PCL is a fully degradable polymer with good biocompatibility. When introduced into waterborne polyurethane, it can make waterborne polyurethane have shape memory.Shape memory waterborne polyurethane has attracted wide attention for its shape memory function, temperature sensitivity and moisture permeability. PCL3000 PCL4000 was used as the soft segment, and toluene diisocyanate was used as the hard segment to generate hydroxy terminated waterborne polyurethanes, which were crosslinked with water-disperable polyisocyanate to form a two-component waterborne shape memory polyurethane coating adhesive.The results show that the water-based polyurethane finish fabric with PCL4000 as the soft section has better waterproof performance, and the maximum hydrostatic pressure resistance of the coated fabric is 9.8kPa. Because of the crystallization property of PCL, the moisture permeability of coated textile is significantly improved between 35 ℃ and 50℃, which is increased by 4 ~ 8 times. The crystallization property of PCL4000 is stronger than that of PCL3000. The moisture permeability of the coated textile prepared in the former is stronger than that of the latter, and the moisture permeability is 5.95kg/(m2·d). In recent years, waterproof and moisture permeable coating has achieved rapid development in textile finishing industry. The technology has gradually changed from non-temperature-sensitive waterproof and moisture permeable textile coating to temperature-sensitive waterproof and moisture permeable textile coating.Experts also constantly perfect the method and technology of waterborne polyurethane modified, win min type of waterproof and moisture permeable fabric coating in the future to explore key should first focus on the improvement of waterborne polyurethane coated fabric touch Improve the water resistance and anticorrosive antibacterial properties of fabric coating, etc, this is very important to this kind of fabric coating applied to clothing market.With the improvement of people's awareness of environmental protection and the improvement of living standards, the market demand for waterproof and moisture permeable textile coating has a wider development prospect Sinograce Chemical company produces various types of polyurethane solutions for a variety of applications such as stripable coatings, water-based glues, etc  

Nano coating is a very advanced process in recent years. This high-tech coating is not only non-toxic and harmless, but also can effectively prevent moisture and moisture erosion. What benefits can nano coating bring to businesses. Improving Product Quality Nano coating can protect the product from PCBA layer.Assuming no such protection, once liquid such as water or sweat enters, the product may be directly damaged, but with the protection of nano waterproof coating, from the most conservative theoretical point of view at least after watering, the user has enough time to deal with emergencies, open the shell, blow dry, etc., which equals first aid time. Increase sales highlights If you let consumers choose the same price or different configurations of the same model, the products with water, moisture and corrosion resistance will be more attractive. For mobile phones, for example, you can start the regular version and the waterproof version of a certain model.Waterproof version is absolutely necessary for many people to choose, waterproof becomes a key factor in the transaction. Reduce after-sale cost Based on the actual feedback from the users of the nano-coating, the original after-sale rate was reduced from a percentage to ten thousand parts.Some foreign single products need to travel by sea to other countries' ports coating can also protect products from sea humidity, salt fog and other factors to a certain extent. Enhance brand competitiveness Nano coatings effectively improve product durability, prolong service life, and reduce repair rate all of which naturally help the company to build a good reputation and enhance the competitiveness of the brand.Branding is not just about spending $2 on a media AD, it's about advertising.It will provide high-quality products and services for many years, leaving a good impression in the hearts of consumers once formed a good product brand impression, it will bring unlimited benefits for the enterprise.

Nano coating is widely used in modern times, and all industries are in use. What are the benefits of nano coating for wooden furniture? Let us know about it today. 1 Texture is more transparent Wood furniture nano coating is combined with furniture paint to form a new nano coating that can act as a filter to re-reduce wood texture permeability more than 10 times higher than the permeability of traditional paint. Nanomaterials can resist oxidation 2 perfect finish The nano-coating of the wooden furniture perfectly fills the defects of leveling the paint surface. Meanwhile, the composite nano-coating has a very uniform gloss, no refraction, no horizontal traces, showing a bright, non-glare, warm and comfortable visual experience 3 Feel more smooth The nano-coating of sensewood furniture is made of a new antifouling nano-material, whose single molecule is one-fifth the size of a hair, and its fineness is much higher than that of traditional materials, so it presents an amazing effect 4 The coating is antifouling and easy to clean Nano coating of wooden furniture has magical anti-fouling performance, almost all kinds of common stains are difficult to adhere to the film layer even the most serious oily traces in life, coated furniture can also be wiped with a clean water rag Our company produces nano superhydrophobic, which is used for building and wooden surface, car body, car glass and so on.
