Water-Based High-Temperature PU Foam Mold Release Agent for Automotive Steering Wheel Polyurethane Foaming

Lubekote PU-SW series is a premium water-based semi-permanent mold release agent specifically engineered for automotive steering wheel polyurethane foam molding applications. This advanced release technology addresses the unique challenges of high-temperature PU foaming processes where mold surface temperatures can exceed 180°C. The formulation creates a durable, chemically bonded release film that delivers consistent, flawless demolding performance while imparting a perfect surface finish to the molded steering wheel components. Unlike conventional wax or silicone-based release agents that can leave residues and compromise subsequent bonding or coating operations, this water-based solution provides a clean, non-transferring release that preserves the dimensional accuracy and aesthetic quality demanded by automotive OEM specifications.

Developed through extensive collaboration with leading automotive parts manufacturers, Lubekote PU-SW release agent has been optimized for both open-pour and closed-mold PU foaming systems commonly used in steering wheel production. The environmentally friendly water-based formulation eliminates hazardous solvent emissions, aligning with the automotive industry’s increasing focus on sustainable manufacturing practices. Its semi-permanent coating characteristic significantly reduces the frequency of mold preparation interventions, enabling manufacturers to achieve higher production throughput while maintaining consistent part quality across extended production runs. The product is fully compatible with both MDI and TDI based polyurethane foam systems used in steering wheel manufacturing.

• Water-Based Eco-Friendly Formula: Solvent-free composition eliminates VOC emissions from the molding environment, ensuring compliance with stringent automotive industry environmental standards and improving workplace safety for mold operators.
• High-Temperature Performance: Engineered to maintain release integrity at mold surface temperatures up to 200°C, providing reliable demolding performance in the demanding thermal conditions characteristic of PU foam steering wheel production.
• Perfect Surface Finish: Delivers an exceptionally smooth, defect-free surface on molded steering wheel components that meets the exacting aesthetic and tactile quality standards of automotive interior parts.
• Non-Transferring Clean Release: Does not migrate to the molded PU foam surface, ensuring full compatibility with subsequent leather wrapping, painting, coating, and adhesive bonding processes without additional cleaning steps.
• Minimal Mold Build-Up: The advanced polymer formulation resists accumulation on mold surfaces over repeated cycles, significantly extending the intervals between mandatory mold cleaning and maintenance operations.
• Semi-Permanent Multi-Cycle Durability: A single application provides reliable release across multiple molding cycles, dramatically reducing mold preparation time and per-unit release agent consumption costs.
• Easy Application Process: Simple spray application with rapid water evaporation and film formation, requiring no specialized equipment or curing procedures that would slow down production cycle times.
