Fiberglass mesh is used in a range of construction applications, including interior plaster reinforcement, external plaster reinforcement, ETICS and stone backing.
The coating system applied to the glass fiber mesh can influence the finished product's alkali resistance, water resistance, stiffness, flexibility and handling properties.
A water-based coating system for fiberglass mesh may be developed based on:
Different mesh structures may require different formulation approaches. A 90 g/m² mesh with a 10 × 10 mm aperture can have different coating requirements from a 160 g/m² mesh with a 4 × 5 mm aperture.
The coating system may include a suitable polymer binder together with wetting agents, defoamers, thickeners, crosslinkers and other formulation components.
The formulation and process parameters can be evaluated together through laboratory testing and production trials.
RUI CO provides water-based polymer solutions for industrial coating applications and can support formulation development based on specific mesh construction and processing conditions.
