Description

Diammonium 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,12,12,13,13,14,14,15,15,16,16,17,18,18,18-Dotriacontafluoro-17-(Trifluoromethyl)Octadecyl Phosphate is a highly fluorinated phosphate ester salt, engineered to deliver exceptional surface activity and chemical resistance. This compound is critical for applications demanding extreme hydrophobicity, oleophobicity, and stability in harsh chemical environments. It is primarily utilized by formulators in the specialty coatings, fire-fighting foams, and advanced material sectors where durable, low-surface-energy properties are paramount.

Application

• Fluorinated Surfactant & Leveling Agent: A key ingredient in high-performance fluorosurfactants for coatings, inks, and paints to improve wetting, leveling, and reduce surface defects.
• Aqueous Film-Forming Foam (AFFF) Concentrates: Used in the formulation of fire-fighting foams for flammable liquid fires, contributing to rapid film formation and fuel vapor suppression.
• Stain & Soil Repellent Treatments: Imparts durable water, oil, and stain resistance to textiles, carpets, leather, and paper products.
• Specialty Polymer Additive: Functions as a processing aid or anti-static agent in fluoropolymers and high-performance engineering plastics.
• Metalworking Fluids & Lubricant Additive: Enhances lubricity and provides anti-corrosion properties in demanding industrial fluid formulations.
• Electronic Chemicals: Potential use as a surfactant in photoresist developers and etching solutions for semiconductor manufacturing.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which may affect product quality.
