Fabric coating is a kind of fabric treated by a special process. It can form a uniform layer of covering material on the surface of the fabric, so as to achieve waterproof, windproof, breathable and other functions. Textile Coating, also known as glue coating, that is, acrylic coating, is the most common and most common kind of coating at present. As a textile person, you must know 15 kinds of coa...
First, the principle of adding water-based ink additives When using water-based ink additives, there are some basic principles that need to be followed. First, the resin and ink should be combined first, and then additives are added. Secondly, the appropriate time and method of addition should be selected according to the type and use of the selected additives. Second, the right steps 1.With resin...
Water-based acrylic resin and water-based acrylic emulsion have the following differences: 1.Appearance: • Water based acrylic resin: available in a variety of forms, both solid and liquid. Solid water-based acrylic resin is powder, need to be diluted with water after use; Liquid water-based acrylic resin can be transparent or milky liquid, its particle size is relatively small, generally in a nan...
Aqueous acrylic emulsion High viscosity is a monomer polymerization emulsion with good self-crosslinking performance, which helps to improve the density and water resistance of the film. The high hardness ensures the stability of the coating under external physical impact, and the high solid content increases the covering power of the coating and reduces the number of construction. Alkali resistan...
