ASTM D365 Standard Guide for Soluble Nitrocellulose Base Solutions
ASTM D365 provides guidelines for the preparation and testing of soluble nitrocellulose-based solutions, which are critical ingredients in the formulation of industrial coatings, printing inks, lacquers, and adhesives. It provides recommendations on best practices to achieve consistent levels of solubility, viscosity, and stability in nitrocellulose solutions, allowing manufacturers to tailor end performance properties to suit a specific end use. Key variables presented in the guide include nitrogen content, solvent selection, blending methods, and storage conditions, which can influence the behavior and quality of the final product. This method has been used as a blueprint in manufacturing operations, where a high-gloss, fast-drying, and durable finish is a significant consideration, promoting the dependable build and use of nitrocellulose-based finishes in business and industrial settings.

ASTM D365 Introduction
ASTM D365 is more of a guide than a test standard, aiming to help users develop an understanding of how to create, evaluate, and ensure the stability of nitrocellulose-based solutions. One resin commonly used is soluble nitrocellulose, which is produced by the nitration of cellulose to form film-forming resins. As a high-performing product in the printing, packaging, and automotive industries, it is dissolved adequately in organized solvents. It covers the main critical factors, including nitrogen content, solvent compatibility, viscosity range, and solution clarity. All these factors determine the performance during coating and bonding.
ASTM D365 Test Method
Scope
Covers preparation and handling of nitrocellulose-based solutions in organic solvents.
Focus Areas
Solubility behavior, viscosity adjustment, nitrogen content, appearance, and compatibility.
Viscosity Checks
Recommendations on measuring solution viscosity to match product specifications.
Solution Stability
Notes on storage conditions and testing for precipitation or gelling over time.
ASTM D365 Equipment and Sample Preparation
Specimen Details
Dissolve nitrocellulose in solvents such as ethanol, acetone, or acetate with specified nitrogen content.
Specimen Preparation
Nitrocellulose is added to the solvent under controlled temperature and movement to ensure gradual, complete dissolution.
Specimen Dimensions
Specific solutions contain 10–30% nitrocellulose by weight, depending on end-use requirements.
ASTM D365 Results and Interpretation
Defining solution behavior based on clarity, viscosity, and homogeneity, this method establishes a non-pass/fail standard for determining solution behavior. Good solubility is confirmed when the solution is homogeneous, the viscosity is constant, and the solution is homogeneous.

ASTM D365 Related Test Methods
ASTM D301 is used to test the Viscosity of nitrocellulose solutions, and ASTM E222 is used for nitrogen content determination.
ASTM D365 Applications and Industry Use
Soluble nitrocellulose is widely used in printing inks, automobile lacquers, wood finishes, and adhesives due to its film-forming and fast-drying properties. This method enables formulators and manufacturers to create stable base solutions, which are crucial for high-performance applications in the coating and packaging industries.
ASTM D365 Materials Commonly Tested
This method is used on industrial-grade nitrocellulose, both RS (regular solubility) and SS (special solubility), and is typically dissolved in a ketone-alcohol solvent mixture.
ASTM D365 Common Challenges and Troubleshooting
Very slow or, conversely, incomplete disintegration may mean a need for adjustment in movement speed, temperature, or solvent polarity. The guide also stresses that plasticizers and additives should not be inconsistent, as that can destabilize the solution.
ASTM D365 Safety and Best Practices
Nitrocellulose is an explosive, dry, inflammable compound. Be attentive when you work in a well-ventilated area and keep solutions in the approved containers.
