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.

Our product portfolio includes:

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

Durafine release agents are compatible with the following polymer compounds:

• EPDM Rubber
• NBR Rubber
• Natural Rubber (NR)
• SBR Rubber

Durafine Case Study

Increasing Efficiency in Rubber Molding with Durafine Semi-Permanent Release Agents

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

  • Frequent reapplication of release agents after every 1–2 cycles
  • Mold build-up causing defects, cleaning downtime, and increased scrap
  • Release agent transfer to molded parts, leading to post-processing issues (e.g., bonding, painting)
  • Operator exposure to high-VOC solvents in manual application areas
These problems created production delays, increased labor costs, and limited capacity for scale-up.

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

  • Water-based, semi-permanent release agent
  • Forms a thin, heat-cured barrier that allows multiple releases (5–20 cycles)
  • Leaves no transfer on molded parts—ideal for bonding or painting
  • Low-VOC, non-flammable, safer for workers and compliant with global regulations
  • Compatible with compression, injection, and transfer molding

Why Manufacturers Choose Durafine Coatings?

  • Industry Expertise
  • Custom Formulation Capabilities
