Durafine Coatings is a specialized manufacturer and distributor of high-performance process coatings, mold release agents, and industrial coatings serving the global rubber, automotive, tire, composites, polyurethane, engineered wood, and die-casting industries. In the rubber industry, Durafine Coatings offers a comprehensive range of mold release agents designed for compression molding, injection molding, transfer molding, rubber-to-metal bonding, silicone rubber molding, seals, gaskets, hoses, anti-vibration parts, conveyor belts, and other technical rubber products.
Durafine's release technologies are engineered to provide:
• Multiple releases per application
• Reduced mold fouling and cleaning frequency
• Improved surface finish and appearance
• Non-transfer performance
• Enhanced mold life
• Lower production downtime
• Consistent release across demanding molding conditions
Durafine Coatings' mission is to help rubber manufacturers achieve cleaner releases, superior part quality, longer mold life, and higher productivity through advanced release agent technology and dedicated technical support.
1. Water-Based Release Agents
The most widely used category for rubber molding today. They provide a clean release, low VOCs, and minimal mold buildup. Commonly used for:
• Compression molding
• Injection molding
• Transfer molding
• Rubber-to-metal bonding applications
2. Solvent-Based Release Agents
Used when:
• Fast drying is required
• High-temperature molding is involved
• Difficult compounds such as FKM, Viton, Vamac, or specialty elastomers are processed
3. Semi-Permanent Release Agents
These form a durable film on the mold and provide multiple releases per application, reducing downtime and mold cleaning. They are commonly used in:
• Automotive rubber parts
• Rubber-to-metal bonded products
• High-volume molding operations
4. Sacrificial (Conventional) Release Agents
These must be reapplied frequently—often every cycle or every few cycles.
Advantages:
• Easy to apply
• Lower initial cost
Disadvantages:
• More mold contamination
• Higher labor requirements
5. Silicone-Based Release Agents
Used for:
• Difficult-to-release compounds
• High-temperature molding
• Silicone rubber molding
Benefits:
• Excellent lubricity
• High thermal stability
• Good release performance
6. Silicone-Free Release Agents
Preferred when the molded part will later be:
• Painted
• Bonded
• Printed
• Glued
• EPDM Rubber
• NBR Rubber
• Natural Rubber (NR)
• SBR Rubber
• Silicone Rubber
• HNBR Rubber
• FKM / Viton Rubber
• Butyl Rubber, and more….
• Automotive Rubber Components
• Tire Manufacturing
• Seals and Gaskets
• O-Rings
• Industrial Rubber Components
• Rubber Hoses
• Medical Rubber Products
• Conveyor belts
• Aerospace Rubber Components, and many more….

Results & Benefits
Conclusion
Durafine's semi-permanent rubber release agent provided a step-change in productivity and quality for the customer’s molding operations. By eliminating the need for constant reapplication and reducing scrap, the customer achieved a more stable, scalable process—and significantly reduced total cost of production.
A high-output rubber components manufacturer—producing automotive and industrial seals, gaskets, and bushings—was struggling with frequent mold fouling, part surface defects, and high maintenance in their compression and injection molding lines. Their traditional release agent system required constant reapplication and led to inconsistent results.
The Problem
Key Challenges Faced
Durafine's Solution
Durafine introduced a semi-permanent release agent system tailored for rubber molding processes involving both natural and synthetic elastomers (EPDM, NBR, SBR, FKM, and silicone).
Solution highlights
They reduce sticking, mold cleaning frequency, downtime, and scrap rates during production.
The ideal release agent depends on the molding process, operating conditions, and product requirements.
Yes, high-performance release agents help minimize residue build-up and extend cleaning intervals.
Water-based release agents offer lower VOCs and safer handling while delivering effective release performance.
Improper release agent selection can impact secondary operations, making compatibility an important consideration.
Application frequency depends on the release agent type, molding conditions, and production volume.
Yes, Durafine Coatings supports manufacturers across Canada and the United States.
Yes, custom formulations can be developed to meet specific rubber compounds and production requirements.
