Rubber Mold Coating
DyCote-C Rubber Mold Coating Service
DyCote-C is a high-performance coating designed to improve release, wear resistance and surface quality in rubber molding. The industry needed a better technique for plating molds, and Hale Performance Coatings engineers responded by incorporating state-of-the-art electronics with innovative chemistry techniques to develop an alternative to the engineered chrome plating process. We produced chrome in an inert state of hardened metal, then paired it with a proprietary releasing agent to revolutionize the rubber molding process.
What is Rubber Mold Coating?
It’s a thin engineered surface treatment that’s applied to molds used in rubber processing. DyCote-C combines lubricating refractory materials with synthetic binders. The blend reduces sticking, improves mold longevity and enhances part finish by preventing adhesion and carbon buildup.
Rubber molds can degrade over time due to heat, chemical and abrasion exposure. Mold coatings act as release agents to prevent sticking during the casting process, making it easier to remove the finished product. That helps prevent damage and manage your operational costs.
Our Process
We complete a visual inspection to identify surface damage and contamination before removing previous coatings and residue with a solvent. The surface is buffed to create texture and support adhesion. We also apply a primer or conditioner depending on the cast.
Mold Surface Preparation
Spray or Drip Application
These applications create a uniform coating on the mold surface. Spraying allows for smooth layering and full coverage. Dripping involves pouring the DyCote-C coating over the mold surface. Both techniques may require multiple layers depending on the mold material.
Heat Curing to Bond the Coating
Heat curing enhances bonding and thermal resistance, improving the coating’s longevity. The process is completed in an oven to provide consistent heat to create a strong seal. We maintain a specific temperature throughout the procedure and allow each product to cool gradually.
Final Quality Inspection
Our staff carefully inspects the rubber mold for discoloration, mottled spots and pooled coating. Edges and undercuts are carefully evaluated for excess buildup. We also complete an adhesion test to ensure the coating doesn’t peel or flake.
How DyCote-C Enhances Rubber Molding Operations
Because DyCote-C is a durable, semi-permanent barrier, it provides a built-in release layer that prevents sticking. That reduces waste generation and optimizes your budget. Its heat-resistant qualities also make it last longer, so you don’t have to spend money on additional resources.
Other advantages include:
Reduced need for release agents: Whether you’re casting metal, rubber or composite materials, rubber mold coating can prevent residue buildup, eliminating the need for chemical release products. That means cleaner casting and easier maintenance.
Minimized cleaning cycles: The non-stick texture of DyCote-C allows for effective removal. That keeps the mold surface cleaner longer without the need for abrasive chemicals.
Consistent cycle times: Precise removal prevents part sticking and operational delays. You won’t have to fight with stuck components, repair damaged surfaces or reapply coatings between cycles.
Improved part appearance: Smooth rubber mold coatings result in high-quality casting and prevent blemishes, air bubbles and tearing. The result is more consistent finishes, fewer rejects and quicker application.

FAQs
How long does the coating last?
One coating typically lasts 25 to 100 casting cycles, depending on the material, mold design, surface preparation and temperature.
Can I reapply DyCote-C?
Yes. You should reapply rubber mold coating if you notice thinning or cast components sticking during release. It’s suitable for spot and full reapplication.
Does it affect molded part dimensions?
DyCote-C has minimal effect on mold design but can present issues if allowed to build up over time without proper cleaning.
What mold materials are compatible with (steel, aluminum, etc.)?
It’s compatible with natural and synthetic rubber, aluminum, steel, plaster, ceramic and carbon-based materials.
