Polyether defoamer GP-330 is a non-ionic defoamer with low toxicity and strong physiological inertia. Under normal use, its hazard is low, but individual protection, storage conditions, and emergency handling specifications must be observed to ensure operational safety and stable product performance.
First, a friendly correction: the term "small deformity" you mentioned should be a typo for "defoamer." The correct product name is Polyether defoamer GP-330 (also known as C12-14 alcohol polyoxyethylene polyoxypropylene ether, CAS number: 68439-50-9). The following are the key precautions for using this product.
Detailed Description
Polyether defoamer GP-330 is a high-efficiency defoaming and anti-foaming additive specially designed by Guoli Chemical for water-based systems. It appears as a colorless to slightly yellow transparent liquid. Its chemical properties are stable, with strong physiological inertia and no known significant hazard classification. However, basic chemical handling procedures should still be followed during operation. Under normal conditions, the product is non-flammable and non-explosive, but under extreme high temperatures, thermal decomposition may produce irritating fumes such as carbon monoxide and carbon dioxide. Therefore, ventilation should be enhanced in high-temperature processes.
In terms of usage, GP-330 has good water dispersibility and system compatibility, and its liquid form facilitates metering and addition. However, it should be avoided to store it with strong oxidizers and acids to prevent affecting product stability. The product has low toxicity to aquatic organisms, but it is strictly prohibited to discharge it directly into water bodies or soil without treatment. Waste should be disposed of by qualified professional agencies in accordance with regulations.
Complete Overview of Precautions
I. Personal Protective Requirements
- Eye protection: Wear sealed chemical safety goggles to avoid splashing into eyes.
- Hand protection: Wear chemical protective gloves (recommended material: nitrile rubber or neoprene).
- Body protection: Wear standard protective work clothes to avoid prolonged or large-area skin contact.
- Respiratory protection: No special protection is usually required for routine operations; however, when fumes are generated during high-temperature processing, wear an organic vapor/particulate filtering respirator.
- After operation: Thoroughly wash hands and any exposed skin.
II. Storage Requirements
- Store in a sealed container in a cool, dry, well-ventilated dedicated warehouse, away from fire and heat sources.
- Recommended storage temperature: 5°C to 35°C, avoid freezing and prolonged high-temperature storage.
- Use promptly after opening; reseal any unused product.
- Avoid storage with strong oxidizers and acids.
- The storage area floor should be impermeably treated and equipped with a dike to contain possible spills.
III. Emergency Handling Points
| Contact Type | Treatment Measures |
|---|
| Skin contact | Remove contaminated clothing, first wipe off with a dry cloth or paper towel, then rinse thoroughly with plenty of soapy water and clean water. If irritation persists, seek medical attention. |
| Eye contact | Immediately flush with plenty of running water, keeping eyelids open, for at least 15 minutes. Seek medical attention as soon as possible. |
| Inhalation discomfort | Move immediately to fresh air and keep breathing unobstructed. If symptoms persist, seek medical attention. |
| Ingestion | Do not induce vomiting. Rinse mouth with water and seek medical attention immediately. |
| Spill handling | Contain and collect with inert absorbent materials (e.g., sand, vermiculite), place in a sealed container for disposal as per regulations. Rinse residual liquid on the floor with clean water, but avoid allowing rinse water to enter drains. |
| Fire | The product itself is not easily flammable, but thermal decomposition may produce irritating fumes. Firefighters must wear self-contained breathing apparatus. Use water spray, foam, dry powder, or carbon dioxide for firefighting. |
IV. Application Operation Recommendations
- Addition method: The liquid form can be directly metered and added. It is recommended to add slowly under stirring to ensure uniform dispersion and avoid stratification or sedimentation.
- Dosage reference: Due to significant differences in application systems, it is recommended to determine the optimal dosage through small-scale tests. Typically, 0.01% to 0.5% of the total formulation can achieve good defoaming and anti-foaming effects (data source: Guoli Chemical application experience).
- System compatibility: Compatible with various water-based resins, additives, and formulation systems, not prone to causing coating defects such as craters or fish eyes.
- High-temperature conditions: The product has excellent temperature resistance and maintains stable defoaming activity under high-temperature conditions without easy decomposition or failure.
- Acid-base environment: Tolerates conventional acid-base environments and hard water conditions, reliably functioning in complex systems.
Precautions
- Emergency eyewash stations and safety shower facilities should be installed near the operation area.
- Prevent product overflow or splashing, and ensure it does not enter drainage systems, surface water bodies, or soil.
- The freezing point of this product is below -20°C, so it is not prone to freezing during low-temperature storage, but extreme low-temperature environments should still be avoided.
- Flash point >200°C (open cup method); no fire risk at room temperature operation, but still keep away from open flames.
- Specific packaging specifications: 200 kg iron drum, 50 kg plastic drum; custom packaging available upon customer request.
