Target Industrial Applications
Electrical Insulation: High-voltage casting, insulators, and electrical coil impregnations where controlled ionic content reduces electrical tracking risks.
Electronic Encapsulation & Potting: Protecting sensitive microelectronics, sensors, and transformers with low moisture absorption and minimal ionic migration.
Electronic Adhesives & Sealants: Structural bonding for semiconductor packaging and electronic components requiring high long-term reliability and low ionic contamination.
How to Select the Right Low-Chlorine Grade
Choosing a low-chlorine epoxy resin requires evaluating multiple technical parameters beyond a single chlorine value:
Define Chlorine Limits:
Specify your threshold for hydrolyzable chlorine, total chlorine, or inorganic chloride and the required analytical test method. (Note: Hydrolyzable and total chlorine measure different parameters and are not interchangeable).
Match Formulation Stoichiometry:
Check the Epoxy Equivalent Weight (EEW) and viscosity against your hardener system (such as anhydride or amine curing agents) to maintain processing windows and mixing behavior.
Validate Prior to Production:
Review the technical data sheet (TDS), request a representative batch COA, and test trial samples within your production environment before mass purchasing.
Packaging, Storage & Supply
Standard Packaging: 200kg iron drums, IBC totes, or customized export containers.
Storage Recommendations: Store in a cool, dry, well-ventilated area away from direct sunlight and moisture. Keep containers tightly sealed.
Shelf Life: Typically 12 months from the manufacturing date when stored under recommended conditions.
Quality Assurance & Manufacturing Capability
Operating under strict quality control standards to ensure batch-to-batch consistency.
Quality Documentation:
Each production batch is rigorously tested, accompanied by a comprehensive Certificate of Analysis (COA) and batch-specific chlorine test results.
Export Capabilities:
Stable supply chains and flexible export arrangements (FOB, CIF, CFR terms available) tailored to international chemical buyers.
Frequently Asked Questions
Q: What is low-chlorine liquid epoxy resin?
A: It is a specialized liquid epoxy resin manufactured to meet strict residual chlorine limits. It is designed for applications where ionic contamination must be minimized to ensure long-term electrical reliability and performance.
Q: What is the difference between hydrolyzable chlorine and total chlorine?
A: Total chlorine measures the overall chlorine content in the resin according to the specified analytical method. Hydrolyzable chlorine measures only the fraction determined by a hydrolysis-based test. These two parameters measure different properties and are not interchangeable.
Q: Can low-chlorine epoxy resin be customized for specific formulation requirements?
A: Yes. Depending on the target application, resin grades can be tailored regarding epoxy equivalent weight (EEW), viscosity, and maximum allowable hydrolyzable or total chlorine limits. Technical requirements should be reviewed prior to grade selection.
