the strippable resin has good transparency, and the state of the covered item can be observed. ③Good machinability: the strippable resin can be processed by thermoforming, pressure molding, injection molding and other methods. ④Good pastability: the strippable resin can be easily pasted on various surfaces and is not affected by environmental changes such as temperature and humidity. Use of strippable resins 1.The polymer, solvent, plasticizer and other raw materials are mixed in a certain proportion. 2.The reaction accelerator is added to the mixed material for reaction. 3.Add stabilizer, antifreeze and so on for regulation. 4.Processing by thermoforming, pressure forming, injection molding and other methods. Next, a water-based strippable resin is introduced, which not only has high transparency, good film formation and toughness, but also has low odor, low voc and strong water resistance. It can be widely used in coating, spraying, screen printing and other scenes. Application suggestions: It can be used for temporary protection of tinplate, PU, PC, ABS, PET and other substrates; If you need peelable resin samples, please leave a message and the relevant staff will contact you as soon as possible or call the official hotline: +86 0551 63459511

  • Characteristics of waterborne polyurethane for inkjet printing and digital ink
    Characteristics of waterborne polyurethane for inkjet printing and digital ink

    2024-03-21

    With the development of the application of digital inkjet printing technology in the clothing industry, environmental monitoring is more stringent and the demand for small batch production and personalized customization is increasing. Therefore, the requirements for textile coating ink are becoming higher and higher, and the raw materials for the production of textile coating ink are becoming more and more important. There are a lot of digital hot ink on the market, most of them choose polyurethane resin this ink, good whiteness, good fluency and stability, which is the market reputation of this ink. As a link material for pigments and textiles, this resin produces paint inks with softness, toughness and elasticity. It has good compatibility with a variety of resins, and has water decomposition resistance and heat resistance. But the first impression this resin gives customers is expensive. At present, in the pigment ink material, good materials can ensure the whiteness of white ink, the brightness of color ink, the basic parameters of ink fastness. Ink whiteness, covering rate is the focus of everyone's attention, which has a direct relationship with a good color paste. Film transfer attaches importance to whiteness because the better the whiteness, the better the color of the ink printed on the white ink, if the color requirements are the same, the whiteness of the ink will be more ink saving. The coverage ratio directly affects the whiteness, the better the coverage, the higher the whiteness. Cover good ink, print white, do not leak the bottom, the product looks more beautiful. The fastness of the ink is also determined by the quality of the key material resin in the ink, the cost of a bottle of 1000 ml ink between the good resin and the cheap resin will be different by 10 yuan, but the good resin can improve the fastness of half a level, a very important half level. Without good materials, there will certainly be no good ink, but good materials need a good formula to become a good ink, there are dozens of materials in the ink, even a small change in each material, will affect the quality, need to re-test, in order to finally determine the formula. The following introduces a waterborne polyurethane Water-Based Emulsion For Fabric Ink BA-8311, which can be used in water-based pigment inkjet, white ink hot ink and other fields The resin features: ①Excellent physical properties; ②Excellent inking resistance; ③Good filterability and defoaming; ④Does not contain NMP, NEP and other cosolvents; If you need samples, you can apply for free by leaving a message in the pop-up window at the lower left corner. Relevant staff will contact you as soon as possible or call the official hotline: +86 0551 63459511
