Proven Coating for Drinkware
Dongke Electric Heating has years of mass production experience with nanocoatings for stainless steel drinkware. Our company started in 2017. Our R&D team developed the coating technology independently. We own all the intellectual property rights. We produce 10,000 cups per day. Our coating process produces zero VOC emissions. The coating also performs well on cup inner surfaces. It has strong adhesion and long-term durability. Leading cup brands in China have used our coating in stable mass production.

A Reliable Mug for Your Bag

The Leak-Proof Insulated Mug is designed for daily carry. It has a 304 stainless steel inner layer and a 201 stainless steel outer shell. The double-wall vacuum design keeps drinks hot or cold for 6 to 12 hours. The PP push lid features an improved sealing structure. It opens and closes easily. It prevents leaks when carried in your bag. The inner surface has our inorganic hydrophilic coating. A common problem with regular mugs is that tea and coffee stains build up on the inner wall over time. They can cause unpleasant odors and discoloration. Normal cleaning methods cannot completely remove them. Our coating works differently. It creates a smooth, low-adhesion layer on the metal surface. Water fully wets the coated surface and forms a film that carries stains away. The Leak-Proof Insulated Mug stays clean with just a water rinse. No heavy scrubbing is required.
Light and Easy to Carry
This mug has a capacity of 12 oz, which is about 355 ml. It is lightweight and compact. It fits in your pocket or a small bag. The coating also helps inhibit bacterial growth on the inner surface. Colors are available in 14 options, including white, black, ivory, violet, gold, skin tone, dark green, yellow, dark blue, lake blue, off-white, gray, blue, and light purple. This covers a wide range of styles. This product was launched in 2024. It has already been tested in the market. We offer OEM and ODM services. We support logo and packaging customization.
