Abstract
Overview
ISO 11909:2025 - "Binders for paints and varnishes - Polyisocyanate resins - General methods of test" specifies general test methods for polyisocyanate resins and their solutions when used as binders in paints, varnishes and related products. This third edition updates the 2007 version and standardizes laboratory procedures for properties such as colour, viscosity, non‑volatile matter, flash point, density and isocyanate (NCO) content. The document includes a normative Annex A that details the quantitative determination of isocyanate groups.
