Abstract
This study investigates the migration behavior of Na2O-B2O3-SiO2 glass-ceramic coatings under different exposure durations. Sinter-crystallization at 830 °C for 4.5 min transforms the glass into a crystalline phase. Coatings were immersed in 3% acetic acid solutions for durations ranging from 15 to 960 min. Chemical migration was measured using ICP-MS analysis, while SEM and surface profilometry assessed surface morphology and roughness. Coatings remained compliant with ISO 4531:2022 food-contact standard, even after 960 min. Dissolution of alkaline network modifiers initially increased roughness, which then returned to the initial value. This research provides insights into the stability and applicability of glass-ceramic coatings for long-term use in food-contact surfaces, contributing to the field of surface coatings and food safety.
期刊介绍：
The aim of the journal is to provide a respectful outlet for ''sound science'' papers in all research areas on surfaces and interfaces. We define sound science papers as papers that describe new and well-executed research, but that do not necessarily provide brand new insights or are merely a description of research results.
Surfaces and Interfaces publishes research papers in all fields of surface science which may not always find the right home on first submission to our Elsevier sister journals (Applied Surface, Surface and Coatings Technology, Thin Solid Films)
