Food Contact Safe Sealer

Food Contact Safe Sealer



Since 2019, Apexstone Amoy Marble and Granite, the manufacturer of TriaXtone products, have cooperated with NanoCare Deutschland AG based in Germany. We purchase the worlds top protection technology, nano silicon-based materials,  NanoFlex AG to apply to our products a standard sealer against food contact.


Due to material characteristics or a products complex shape the sealer NanoFlex AG cannot be used as an alternative layer for STAINLESS MARBLE

The difference between the two sealers are as follows:

FOOD CONTACT SAFE SEALER cannot completely resist stains, nor can it prevent corrosion by acid substances, such as lemon juice, wine or vinegar. It, however, plays a role in delaying there penetration, leaving time for you to clean up any spills. STAINLESS MARBLE can completely prevent the infiltration and corrosion of pollutants into the marble.

Please pay attention to the information displayed on our products during your selection. 


NanoFlex AG cannot completely prevent stains and corrosion, therefore why do we use such expensive materials on TriaxTone products?

First of all, STAINLESS MARBLE products that have the anti-corrosion treatment, the extra NanoFlex AG coating can effectively have a hydrophobic / water repellent ability to the surface. You can easily restore the finish of the product by flushing with water, without the need to wipe or scrub.

Secondly, after years of investigation, compared with other sealers in the market, NanoFlex AG , has been certified by authoritative organizations using the highest level of safety standards against extreme and stringent food contact without affecting the original texture of the marble. Other brands of sealer, may contain toxic substances within their manufacture, which are suitable for floor or wall marble applications that are not in contact directly with food.
