Product Advantage
High Stability & Consistent Performance
It maintains stable properties across pH 5.0–7.0 and typical industrial temperatures, with ≤1.0% moisture content ensuring low impurity risk. Its fixed HLB value (13) guarantees reliable emulsification/dispersion effects in various formulations.
Low-Foaming & Multi-Functional
As a low-foaming surfactant, it suits scenarios requiring minimal foam (e.g., metalworking fluids). It also acts as an emulsifier, dispersant, and stabilizer, reducing the need for multiple additives.
Wide Compatibility
Compatible with most substrates and industrial materials, it integrates seamlessly into pesticides, coatings, and detergents. Food-grade options meet global compliance standards for diverse applications.
Controlled Viscosity & Easy Handling
Available as a liquid/paste with manageable viscosity, it simplifies blending in production processes—no special equipment required for formulation.

Product Uses
Pesticide Formulations
Serves as a stable emulsifier for pesticide preparations, ensuring uniform mixing with active ingredients. The formulated products remain stable during storage without stratification.
Metalworking Fluids
Acts as a low-foaming lubricant and stabilizer in metal cutting/grinding fluids, reducing foam buildup while enhancing fluid longevity.
Coatings & Inks
Functions as a dispersant to improve pigment uniformity in coatings/inks, boosting product consistency and application smoothness.
Detergents
Used in low-foam, low-alkali synthetic detergents to enhance cleaning efficiency while minimizing residue.
Add L64 directly to the formulation system (e.g., pesticides, coatings) during mixing. The recommended dosage is 1–5% (adjust based on specific product requirements). Stir thoroughly at room temperature until fully dispersed—avoid high-temperature heating (exceeding 80°C) to preserve performance.
FAQ
What is L64's shelf life?
It has a 2-year shelf life when stored in a dry, ventilated area (avoid direct sunlight and moisture) in sealed iron/plastic drums.
Is L64 food-grade available?
Yes, food-grade L64 is offered, complying with relevant global food-contact material standards for appropriate applications.
Can L64 be used in acidic systems?
It performs stably in pH 5.0–7.0 systems; avoid use in strongly acidic (pH <4) environments to prevent performance degradation.
