Water-based release agents for polyurethane steering wheels: a clean, high-performance solution 24/11/2025

Using an unsuitable release agent when molding polyurethane automotive steering wheels can lead to numerous non-conformities:

• Greasy deposits on molded parts
• Inconsistent appearance from one batch to another
• Premature mold wear
• Aesthetic flaws (unwanted shine, lack of uniformity)

In the automotive sector, where quality and repeatability requirements are strict, these issues are unacceptable. Manufacturers are therefore seeking clean, easy-to-integrate solutions that respect workplace safety and the production environment.

Water-based formulations meet these needs: they limit volatile emissions, reduce risks for operators, and make equipment cleaning easier. These solutions are fully aligned with a responsible chemistry approach.

Two references, two finishing levels

The water-based release agents: 1801/167 and 1801/168, share a common water-based formula, designed for smooth release without greasy residue and excellent compatibility with PU formulations for steering wheels.

Release agent 1801/167: delivers a uniform semi-matte finish, ideal for classic finishing standards. It combines efficiency, process stability, and clean molds, even at high production rates.

Release agent 1801/168: wax-enriched version for a slightly more matte effect and easier demolding on complex parts or those with high visual requirements

The choice between the two depends mainly on the desired finishing level by the manufacturer or the type of mold used. Their compatibility also allows manufacturers to switch from one to the other based on production batches, without major disruption to the process.

Developed and manufactured in France, Keck 1801/167 and 1801/168 release agents have been tested under real conditions on PU steering-wheel molding lines.

They are:

• Easy to apply, either manually or through automated systems
• Stable over long production cycles
• Compatible with complex mold geometries
• Non-classified as flammable, for simplified storage

These technical advantages make them valuable solutions for suppliers and automotive parts manufacturers aiming for consistent productivity, flawless finishing, and more responsible chemistry.
