Coating Add-On Control in Fiberglass Mesh Production

The dry coating add-on is an important process parameter in the production of coated fiberglass mesh.

The coating add-on can affect the finished mesh's:

• Stiffness
• Flexibility
• Coating coverage
• Water resistance
• Handling properties
• Product weight

The required add-on may vary according to the mesh construction and end-use application.

Several process parameters can influence the final coating add-on:

1. Coating-bath solids content
2. Bath viscosity
3. Wet pick-up
4. Coating method
5. Production line speed
6. Drying temperature
7. Residence time

These parameters should be evaluated as part of the complete coating process.

A suitable balance between coating quantity and final product requirements can support consistent production and help manage material consumption.

RUI CO can assist in evaluating water-based coating systems according to specific production conditions and product requirements.
