Sustainable Artificial Leather Production with ORTEGOL® P Additives

Evonik supports the transition to safer and more sustainable artificial leather production with a dedicated application lab for polyurethane (PU) leather technologies. Our experts help manufacturers design high‑quality PU leather with improved efficiency, greater processing flexibility, and full technical support.

Today, more than 90% of artificial leather is still using DMF-solvent coagulation, an energy-intensive process that relies on hazardous chemicals. As the industry moves towards safer and more responsible production methods, Evonik provides solutions that enable DMF‑free, water‑borne, and solvent‑free PU coating technologies.

Two sustainable coating processes are rapidly gaining market share:

Water‑borne PU coatings: Use water instead of harsh solvents, significantly reducing VOC emissions and worker exposure.
2K solvent‑free PU coatings: Combine two reactive components directly on the fabric to form a durable coating without any solvent use.

These next‑generation processes lower environmental impact while delivering excellent softness, durability, and aesthetics.

We provide specialized additives tailored for both water‑borne and solvent‑free artificial leather technologies. For water-borne polyurethane dispersions, the ORTEGOL® P series supports smooth, uniform coatings through optimized foam stabilization, viscosity control, and dispersion performance. For 2K solvent‑free PU coatings, we offer specialized silicone surfactants and curing catalysts that improve leveling, surface quality, and coating consistency.

With these advanced additives, we enable manufacturers to reduce environmental impact while producing high‑quality, durable, and aesthetically consistent PU leather for fashion, automotive, furniture, and consumer applications.

Low‑VOC, Low‑GWP HFO Blowing Agents with POLYCAT® Catalysts

As the construction industry accelerates its shift toward low‑VOC, low‑GWP insulation materials, polyurethane spray foam remains one of the most effective solutions for achieving high energy efficiency. Applied onsite in liquid form, spray foam expands to fill gaps and conform to complex building geometries, delivering superior thermal insulation and long‑term durability.

With global regulations phasing out traditional HFC blowing agents, formulators are transitioning to environmentally friendly HFO (hydrofluoroolefin) blowing agents. Because HFOs behave differently in polyurethane systems, they often require specialized catalyst technology to ensure stable foam formation and consistent processing.

Our latest POLYCAT® catalysts, including POLYCAT® 206, are engineered specifically to support HFO‑blown polyurethane systems. These catalysts improve the compatibility, solubility, and reactivity profile of HFO formulations, helping maintain the foam’s rise profile, cell structure, and cure characteristics.

Key advantages of Evonik’s HFO‑optimized catalyst technology include:
• Improved stability and uniform foam formation in spray polyurethane foam (SPF) systems
• Better compatibility with HFO blowing agents compared to conventional amine catalysts
• Support for low‑VOC, low‑GWP, and regulatory‑compliant insulation solutions
• Balanced cream time, rise time, and cure profile for reliable onsite application
• Enhanced overall processing consistency and sprayability

By enabling a smoother transition to HFO technology, we help customers deliver more sustainable, high‑performance polyurethane insulation systems that meet evolving environmental standards and modern construction demands.
