Nanotechnology is a science capable of operating at the atomic level on a dimensional scale smaller than a micrometer. It enables the design and production of new materials — nanomaterials — used in the development of ultra-high-performance products and equipment. The plastics industry uses nanomaterials to create polymers with superior performance in terms of durability, mechanical strength, and aesthetic properties.

NanoMoldCoating® is a mold coating formulated using nanotechnology to facilitate part release for up to 300,000 cycles per application. It creates a colorless, non-toxic, hardened polymer film with a thickness of only 100 nanometers; therefore, it does not affect the dimensions of the finished parts.

NMC coatings are formulated from various chemical components that self-assemble when applied to a substrate. These components work together to form a microscopic nanometric mesh that prevents polymer molecules from coming into contact with the surface structures of the substrate. This network is vapor-permeable, allowing gases to escape from the substrate and enabling the coating to “breathe.”
Once applied, NanoMoldCoating completes its process in two phases. In the first phase, it anchors itself to the substrate by filling the microscopic peaks and valleys of the surface and bonding to the free molecules present on it. In the second phase, the coating cross-links during curing, forming the microscopic nano-mesh structure that provides hydrophobic and oleophobic properties.
This structure can withstand a wide range of temperatures without compromising the stability of the nano-mesh cross-linked structure or its adhesion to the substrate. NanoMoldCoating also has inherent flexibility, allowing it to expand and contract with the substrate within these temperature ranges without cracking or delaminating.

NMC is a semi-permanent hard coating. Unlike aerosol products, it does not migrate onto the surface of the molded part, eliminating the need for frequent reapplication. It does not affect the dimensional integrity of molded parts. In addition, it can be applied in-house, avoiding the need to send molds to external suppliers, resulting in significant time and cost savings.

  • HC™ Heat Cure e HCF™ Heat Cure FDA:

HC and HCF coatings are applied to the mold at room temperature in the workshop. After thoroughly cleaning the surface to be treated, the application can begin. Depending on the mold configuration, the supplied microfiber cloth or pad, or a small brush, may be used.
The HC coating comes in a single bottle containing the product, so it only needs to be shaken before opening.
The HCF coating comes in two bottles (A and B) that must be mixed together. Pour the entire contents of component B (small bottle) into the bottle containing component A (larger bottle), close the cap, and shake thoroughly for at least one minute to obtain a homogeneous mixture.
Proceed by pouring a small amount of product onto the pad or cloth and apply it to the surface in one direction. If applied correctly, the surface should appear damp but not wet, similar to wiping the surface with an alcohol-soaked wipe. If the pad or cloth dries out, add more product.
After applying the coating in one direction, apply a second coat in a perpendicular direction over the same area. The purpose of the second coat and the change in direction is to ensure complete surface coverage. Make sure there are no streaks or excess product build-up, as these may create sticky residues once cured.
Next, using a standard heat gun, begin the curing process. Set the heat gun to 290–320 °C. Holding the gun approximately 10–15 cm from the surface, apply heat using a slow, broad up-and-down motion for at least 10 minutes over the entire coated area.
Both HC and HCF coatings contain a UV tracer dye that becomes visible under black light, allowing you to confirm that the entire area has been coated.
If desired, a second coat may be applied for increased durability.
Once the operation is complete, cover the mold with a clean cloth to prevent dust from settling on the coating. Allow it to rest for at least three hours to ensure complete curing.

  • QC™ Quick Cure, QC Rubber™, QC Silicon™:

Quick Cure family coatings (Quick Cure, Quick Cure Rubber, and Quick Cure Silicone) are applied directly to the mold while it is in the press, controlling the surface temperature through the temperature control unit.
After thoroughly cleaning the mold, heat the surface to be coated to 50 °C.
Shake the coating bottle thoroughly before use and before any reapplication. Spray the product directly onto the mold surface or onto the microfiber cloth included in the kit. Lightly wipe the cloth in one direction, ensuring a thin and even layer is created. Immediately remove any excess build-up or streaks.
Once the entire area has been covered, reapply the coating, this time wiping in a perpendicular direction to ensure complete and uniform coverage.
After application, heat the mold to 115 °C and allow the coating to cure for 15–20 minutes before production.
If the mold surface cannot reach 115 °C, increase the curing time proportionally to the reduction in temperature.
Once cured, the mold is ready for use.

No. The coating thickness is approximately 100–200 nm, making it virtually immeasurable.

  • HC product: 12 months after opening.
  • HCF product: approximately 6 months after opening.
  • QC product: approximately 9 months after opening.
  • QCRU product: approximately 12 months after opening.
  • QCSI product: approximately 6 months after opening.

Reduces friction along the material flow path, improving part filling and compaction.

