Hyperbranched Alkyd Resin Synthesis and Polyurethane Coating Performance

A novel hyperbranched alkyd resin synthesized from castor oil fatty amide polyol and pyrometallic anhydride. The polyurethanes derived from these resins were applied as coatings on mild steel and wood substrates. Performance was evaluated through cross cut adhesion, impact resistance, gloss, scratch hardness, chemical resistance, electrochemical properties, thermal analysis, and surface morphology.

Use Cases

• Predict coating performance metrics like scratch hardness based on resin synthesis parameters.
• Analyze the relationship between chemical properties (acid/hydroxyl values) and thermal stability of polyurethane coatings.
• Correlate surface morphology from SEM images with measured coating properties like adhesion and chemical resistance.

Strengths

• The resin and coatings were characterized using multiple techniques: size exclusion chromatography, NMR, FTIR, thermogravimetric analysis, and scanning electron microscopy.
• Coating performance was evaluated across a range of mechanical, chemical, and electrochemical tests.

Limitations

• Row count and dataset scale are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred from the description.
