Fabric coating finishing is to evenly coat a layer of molecular film on the surface of the fabric to give the fabric with various functions and expand the use of the fabric. Compared with other coating materials, polyurethane coating has high tensile strength, large elongation, good elasticity, good wear resistance, heat resistance, low temperature resistance and aging resistance, and is a high-quality coating material. The main processing methods of polyurethane coated fabrics are dry and wet. Dry coating can be divided into direct coating and transfer coating, especially transfer coating. Direct coating is the coating agent directly coated on the surface of the fabric, mainly used to make thin waterproof clothing. Transfer coating is the preparation of the solution type polyurethane slurry on the release paper, after drying to form a film, and then the use of adhesive, extrusion, drying to make the base cloth and film closely together, and finally the release paper peel, can form a coated fabric with a pattern. There are three main wet coating methods: direct coating method, that is, the prepared polyurethane slurry is first coated on the substrate, and then wet solidified to form a porous cortical film; The second is the film method, that is, the polyurethane slurry is coated on the polyurethane film, the wet film is formed into a porous layer, and then it is fitted on the background cloth; The third is the impregnation method, that is, the base cloth is impregnated in the polyurethane slurry, and then the excess slurry is scraped away, and then the porous skin film is formed by wet solidification. Sinogracec Chemical is a service-oriented company with functional textile technical services as the core, which can provide customers with waterproof, antibacterial, flame retardant and other functional solutions such as clothing, leather, luggage, wall cloth wallpaper, yarn, ribbon, shoe materials.

Leather finishing is generally divided into three parts:Primer coat, middle coat, and topcoat.Primer requires strong adhesion, hiding power, good embossing formability and stereotyping, and the middle coating further covers and modifies the color, and finally achieves the visual and physical performance requirements through the topcoat.With a specific topcoat, the effect of extinction or light can be created. Waterborne polyurethane resin is the main material commonly used in leather coating. Its film forming performance is good, the bond is firm, and the coating has the characteristics of high wear resistance, high elasticity, water resistance, weather resistance, cold resistance, chemical resistance and so on.After finishing, the finished leather feels full and comfortable, which improves the grade of the finished leather and plays a role in protecting the leather. In order to meet customers' pursuit of quality and meet the most stringent environmental requirements,SinograceChemical launched two single-component waterborne polyurethanes, which are polymerized from aliphatic isocyanates.Excellent adhesion, good adhesion resistance, comfortable feel, no yellowing, good weather resistance. The products are widely used in leather shoes, belts, sofas and luggage leather and other leather products. For leather top finish to provide excellent gloss and permeability, excellent wear resistance and weather resistance.

water base varnish for glass Does not contain benzene, esters and other harmful solvents, does not contain free TDI, does not burn, is the latest environmental protection glass process paint, by the international and other authoritative verification institutions assessed as the real green environmental protection products. Solve problems It is required to blister at 75℃ for 30 minutes and it is required to be dense. Soak in ethanol for 48 hours without fading. Water-based glass paint is a water-based varnish used on glass substrates. At present, there are single-component self-drying type, single-component baking type, two-component self-drying type. Single-component self-drying type is prepared by water-based polyurethane emulsion and adhesion enhancer; The one-component baked type is prepared by emulsion containing -OH or carboxyl group and water-dilutive amino resin; The principle corresponds to oil-based baking paint. The two-component self-drying type is composed of water-based epoxy resin plus binary amines, etc., and the principle corresponds to the two-component self-drying paint, such as epoxy floor paint, two-component PU paint, etc. Pure water-based glass paint belongs to glass base varnish. What is the difference between water-based glass varnish and oil-based glass varnish? 1.Water-based glass varnish water as a diluent, and oily glass paint generally use banana oil (banana water) to do diluent, everyone knows that banana oil (banana water) is toxic, from this point of view water-based glass paint is more environmentally friendly and safe than oily glass paint, and when cleaning the spray gun and mold with water-based glass paint, you can clean it with water. And the use of oil-based glass paint, usually use the water (banana water) to clean the spray gun and the like. 2. The aging resistance of water-based glass varnish is stronger than that of oil-based glass varnish. 3.In terms of adhesion, water-based glass varnish is better than oil-based glass paint. 4. Water is more expensive than oil. Sinograce Chemical production for glass ink resin, applied to various types of glass, high hardness, good wear resistance, uv resistance, good water resistance, good adhesion.

Water-based coatings, acrylic resins are commonly used resins that can not be avoided, commonly used metal coatings, ABS, PC coatings, glass coatings that require hardness, most of them will be applied to acrylic resins, especially solid acrylic resins. There are many varieties of solid acrylic resins, and some solid acrylic resins can be used to produce water-based paints, including the popular light-curable UV radiation coatings and high-solid coatings. With the enhancement of people's environmental awareness, water-based coatings must be the mainstream. Advantages of solid acrylic resin The cost of storage and transportation is low and the safety is good Most solid acrylic resins take methacrylate as the main monomer, and its weather resistance and chemical resistance are better than that of acrylic monomer and styrene. It has good promotion value in external architectural coatings, container and automobile repair paint. Acrylic resin Since some types of solid acrylic resins can be used as water-based UV-curable paints and high-solid paint, adjusting monomers can produce low pollution and light odor acrylic architectural coatings for external use, solid acrylic resins help the coating industry to develop low pollution coatings. Domestic solid acrylic resin has been mass-produced, in some properties, such as dissolution rate, weather resistance and imported resin has the same effect, for the promotion of acrylic paint is making new contributions. Slicone modified acrylic resin In addition, silicone modified acrylate resins are also at the forefront of development, because they can be used in the automotive industry for elastic topcoats and general purpose primers. Organosilicon modified acrylate coating is a kind of coating with excellent properties, which introduces organosilicon polymer into acrylate structure by reaction. The silicone chlorane-acrylic resin coating has good properties and excellent adhesion to non-ferrous metals and various plastics. Sinograce Chemical 20 years of service water based coating customers, corresponding to different substrate needs, there are corresponding water based acrylic resin products, consulting three liters customer service+8615755193346 can consult more product information, obtain technical guidance.
