Overview
ISO 18473-1:2015 establishes requirements and standardized testing methods for surface-treated nanoscale calcium carbonate in powder form, specifically for sealant applications. Developed by the International Organization for Standardization (ISO), this standard aims to harmonize expectations between producers and customers regarding the quality and performance of nanoscale calcium carbonate used as a functional pigment or extender in sealants. The document ensures clear communication across the supply chain and supports the reliable selection, testing, and application of these advanced materials in industrial sealant formulations.
Key Topics
ISO 18473-1:2015 covers several critical aspects necessary for the effective use of nanoscale calcium carbonate (NCC) in sealant applications:
Applications
The use of nanoscale calcium carbonate as a functional pigment and extender has broad industrial relevance, especially within the sealant sector:
Implementing ISO 18473-1:2015 leads to enhanced quality assurance, greater consistency in sealant performance, and decreased variability between batches. It also supports ongoing innovation in the field of nano-enabled sealant additives.
