ASTM D564-87(2023) PDF

Overview

ASTM D564-87(2023), Standard Test Methods for Liquid Paint Driers, outlines the procedures for testing liquid driers used in paints and related coatings. The purpose of liquid paint driers is to accelerate the drying of oils, paints, varnishes, and inks. This ensures that coatings cure in a controlled and predictable manner, enhancing product performance and consistency. The standard provides comprehensive physical and chemical analyses for evaluating various types of liquid paint driers, especially those containing metals such as lead, cobalt, manganese, zinc, iron, calcium, and zirconium. Developed by ASTM International, this standard aligns with globally recognized principles and is approved for use by leading organizations.

Key Topics

• Scope of Testing: Specifies methods for assessing both the physical characteristics (appearance, stability, color, sediment, miscibility with oil) and chemical composition (metallic content) of liquid paint driers.
• Applicability: Focuses on liquid driers manufactured for use in decorative and industrial coatings.
• Quantitative Methods: Details test methods for determining the content of individual metals using ethylenediaminetetraacetic acid dihydrate (EDTA), with the caveat that these tests perform best with single-metal solutions.
• Physical Tests:
  • Appearance and clarity inspection
  • Sediment or suspended matter quantification
  • Color evaluation in accordance with established color scales
  • Stability analysis after exposure to varied temperatures
  • Nonvolatile matter measurement
  • Miscibility with linseed oil
  • Drying power determination using reference standards
• Chemical Tests:
  • Metal content determination (cobalt, lead, manganese, calcium, zinc, iron, zirconium, cerium, vanadium, rare earth metals) using specified ASTM test methods

Applications

ASTM D564-87(2023) is essential for:

• Paint and Coating Manufacturers: Ensuring consistency in product formulation and performance by verifying the quality and effectiveness of liquid driers.
• Quality Assurance Laboratories: Providing standardized test methods for routine inspection of incoming raw materials and finished products.
• Product Development: Assisting R&D teams in selecting optimal drier compositions for specific coating formulations, improving drying times and film integrity.
• Regulatory Compliance: Enabling manufacturers to demonstrate adherence to international benchmarks, ensuring products meet industry and safety standards.
• Comparative Testing: Facilitating side-by-side evaluation of drier performance, especially when validating new suppliers or alternative raw materials.
