3784 fiberglass fabric is a heavy-weight industrial E-glass cloth with an 8-harness satin weave structure. It is designed for applications requiring high strength, heat resistance, flexibility, fire resistance, and coating compatibility.
Because of its smooth surface and heavy-duty construction, 3784 fiberglass cloth is commonly selected as a reinforcement base fabric for coated glass fabrics, welding protection materials, removable insulation systems, and high-temperature industrial barriers.
Heavy-duty fabric weight: Approx. 850 g/m² for high strength, durability, and industrial protection.
High temperature resistance: Fiberglass base fabric can withstand continuous temperatures up to approx. 550°C.
Fire-resistant and non-combustible: Suitable for welding protection, fire barriers, and thermal insulation systems.
8-harness satin weave: Smooth surface, good drape, high flexibility, and excellent coating compatibility.
Good electrical insulation: Suitable for thermal and electrical insulation applications.
Chemical and corrosion resistance: Performs reliably in many harsh industrial environments.
Ideal coating substrate: Can be coated with silicone, PU, PTFE, acrylic, graphite, vermiculite, or laminated with aluminum foil.