The service life depends on various factors, including:

  • Mold design
  • Molding parameters
  • Type of plastic material, fillers, and additives

In general:

  • Olefin-based materials and unfilled resins: 100,000–500,000 cycles
  • Filled materials: 10,000–100,000 cycles

In both cases, the return on investment is rapid thanks to reduced cycle times, fewer machine stoppages caused by parts sticking in the mold, and the reduction or elimination of traditional release agents.

The kinetic coefficient of friction ranges from 0.50 to 0.130 according to ASTM 1894 under laboratory conditions. What matters most, however, is the actual performance in the specific application. Customers switch to NMC for its superior release properties and flexibility of use.

PTFE coatings begin to degrade at 230–260 °C. HC and HCF products withstand temperatures up to 530 °C.

No. HC is resistant up to 530 °C and forms a nano-network engineered to expand and contract with the thermal expansion of the steel. Wear occurs microscopically over time.

The coating forms a covalent bond with the atoms on the substrate surface. On more porous materials such as aluminum, it can also penetrate the pores during the bonding process.

The coating forms a microscopic nano-network film with hydrophobic and oleophobic properties that protects the mold and facilitates the cleaning of material build-up caused by resin gases. In addition, it acts as a corrosion inhibitor and prevents oxidation.

Absolutely. The coating does not migrate onto the part surface and does not interfere with post-molding treatments.

Yes. The cured coating does not release the typical properties associated with silicone and does not migrate onto the part surface.

Yes, for the same reasons: it does not release silicone and does not migrate onto the part surface.

It adheres to virtually any metallic substrate, including:

  • All mold steels
  • Stainless steels
  • alluminium

For aluminum, a greater amount of product may be required compared to steel due to its higher porosity. Excellent results have also been achieved on epoxy resin molds.

Although originally designed for bare steel, it has also demonstrated good performance on chrome-plated surfaces as well as PTFE and nickel coatings.

No. In these cases, Min-Lube is recommended — a nanotechnology-based grease specifically designed for harsh environments and for the food and pharmaceutical industries. It is mineral oil-based, thickened with a proprietary calcium sulfonate complex, and enhanced with additives for thermal, oxidative, and mechanical stability.

The coating thickness is so minimal that it does not fill or alter surface textures.

The coating seals the surface with a microscopic hard layer. A slight improvement in surface finish or a minimal change in gloss level may occur.

If applied correctly, it does not alter the surface and may even improve its performance.

It is effective on all thermoplastics and on flexible thermosetting materials (polyurethanes, silicones, etc.). Performance depends on the mold, material, resin, and process parameters.


Yes, it has been successfully used on black rubber, silicone, TPE, TPU, and other compounds.

  • Injection molding.
  • Blow molding
  • Thermoforming
  • Extrusion
  • Fiberglass lamination
  • Epoxy molding

Research is continuously evolving for additional processes as well.

It is not suitable for sliding surfaces or threaded cores used with glass fiber-filled materials, which tend to abrade the coating. Threaded cores used with olefins and unfilled materials, however, are suitable.

No negative effects; it may even improve transparency.

The HCF coating is an amorphous cross-linked material that has been tested by internationally accredited independent laboratories and determined to be non-toxic. The HCF version is FDA-certified.

Cleaning is essential to prevent sealing contaminants into the surface. Oils, greases, protective agents, release agents, or residues trapped within the surface pores can interfere with the coating’s covalent bonding to the steel. It is therefore critical to thoroughly remove all residues from the surface to be coated.
Afterwards, moisten the white microfiber cloth included in the kit with a 100% pure solvent (ethanol, alcohol, acetone, or MEK solvent) to remove any remaining traces of cleaners or degreasers. The white cloth makes it easier to verify that the surface is completely clean.

The coating cross-links using atmospheric moisture as a catalyst. Moisture or oils introduced prematurely may compromise the curing process.

Yes, for HC, HCF, and QC coatings.

It is essential. The coating must fully cross-link in order to perform correctly.e.

No, it is better to dispose of them to avoid contamination.

Remove the spray nozzle and pump the product onto a cloth until the tube is completely empty.

Use brushes, cotton swabs, or micro-brushes..

No. Compressed air contains moisture: even a single drop of water can ruin the entire coating.

Surfaces coated with NanoMoldCoating should be cleaned regularly using NanoMold Cleaner, specifically formulated to remove contaminants without affecting the coating. The use of other, more aggressive cleaners may gradually damage the coating and reduce mold performance.

If it is necessary to remove the coating, simply spray the Remover onto the treated surface and allow it to soak in for a couple of minutes. The Remover is specifically formulated to break down the chemical bonds of the coating. Then scrub firmly to remove the coating.


Welding will damage the coating in the affected area. Reapplication will be necessary.

No. Any mechanical machining operation will damage the coating. A new application may be required.

Not recommended. They can mask the properties of the coating, and some petroleum-based products may render it ineffective.
