Water Based Polyurethane Peelable Protective Coating PU-207 is a protective resin made of waterborne polyurethane base material with advanced technology. The water-based peeling paint made from this is bright in color, fine and uniform in particle size, coating on the surface of automobiles, furniture, electrical appliances and other objects as a protective coating, has good protection, can form a layer of continuous, uniform, strong protective coating on the surface of complex shapes, can isolate the erosion medium, protect the substrate surface is not easy to wear, abrasion, scratch, moisture-proof, rust, corrosion prevention, Increase the added value of the coated goods.After the completion of the protection period, it can be convenient to peel off the film layer and restore the original appearance of the object.

Acrylic acid Important organic synthesis raw materials and synthetic resin monomer Acrylic resin is an important organic synthesis raw material and synthetic resin monomer, is a very fast polymerization rate of ethylene monomer.Is the simplest unsaturated carboxylic acid, consisting of a vinyl group and a carboxylic group. Most of them are used to manufacture methyl acrylate, ethyl ester, butyl ester, hydroxyethyl ester and other acrylates.Acrylic acid and acrylate can be homopolymerized and copolymerized, the polymer used in synthetic resin, synthetic fiber, superabsorbent resin, building materials, coatings and other industrial sectors.

Choice of water-based adhesive Application index Some packaging and printing enterprises reflect that some water-based adhesives will degummy soon after gluing; Viscosity is not stable, sometimes bond firmly, but sometimes not bond; It works well in hot weather, but it doesn't work in cold weather.In fact, this is due to the lack of understanding of water-based adhesive application indicators. The preparation method and production process of different types of water-based adhesives are different, so their chemical and physical properties are also different, that is, the application index is different.The most important application indexes of water-based adhesives in packaging and printing industry mainly include bond strength, high and low temperature resistance, moisture resistance and stickiness. The defects such as weak bond, degumming and brittle film often occur in practical application are basically caused by the above four application indicators. High cost performance Choose water-based adhesive, should be "quality first, price second" as the principle. However, some packaging and printing enterprises view is very one-sided, mistakenly think that the higher the price of water-based adhesive, the better the quality; Otherwise, the quality is worse. In fact, this is not absolute. When choosing water-based adhesives, we should first understand the characteristics of the processed products and choose the adhesives with higher cost performance, which is a reasonable way to choose and buy. Different products in different fields of application indicators are different processes, here is only a brief introduction, if you need to know more products in detail, you can contact our technical staff for consultation.

Water-based adhesive with high polymer, water-soluble resin as the main raw materials, water as the solvent, odor is small, environmental protection and non-toxic. With the continuous improvement of people's environmental awareness, water-based adhesives have become the mainstream of the market in recent years. In practical application, some packaging and printing manufacturers do not know enough about water-based adhesives, which causes some quality problems. Among them, the water-based adhesive "difficult to bond" problem is one of the technical bottlenecks plaguing many packaging printing enterprises.In order to let more packaging and printing enterprises understand water-based adhesive, the following will be elaborated from the characteristics and selection of water-based adhesive two aspects, I hope to help you. Characteristics of water-based adhesive Any kind of adhesive for substrate is not omnipotent, an adhesive is only suitable for bonding some or some kind of specific material. Such as Lamination Adhesive SA-2800X and Water Based Dry Laminating Adhesive SA-228 series water-based adhesives are mainly used for bonding between paper/paper, PET film/paper, BOPP film/paper, wood/paper and other substrates. Every kind of water-based adhesive has its "inherent characteristics". The inherent characteristics of water-based adhesive mainly include appearance (product appearance and film appearance), solid content, density, pH value, solvent ratio, opening time, high and low temperature resistance, initial viscosity, curing viscosity, etc. The bonding mode of water-based adhesive is generally divided into three kinds: machine adhesive, hand adhesive, machine adhesive and hand adhesive. Different bonding modes correspond to different inherent characteristics. For example, when using machine adhesive, water-based adhesive opening time is required to be short; When using hand adhesive, the water-based adhesive is required to open for a long time; When the film surface bonding, the adhesive film is flexible and the curing viscosity is high.
