Advanced Solvent-Based Polyurethane (PU) Technology
In high-performance textile systems, coating chemistry defines the limits of durability and reliability. eTek’s® solvent-based polyurethane (PU) coating system is engineered for demanding industrial and outdoor applications where long-term performance is essential. This system leverages a proprietary solvent-dissolution phase that fully integrates the polyurethane matrix prior to application. As solvents evaporate during curing, the coating forms a dense, continuous film that bonds directly to the substrate. The result is a cohesive structure that becomes part of the fabric itself, not just a surface layer.
Solvent-based PU systems use organic solvents to fully dissolve the polyurethane resin prior to application. As the solvent evaporates during curing, it leaves behind a dense, continuous film that bonds directly to the substrate. This process allows the coating to integrate with the fabric structure rather than simply sitting on the surface.
The eTek® Advantage
eTek's® solvent-based PU stands apart through complete polymer integration before film formation. This controlled process produces a uniform, tightly packed coating architecture during solvent evaporation, delivering enhanced mechanical strength and consistent surface performance.
Performance benefits include:
• Long-term water resistance under extended exposure
• Increased abrasion resistance in high-wear environments
• Improved tensile and tear strength due to strong substrate adhesion
• Resistance to oils, fuels, and industrial cleaning agents
• Improved adhesion to eTek® DWR Nylons and eTek® Solution-Dyed Polyesters
• Improved cold crack compared to water-based coatings
Engineered for demanding environments
eTek® solvent-based PU coatings are developed for applications that require durability and environmental resilience.
Common applications include:
• Marine covers and enclosures
• Awnings and outdoor structures
• Industrial equipment covers
• Transportation and automotive materials
• Heavy-duty tarps and protective textiles
