Non-Transfer High-Temperature Water-Based Mold Release Agent Lubekote 9440A for Silicone Fluorine Rubber

Non-Transfer High-Temperature Water-Based Mold Release Agent Lubekote 9440A for Silicone Fluorine Rubber

Lubekote 9440A is an advanced water-based semi-permanent mold release agent specifically engineered for the most demanding silicone and fluorine rubber molding applications where high temperatures, aggressive chemical environments, and strict non-transfer requirements converge. This premium formulation features a unique non-transfer polymer system that creates an exceptionally durable, chemically resistant release barrier on mold surfaces while absolutely preventing any migration of release agent residues to molded part surfaces. This characteristic is critical for high-value silicone and fluorine rubber components used in aerospace, medical, semiconductor, and food processing applications where even trace levels of surface contamination are unacceptable and can lead to part rejection, functional failure, or regulatory non-compliance.

The high-temperature stability of Lubekote 9440A sets it apart from conventional water-based release agents that typically degrade or lose effectiveness at elevated mold temperatures. With proven performance at continuous mold surface temperatures up to 250°C, this product maintains its release integrity in the extreme thermal environments characteristic of fluorosilicone (FVMQ) and fluoroelastomer (FKM) processing. The exceptional abrasion resistance of the cured release film ensures consistent performance even in molding applications involving abrasive filler compounds or high-pressure injection processes, delivering the reliability that manufacturers of critical-performance elastomer components demand from their process consumables.

• Non-Transfer Guaranteed Formula: The advanced crosslinking polymer system creates an impenetrable release barrier that absolutely prevents migration of release agent residues to molded part surfaces, essential for contamination-sensitive applications in medical, aerospace, and semiconductor industries.
• High-Temperature Stability Up to 250°C: Maintains full release performance and coating integrity at continuous mold surface temperatures that cause conventional water-based release agents to degrade, blister, or lose effectiveness.
• Excellent Abrasion Resistance: The cured release film resists mechanical wear from abrasive filler compounds and high-pressure injection molding processes, delivering consistent multi-cycle performance without coating breakdown or localized release failure.
• Water-Based Environmentally Friendly: Solvent-free formulation eliminates the risk of solvent-induced swelling or degradation of sensitive silicone and fluorine rubber compounds while providing a safer, cleaner production environment.
• Superior Surface Finish Quality: Delivers an exceptionally smooth, defect-free surface on molded silicone and fluorine rubber parts that meets the stringent aesthetic and functional requirements of high-value application sectors.
• Extended Mold Cleaning Intervals: The non-stick, chemically resistant coating prevents mold fouling and residue accumulation, dramatically extending the time between mandatory mold cleaning and maintenance shutdowns.
• Broad High-Performance Elastomer Compatibility: Proven effectiveness across silicone rubber (VMQ), fluorosilicone rubber (FVMQ), fluoroelastomer (FKM), perfluoroelastomer (FFKM), and hydrogenated nitrile rubber (HNBR) compounds.
