Water-based Clear Primer for Printing: Addressing Insufficient Ink Adhesion on Gold and Silver Cardboard The use of a water-based clear primer on gold and silver cardboard to resolve issues of insufficient ink adhesion is achieved primarily through the following mechanisms: Improving Surface Tension The surface of gold and silver cardboard is typically smooth and possesses low ...
Water-based varnishes are classified as eco-friendly products; the primary solvents used in their formulation are water and various alcohols, ensuring that their volatile components do not pollute the environment. The development of water-based varnishes has gained momentum in recent years, driven by the growing public demand for environmental protection. The process of applying varnish essentiall...
In flexographic printing, the performance of waterborne polymers and resin systems directly affects ink stability, color consistency, adhesion, and production efficiency. Traditional water-based inks may cause anilox roller clogging during long production runs, leading to unstable ink transfer and interrupted printing. In comparison, UV flexographic inks cure instantly under UV light, helping redu...
For coating and surface material applications, product performance depends on many real production factors. Laboratory testing is important, but actual customer feedback can provide more direct information about coating process, substrate condition, curing performance, adhesion, abrasion resistance, and final surface quality. Recently, the Sinograce Chemical team completed overseas customer visits...
PET bottles are widely used in food, beverage, personal care, and household packaging. Because PET has a relatively simple material structure compared with many multi-layer packages, it is often considered more suitable for recycling. However, the final quality of recycled PET does not depend on the bottle material alone. Labels and adhesives also play an important role in the recycling process. I...
The manufacturing of ceramic fiber paper plays a critical role in the performance of advanced thermal insulation materials used in high-temperature industries. The demand for advanced thermal insulation materials has increased significantly in high-temperature industries. Among them, ceramic fiber paper is widely used due to its excellent heat resistance, low thermal conductivity, and lightweight ...
In ceramic fiber paper production, the sheet does not always fail at the forming stage. Sometimes the wet sheet looks acceptable, but problems appear later during drying, winding, or cutting. For example, the paper may feel weak after drying. The edge may crack during slitting. Fine fiber dust may come off the surface. In continuous production, these small problems can quickly lead to material los...
Fiberglass mesh is a common reinforcement material widely used in external wall insulation systems, wall crack prevention, fiberglass mesh self-adhesive tape, and joint tape. For manufacturers, fiberglass mesh must not only have suitable weight and strength, but also maintain a stable mesh structure, good yarn positioning, and reliable processing stability. During fiberglass mesh production, warp ...
BOPP, PP, OPP, and PE films are widely used in flexible packaging, labels, and decorative applications due to their transparency, chemical resistance, and stable processing properties. However, printing on these films isn’t always straightforward. A printed surface may look fine initially, but problems can appear during tape tests, rewinding, die-cutting, or transport. Ink may peel, scratch, or lo...
If you are looking for water-based acrylic emulsion for adhesives, coatings, inks, textiles or packaging, here is what you should know. Water-based acrylic emulsion is widely used in modern industrial formulations because of its good film-forming performance, adhesion, transparency and environmental advantages. As more industries move toward water-based and low-VOC solutions, acrylic polymer emuls...
In packaging and label printing, a good printed surface is not only about bright color. It also needs to stay firmly on the substrate during rewinding, cutting, lamination, transportation and daily use. Some common problems are familiar to many ink manufacturers and printers: ink peels off after tape testing, the printed surface is easily scratched, color becomes uneven, or the ink layer loses str...
