1. Product Appearance Changes
AC-1830 may appear as a light yellow to yellow paste or solid at different temperatures, which is a normal physical phenomenon and does not affect performance. If the product shows obvious discoloration, separation, odor, or other abnormalities, it may be due to improper storage (such as high temperature exposure, moisture, or contact with strong oxidizers), leading to deterioration. Stop using immediately and contact the technical team.
2. Dissolution and Dispersion Issues
Stearylamine Polyoxyethylene Ether AC-1830 is a high molecular weight nonionic surfactant. When dissolving, it is recommended to use warm water at 40~60°C and add slowly under stirring to avoid clumping from adding a large amount at once. If dispersion in water is poor, appropriately increase the water temperature or extend the stirring time. When compounding with anionic, cationic, and other nonionic surfactants, pay attention to the order of addition to achieve optimal synergy.
3. Unsatisfactory Application Results
If the effect is not as expected in scenarios such as textile leveling, pesticide emulsification, or metalworking lubrication, first check: ① Whether the product dosage is within the recommended range (the optimal addition amount should be determined through experiments based on the specific process); ② Whether the pH value and hard water conditions of the formulation system are compatible (AC-1830 has excellent resistance to acid, alkali, and hard water, but extreme conditions still need verification); ③ Compatibility of other components in the compounding system.
4. Storage and Shelf Life Issues
This product should be stored in a cool, dry, and well-ventilated warehouse, with a recommended storage temperature ≤40°C, avoiding freezing and high temperatures. Containers must be kept sealed and protected from moisture. Under proper storage conditions, the product's shelf life is typically one year. Products beyond the shelf life or stored under substandard conditions should be performance-verified or consult the technical team before use.
Method 1: Phone Consultation
Call the Technical Department of Hai'an Guoli Chemical Co., Ltd. directly to receive one-on-one guidance from a technical engineer. Before calling, please prepare the product batch number, process conditions, and a specific description of the problem so that the engineer can quickly locate the issue.
Method 2: Online Technical Ticket
Submit a technical ticket through the Guoli Chemical official website or WeChat official account, describing the problem encountered during product use. You can upload auxiliary information such as product appearance photos and application process parameters. The technical support team will respond as soon as possible on working days.
Method 3: Sample Delivery for Analysis
If the problem is complex, coordinate with the technical team to send the problematic sample to the Guoli Chemical Technology Center for analysis and testing, including but not limited to cloud point test, hydroxyl value determination, and emulsifying power evaluation, to determine whether the product performance is normal.
Method 4: On-Site Technical Guidance
For important customers or complex application scenarios, Guoli Chemical can arrange technical engineers to provide on-site debugging and guidance services, helping customers optimize formulation processes and usage plans.
To efficiently solve the problem, it is recommended to prepare the following information before contacting technical support:
When troubleshooting, always wear protective gloves and goggles to avoid direct contact with eyes and skin. In case of accidental contact, rinse immediately with plenty of water. For severe skin irritation, eye injury, or ingestion, refer to the first aid measures in the product safety data sheet and seek medical attention promptly.
