Overview
SIST EN ISO 6744-3:2004 is an international standard developed by the International Organization for Standardization (ISO) and adopted by CEN, focusing on the determination of unsaponifiable matter content in alkyd resins used as binders for paints and varnishes. This standard provides a precise analytical method for quantifying unsaponifiable components-a critical quality parameter affecting the performance and durability of alkyd resin binders.
This part (Part 3) of the ISO 6744 series must be used in conjunction with ISO 6744-2, which outlines the preliminary steps for sample preparation and phthalic anhydride content determination. The methodology is not applicable to modified alkyd resins, ensuring its relevance primarily for conventional alkyd resin products.
Key Topics
Scope and Applicability
Defines a standardized chemical analytical procedure to measure unsaponifiable matter in alkyd resins specifically for unmodified resin types.Analytical Principle
The process involves drying the saponified resin filtrate (prepared as per ISO 6744-2) and performing solvent extraction-using either diethyl ether or light petroleum ether-to separate and isolate the unsaponifiable matter. The isolated residue is weighed to calculate the percentage present.Reagents and Equipment
Utilizes high purity reagents such as peroxide-free diethyl ether, light petroleum ether (30 °C to 50 °C boiling range), potassium hydroxide solution, acetone, and ethanol. Laboratory apparatus includes separating funnels, distillation or rotary evaporators, and drying ovens.Methods Provided
The standard details two extraction techniques:- Diethyl ether method: Preferred but may require steps to break emulsions.
- Light petroleum method: Alternative method beneficial when emulsions complicate the diethyl ether extraction.
Calculation of Results
The unsaponifiable matter content is calculated as a percentage by weight, based on the original sample mass determined with ISO 6744-2.Reporting Requirements
Test reports must include reference to the standard, product details, test results and method, deviations if any, and testing date.
Applications
Quality Control in Paints and Varnishes Manufacturing
Ensures the purity and compositional consistency of alkyd resin binders, which directly influence the drying time, gloss, hardness, and chemical resistance of coatings.Research and Development
Assists R&D labs in characterizing new alkyd resin formulations to meet desired specifications and performance parameters.Regulatory Compliance and Industry Standards
Facilitates compliance with industry-wide quality criteria, supporting product certification and market acceptance across European and international markets.Material Purity Assessment
Helps in identifying impurities and unsaponifiable substances that could affect the physical or chemical stability of alkyd resin-based coatings.
Related Standards
For comprehensive evaluation and analysis of alkyd resins, SIST EN ISO 6744-3:2004 is used alongside other parts of the ISO 6744 series:
- ISO 6744-1:1999 – General Methods of Test for Alkyd Resins
- ISO 6744-2:1999 – Determination of Phthalic Anhydride Content (Preliminary step for EN ISO 6744-3)
- ISO 6744-4:1999 – Determination of Fatty Acid Content
- ISO 15528 – Sampling of Paints, Varnishes, and Raw Materials
Additionally, ISO 3696:1987 addresses water quality specifications for laboratory analysis, ensuring reagent and sample consistency.
