主要特点与优势

Eliminates surface defects: Completely silicone-free, preventing craters, pinholes, and fish-eyes in sensitive coating applications.
Enhanced recoatability: Ensures excellent inter-coat adhesion, crucial for multi-layered paint systems and automotive finishing.
Broad pH stability: Maintains peak performance across acidic and alkaline environments, ranging from pH 3 to 12.
Thermal resilience: Stable under high-temperature processing without phase separation or loss of efficacy.
Environmental safety: Formulated with biodegradable components, meeting strict VOC regulations and environmental safety standards.
Low dosage efficiency: Provides potent foam control at concentrations as low as 0.1%, reducing total formulation costs.
Highly compatible: Mixes easily with various resins and binders without turbidity.

规格

技术亮点

Chemical Composition: Proprietary blend of modified fatty alcohols and polyoxyalkylene glycol esters (Non-silicone).
Physical Appearance: Off-white to amber translucent liquid; easily dispersible in water.
Specific Gravity: 0.85 – 0.95 at 25°C, ensuring optimal buoyancy and surface activity.
Active Content: High concentration (typically 95-100% active), minimizing the addition of inert carriers.
Surface Tension: Significantly lower than standard surfactants, facilitating rapid penetration of the lamellae.
Ionic Character: Non-ionic, providing exceptional compatibility with anionic, cationic, and amphoteric surfactant systems.
Flash Point: >150°C (Closed Cup), ensuring safety during high-heat industrial manufacturing processes.
Viscosity: Low-to-medium viscosity (200-500 cPs) allows for easy pumping and accurate metering.

实际行业应用

应用领域

Paints and Coatings: Essential for waterborne architectural coatings, wood finishes, and industrial primers requiring perfect surface aesthetics.
Adhesives and Sealants: Controls air entrainment during high-speed mixing of emulsion polymers, pressure-sensitive adhesives, and laminating glues.
Textile Processing: Used in dyeing, scouring, and finishing baths where silicone spots on fabrics must be avoided.
Water Treatment: Effective in municipal and industrial wastewater plants, particularly in aeration tanks and biological treatment units.
Paper and Pulp: Manages foam in pulping, bleaching, and paper-making processes, preventing sheet defects and improving drainage efficiency.
Metalworking Fluids: Stabilizes lubricants and coolants by preventing foam build-up in recirculating machining systems.
