In the field of fiber processing, water-based epoxy resin fiber sizing agents are triggering an innovative revolution and reshaping the industrial landscape. Traditional fiber processing has long been plagued by prominent pain points: severe fiber abrasion and breakage during high-speed weaving and drawing processes lead to obvious loss of finished product strength; poor interfacial compatibility between fibers and resin matrices causes delamination and insufficient mechanical properties of composite products, restricting the development of high-end composite materials.

Water-based epoxy resin fiber sizing agents break through bottlenecks relying on system advantages. Using pure water as dispersion medium, the product contains no volatile harmful solvents with low odor and low VOC, fully meeting the standards of green low-carbon production and environmental assessment, and matching the current industry trend of clean production transformation. Featuring excellent wetting and penetration capacity, it can rapidly and evenly coat single fibers and form dense flexible protective films on fiber surfaces, greatly reducing friction damage during drawing, twisting and weaving, effectively lowering filament breakage rate and improving the yield of raw fiber yarns.

Formulated with special organosilane coupling components, it builds a stable interfacial transition layer between fibers and resin substrates to strengthen two-phase bonding strength, and remarkably improve comprehensive mechanical properties including tensile, bending and impact resistance of composite materials. It is compatible with mainstream reinforcing fibers such as glass fiber, carbon fiber, basalt fiber and aramid fiber, widely applied in composite molding processes including winding, molding, pultrusion and sheet manufacturing. It helps enterprises stably produce high-end composite products with high strength, weather resistance and stability, pushing the whole fiber processing industry into a brand-new stage of green and high-performance development.
