ASTM D5137-07(2021) PDF

Overview

ASTM D5137-07(2021): Standard Specification for Hexyl Acetate provides a comprehensive framework for ensuring the quality and consistency of hexyl acetate used as a high boiling solvent. This standard is crucial for industries that formulate lacquers, automotive coatings, maintenance paints, and other related coatings. ASTM D5137 outlines sampling methods, property requirements, and test procedures to maintain the performance and safety of products containing hexyl acetate.

Key Topics

• Material Specification: Defines required physical and chemical properties for hexyl acetate including acidity, specific gravity, color, distillation range, electrical resistivity, ester value, and water content.
• Test Methods: Specifies standardized testing protocols for each required property, referencing established ASTM test methods to guarantee reliable and accurate results.
• Sampling and Packaging: Details on appropriate sampling practices and packaging requirements to preserve the integrity and safety of hexyl acetate during transport and storage.
• SI Units Compliance: All specifications are provided in SI units, ensuring international consistency and compatibility.
• Conformance and Rounding: Clarifies how specification limits and measured values should be rounded off in accordance with ASTM Practice E29 for data consistency.

Applications

Hexyl acetate formulated in accordance with ASTM D5137 is widely used as a solvent in several critical applications:

• Lacquers and Coatings: Acts as an efficient tail solvent in clear and pigmented lacquers, promoting optimal drying times and surface finish.
• Automotive Finishes: Ensures high performance and long-term durability of automotive coatings by providing controlled evaporation rates and compatibility with other solvent components.
• Maintenance and Industrial Paints: Facilitates the formulation of durable maintenance paints suitable for a range of surfaces, resisting weathering and chemical exposure.
• Specialty Coatings: Supports the production of bespoke coatings where solvent purity, volatility, and compatibility are essential for application-specific requirements.

By adhering to ASTM D5137, manufacturers and formulators can ensure product quality, regulatory compliance, and safe performance in end-use environments.
