GB/T 33312-2016 stipulates the general test method for paint-based polyisocyanate Resin for Paints and varnishes. The standard specifies the scope of application, covering the determination methods of many key indicators such as density, viscosity, non-volatile-matter content, isocyanate group content, etc., and specifies the equipment, reagent materials, test procedures and result calculation in detail. It provides a unified standard for scientific and accurate detection of polyisocyanate Resin performance, and helps to control the mass of paint base and Coating product performance.
