Core Application Areas
1. Industrial Water Treatment: Circulating cooling water, biochemical wastewater, defoaming in reverse osmosis systems; preventing stubborn foam generated during aeration.
2. Water-based Industrial Coatings: Defoaming in latex paints and water-based industrial coatings during grinding and mixing processes to avoid defects like pinholes and shrinkage.
3. Papermaking Industry: Defoaming in papermaking white water and pulping processes to improve pulp filtration efficiency.
4. Industrial Cleaning: Defoaming in strong alkaline water-based cleaners, metal degreasing agents, and spray cleaning solutions.

Related Applications: Suitable for use in pharmaceutical fermentation, food processing (food-grade customized products), pesticide formulations, dyeing and printing industries.

Storage, Transportation & Packaging Information
1. Packaging: 25kg/50kg HDPE plastic drums, sealed for storage.
2. Storage Conditions: Store in a cool warehouse at 5–30°C. Keep away from strong oxidizers, direct sunlight, and high temperatures. Normal shelf life is 12 months.
3. Transportation: Suitable for regular chemical goods. No UN number required. Can be transported by standard truck or courier services. Not subject to hazardous materials transportation regulations.

Safety Instructions 
1. Protection against contact: Wear nitrile gloves and protective goggles during handling. Ensure proper ventilation in the workshop.
2. Emergency procedures: In case of skin contact, wash with soapy water. If it gets into the eyes, rinse thoroughly with water for 15 minutes. If swallowed in large quantities, seek medical attention immediately and drink plenty of warm water.
3. Waste disposal: Dispose of waste according to standard industrial solid waste regulations. Do not discharge it directly into water bodies without proper treatment.

I. Water Treatment Industry (Primary Applications)
1. Municipal/Industrial Biochemical Wastewater Treatment: Foam suppression in aeration tanks and aerobic fermentation tanks; ensures biochemical bacteria survive without damaging sludge activity.
2. Circulating Cooling Water Systems: Central air conditioning and power plant cooling water systems – prevents foaming of chemicals and overflow in sumps.
3. Reverse Osmosis/Pure Water Production: Foam removal before RO treatment to prevent damage to membrane elements.

II. Coating Industry
1. Water-based Industrial Paints, Latex Paints, Acrylic Emulsions: Foam elimination during grinding, mixing, and filling processes to prevent pinholes and shrinkage in the paint film.
2. Water-based Adhesives, Inks: Foam control during production mixing and coating to maintain paint adhesion and gloss.

III. Papermaking Industry
1. Pulp Making: Foam removal from pulp washing and black liquor at medium-low temperatures.
2. Papermaking White Water, Papermaking Processes: Foam management in white water systems to improve filtration speed and reduce paper defects.

IV. Industrial Cleaning
1. Water-based Degreasing Agents, Metal Spraying Cleaners: Foam suppression in aluminum/steel degreasing processes and strong alkaline cleaning solutions.
2. Household Cleaning Solutions, Pipe Cleaners: High-surface-active-agent systems for foam control.

V. Fine Chemicals (Corresponding to Previous Categories)
1. Pharmaceuticals (Active Ingredients/Intermediates): Antibiotic and amino acid fermentation process foam suppression using pharmaceutical-grade GPE materials with LD50 > 5000 mg/kg.
2. Food Additives: Used in sugar production, yeast fermentation, and soy product processing (food-grade, GB2760 standards).
3. Agricultural Chemicals: Foam removal during pesticide solution, suspension, and fertilizer liquid production.
4. Dyes & Pigments: Foam suppression in water-based dye grinding and pre-treatment processes.
5. Surfactant/Adhesive Synthesis: Foam control in reactors used for producing non-ionic and anionic surfactants.

VI. Other Applications
1. Biodegradation: Foam suppression during fermentation of various microorganisms and enzyme production.
2. Building Materials: Foam removal from water-based putties and concrete admixtures.
