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 ...

Why Do Fabric Coatings Crack After Stretching
- 2026-06-24 17:17:23
- admin
A fabric coating may look smooth after drying but develop cracks, whitening or peeling when the material is stretched or folded. In many cases, the problem comes from the balance between film hardness, adhesion and elasticity. The film is too hard A hard coating film can provide good surface strength, but it may not be flexible enough for stretch fabrics. When the fabric moves, the coating must mo...

Why Are Some Waterborne Polyurethane Dispersions Milky White While Others Are Translucent
- 2026-07-16 15:53:46
- 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...

How Do You Select the Right Tg for a Water-Based Acrylic Label Adhesive
- 2026-07-22 18:56:18
- admin
When formulating a water-based acrylic pressure-sensitive adhesive for labels, Tg is usually one of the first parameters we set. It indicates whether the dry adhesive film will behave relatively soft or firm at a given temperature and influences initial tack, peel adhesion, holding power, low-temperature performance and adhesive ooze. However, Tg alone does not determine whether an adhesive is sui...
