II. Product Characteristics

(1) Physical and Chemical Properties

• Appearance: Colorless to light yellow transparent liquid with a mild odor, easily soluble in water and most polar solvents.
• Molecular Weight: 103.17 g/mol. Its low - molecular - weight structure enables fast diffusion speed in the system.
• Alkalinity: Strongly alkaline. The pH value of a 10% aqueous solution at 25°C is approximately 11.5, which can effectively adjust the acidity and alkalinity of the system.
• Boiling Point: Approximately 165°C. It has lower volatility than ammonia water and can reduce VOC (Volatile Organic Compounds) emissions.
• Compatibility: It has excellent compatibility with systems such as coating emulsions, metalworking fluids, and adhesives, without causing precipitation or stratification.

(2) Core Functional Advantages

• Multi - Functional Synergistic Effect:
  • Dispersion and Anti - Agglomeration: When used in coatings to replace ammonia water, it can not only disperse pigment particles but also prevent pigment re - agglomeration through charge repulsion, improving the uniformity of the coating film.
  • pH Adjustment: It stabilizes the acidity and alkalinity of the system, ensuring the stability of latex particles, especially suitable for water - based coatings and inks sensitive to pH.
  • Thickening Effect: It works synergistically with thickeners such as cellulose ethers to increase the system viscosity and improve workability (e.g., anti - sagging property).
  • Anti - Microbial Property: It inhibits the growth of bacteria and molds in the system, extends the product shelf life, and reduces the amount of preservatives used.
• Environmental and Cost Advantages:
  • It has low VOC characteristics, complies with environmental regulations (such as EU REACH and US EPA standards), and is suitable for green coatings and adhesives.
  • A small amount (usually 0.1% - 0.5%) can achieve multiple effects, reducing the total cost of the formula.
• Performance Stability:
  • It has good temperature resistance and stable performance below 100°C without decomposition or discoloration.
  • It has strong chemical inertness and does not undergo side reactions with pigments, fillers, and additives in the system, ensuring long - lasting product performance.

III. Action Principle

1. Dispersion and Anti - Agglomeration Mechanism: The amino group (-NH₂) in the AMP - 95 molecule is adsorbed on the surface of pigment particles to form a charge layer (positively charged). It prevents particle agglomeration through electrostatic repulsion. At the same time, the hydroxyl group (-OH) forms hydrogen bonds with water molecules, enhancing the wettability of particles in water.
2. pH Adjustment and Thickening Principle: The amino group reacts with free acids in the system to neutralize acidic substances and increase the pH value. When the pH value rises, the molecular chains of thickeners (such as associative polyurethanes) in the coating stretch, increasing the viscosity.
3. Anti - Microbial Effect: The alkaline environment inhibits the activity of microbial enzymes. At the same time, the amino group penetrates the microbial cell membrane, destroys its physiological functions, and achieves a bactericidal effect.

IV. Applicable Scenarios

(1) Coating and Ink Industry

• Water - Based Coatings: As a main additive, it adjusts the pH value of latex paint, improves pigment dispersion, reduces floating color and blooming, and enhances the gloss and scrub resistance of the paint film.
• Printing Inks: It stabilizes the ink viscosity, prevents pigment sedimentation, and ensures uniform printing colors, especially suitable for gravure printing and flexographic printing.

(2) Metal Processing Field

• Cutting Fluids and Grinding Fluids: It adjusts the pH value to the alkaline range (8.5 - 9.5), inhibits bacterial growth, and at the same time enhances the effect of rust inhibitors, extending the service life of processing fluids.
• Metal Cleaners: As an auxiliary detergent, it improves the oil emulsification ability and works with surfactants to enhance cleaning efficiency.

(3) Adhesive and Sealant Industry

• Water - Based Adhesives: It adjusts the pH value of the system, stabilizes the emulsion polymerization process, and improves the adhesion of the adhesive to substrates (such as wood, metal, and plastic).
• Sealants: It controls the curing speed, improves construction convenience, and at the same time reduces VOC emissions during the curing process.

(4) Personal Care and Sewage Treatment

• Shampoos/Bath Gels: It adjusts the pH value to a weakly acidic range (5.5 - 6.5) to match the skin's acidity and alkalinity and enhance formula stability.
• Sewage Treatment: It acts as a pH adjuster to neutralize acidic wastewater. At the same time, its amino group can complex with heavy metal ions to assist in sewage purification.

V. Usage Methods and Precautions

(1) Usage Methods

• Addition Amount:
  • Coatings/Inks: 0.1% - 0.5% (based on the total formula amount). It is recommended to determine the optimal dosage through viscosity - pH curve testing.
  • Metalworking Fluids: 0.2% - 1.0%, adjusted according to water hardness and service cycle.
• Addition Method:
  • In coating production, it can be added during the grinding stage (when pigments are dispersed) or the paint mixing stage, and then stirred evenly.
  • In metalworking fluids, it can be directly added to the concentrate or working fluid. It is recommended to dilute it 10 - 20 times before adding to avoid local over - alkalinity.

(2) Precautions

• Storage Conditions: Store in a sealed container in a cool and dry place, avoid direct sunlight. The storage temperature is recommended to be 5 - 35°C, and keep away from strong acids and strong oxidants.
• Safety Protection: Wear rubber gloves and goggles during operation. If it comes into contact with the skin, rinse with clean water for 15 minutes. If accidentally ingested, drink milk immediately and seek medical attention.
• Compatibility Taboos: Avoid direct mixing with acidic substances (such as citric acid and acetic acid). Before use, it is necessary to test the compatibility of the system (such as appearance, viscosity, and pH stability).
