High Quality Sizing and Emulsion for Basalt Fiber
1. Who We Are
UTEK Composites is a chemistry development leader and a premier supplier of sizing agents, binders, and emulsions for the fiberglass, carbon fiber, and—most notably—basalt fiber industries. While our heritage lies in glass fiber solutions, the rapid global expansion of high-performance basalt fiber applications has driven us to invest heavily in specialized R&D. Today, our products are certified by manufacturers across Europe, Asia, and the Americas, confirming that UTEK Composites delivers world-class, cost-effective chemistry.
2. Our Flagship Product: Epoxy Emulsion 8828 for Basalt Fiber
A key challenge in basalt fiber production is applying a water-based epoxy resin emulsion that ensures uniform coating, strong adhesion, and thermal stability. Until recently, most basalt fiber producers had to rely on expensive European imports. To fill this gap, we developed our own emulsion—internal code 8828—through rigorous lab work and pilot trials.
The results speak for themselves:
· Superior film formation – creates a smooth, defect-free surface on basalt fiber filaments.
· Excellent thermal stability – withstands the high-temperature processing inherent to basalt fiber manufacturing.
· Consistent adhesion – improves interfacial bonding with subsequent resin matrices.
After extensive online testing in real basalt fiber production lines, 8828 has proven to fully match—and in some parameters outperform—the European benchmark. Multiple basalt fiber mills have now switched to 8828, achieving significant cost savings without sacrificing quality. This success confirms that UTEK Composites is a reliable, high-tech alternative to traditional Western suppliers for all basalt fiber-related chemical needs.
