Why Does Fiberglass Mesh Need a Setting Binder
- 2026-06-04 15:47:09
- admin
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 ...

Poor Ink Adhesion on BOPP and PP Films / A Top Coating Can Help
- 2026-06-05 18:37:46
- admin
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...

Why Ink Adhesion and Rub Resistance Matter in Packaging Printing
- 2026-06-10 17:41:44
- admin
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...

What Should Be Considered When Modifying Water-Based Acrylic Resin
- 2026-07-03 17:12:10
- admin
Adjusting a water-based acrylic resin formulation is rarely as simple as adding one new material. For example, increasing resin hardness may make the coating film more brittle. Reducing the glass transition temperature can improve low-temperature film formation, but it may also reduce heat resistance and blocking resistance. Increasing the amount of hydrophilic groups may improve emulsion stabilit...

Why Are Some Waterborne Polyurethane Dispersions Milky White While Others Are Translucent
- 2026-07-13 19:27:22
- admin
Waterborne polyurethane dispersions, commonly known as PUDs, may appear milky white, translucent, or slightly bluish in the liquid state. This difference is mainly related to particle size, particle size distribution, and how strongly the dispersed particles scatter visible light. In general, milky dispersions scatter more light, while finer dispersions allow more light to pass through. However, a...
