Overview
ASTM D6887-03(2020), titled "Standard Test Method for Testing Alkyd Compatibility with Resin or Resin Solutions," provides a systematic procedure to evaluate the compatibility of alkyds with specific resins or resin solutions. This standard is widely used in the lithographic ink industry to ensure that combinations of alkyds and resins result in stable, homogenous mixtures essential for optimal performance in pigment wetting and ink vehicle applications. Determining compatibility is crucial, as incompatibility can lead to several issues, including loss of gloss, decreased color strength, rheological problems, and grinding difficulties in pigment bases.
Key Topics
- Purpose: Provides a test method for determining the degree of compatibility between alkyds and resins or their solutions, especially for use in lithographic ink vehicles.
- Procedure Overview:
- Specific resin-to-alkyd ratios are prepared and mixed in a controlled environment.
- Mixtures are heated and then cooled to assess compatibility based on clarity and stability.
- Observations are made at two intervals: after 30 minutes and after 24 hours.
- Compatibility Definitions:
- Compatibility: A resin and solvent mixture forms a clear, homogeneous, and stable solution.
- Incompatibility: The mixture fails to form a clear, stable solution.
- Significance: This test helps manufacturers avoid product failures caused by incompatible ink vehicles, leading to higher quality outputs and efficient pigment dispersion.
- Safety and Compliance: Users must establish appropriate safety, health, and environmental practices, ensuring alignment with local regulations.
Applications
ASTM D6887-03(2020) is especially relevant for:
- Lithographic Ink Manufacturing: Key for manufacturers selecting alkyd and resin (particularly hydrocarbon resin) blends for lithographic printing inks.
- Pigment Wetting Applications: Ensures effective wetting and dispersion of pigments, resulting in improved color consistency and strength.
- Quality Control in Coatings: Enables quality assurance teams to verify and document the compatibility of new resin/alkyd formulations before mass production.
- Product Development: R&D teams use this standard to innovate and refine formulations in response to evolving industry needs or regulatory requirements.
- Technical Assessments: Provides a consistent method for evaluating product performance and troubleshooting blending issues between alkyds and resin solutions in aliphatic solvents.
Related Standards

- Other ASTM Ink and Coating Standards: Ensures comprehensive evaluation when paired with standards covering pigment dispersion, gloss, and rheology.
- WTO TBT Principles: This standard was developed in compliance with internationally recognized principles for standardization, as set out by the World Trade Organization Technical Barriers to Trade Committee.
Practical Value
Implementing ASTM D6887-03(2020) helps ink and coating formulators to:
- Reduce the risk of costly formulation errors by systematically screening resin-alkyd compatibility.
- Maintain product excellence in color reproduction, gloss, and stability, critical in lithographic printing.
- Uphold international quality assurance by referencing a widely recognized ASTM test method.
- Streamline compliance with both industry best practices and regulatory requirements related to chemical safety and standardization.
