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...

What Should Be Considered When Modifying Water-Based Acrylic Resin
- 2026-07-03 17:12:10

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...

How to Choose the Right Water-Based Resin for Your Application
- 2026-08-05 17:59:28

Choosing a water-based resin should begin with the application, not with viscosity, solids content, or price. Products with similar technical data can behave very differently in production. A resin may work well on paper but show weak adhesion on plastic film. A coating may form properly under heated drying but remain tacky at room temperature. A low-viscosity polyurethane dispersion may look too ...
