CERAMIC COATING FOR COOKWARE: DURACERAM® TECHNOLOGY

DURACERAM® is the highest quality ceramic coating technology provided by GMMDL Vietnam, currently trusted and utilized by leading cookware manufacturers worldwide.

I. KEY BENEFITS OF DURACERAM®

DURACERAM® delivers outstanding performance characteristics compared to traditional PTFE coatings, including:

• Superior Scratch Resistance: Features an exceptionally high surface hardness rating of 7H to 9H (where H measures hardness).

• Outstanding Thermal Durability: Withstands extreme temperatures exceeding 900°F.

• Design Versatility: Enables the production of cookware in vibrant, diverse, and bright colors, offering more options to consumers.

II. FAQS ABOUT DURACERAM® TECHNOLOGY

For our clients and partners who want to understand the differences between ceramic and traditional PTFE coatings, we have prepared the following technical guide:

• What is a ceramic coating?

Ceramic coatings are inorganic in nature, meaning the base resin components within the formulation possess physical properties similar to natural ceramics. The critical chemical reactions that form the key components of the matrix are completed progressively during the application and high-temperature curing process.

• Why have ceramic coatings become so popular in recent years?

Ceramic coating technology has experienced rapid growth and adoption over the past five years. Previously, the non-stick market was dominated by PTFE. However, driven by the demand for product diversification and the exceptional benefits that ceramic coatings offer, this technology has gained immense trust from both manufacturers and consumers.

• Some say ceramic coatings became popular because PTFE coatings contain potential toxins. Is this true or false?

This is completely false. PTFE coating technology is entirely non-toxic to consumers and remains one of the safest and top-performing choices in the kitchenware manufacturing industry. GMMDL Vietnam confirms that both ceramic and PTFE coating technologies are safe for consumer health. Manufacturers can confidently use either material for different product lines depending on their specific goals.

• If both PTFE and ceramic are safe and effective, does ceramic still hold an advantage?

Absolutely. Ceramic coatings offer significantly higher heat resistance and scratch resistance than PTFE. Many consumers who cook frequently report preferring ceramic-coated cookware because it retains and distributes heat so efficiently that they only need a small amount of cooking oil. PTFE coatings, by contrast, act as passive thermal transfers and often require more oil.

Additionally, ceramic coatings can be formulated in vibrant, brilliant, and lively colors, offering a premium aesthetic that is simply not possible with color-restricted PTFE technology.

• Is it true that ceramic coatings do not release food as well as PTFE coatings?

Yes, this is true over the long term. However, during the first year of use, the non-stick release of a ceramic coating is outstanding, sometimes even outperforming PTFE.

The longevity issue with ceramic coatings typically arises because their non-stick properties are gradually stripped away by dishwasher use (due to harsh detergents and high water pressure). Therefore, for electrical cooking appliances and kitchenware where dishwasher use is not factored in, ceramic coatings perform exceptionally well, delivering performance that exceeds PTFE.

Why is DURACERAM® superior to other ceramic coating technologies?

DURACERAM® offers much higher scratch resistance and can withstand higher thermal limits. Furthermore, DURACERAM® is engineered for easier application on manufacturing lines compared to other standard ceramic coatings, optimizing production efficiency.
