L62
Jienuo
Propylene glycol block polyether L62 (CAS 9003-11-6), also called PPG block polyether L62 or PEO-PPO block copolymer, is a non-ionic polyether surfactant. As a versatile industrial additive, it functions as an emulsifier, dispersant, and wetting agent, with low foam properties. Widely applied in pesticides, coatings, detergents, and chemical formulations, it enhances product stability, improves mixing efficiency, and suits both industrial and agricultural scenarios. Its water-soluble, customizable viscosity features make it a flexible choice for various manufacturing processes.
Product Advantage
Low-Foam & Stable Performance
With a controlled HLB value of 7 and ≤1.0% moisture content, L62 maintains low foam during application—critical for processes like metal cutting or coating mixing, where excess foam disrupts efficiency. Its stable pH (5.0-7.0) ensures compatibility with most formulations without causing corrosion or degradation.
Multi-Functional Surfactant
Acts as an emulsifier, dispersant, and lubricant in one: it improves active ingredient dispersion in pesticides (reducing settling by 30% in trials) and enhances pigment uniformity in coatings, cutting mixing time by 20% for manufacturers.
Broad Compatibility
As a non-ionic polyether, it blends seamlessly with ionic/non-ionic additives in detergents, textile dyes, and chemical formulations. Its water-soluble nature also supports easy integration into aqueous systems without additional solubilizers.
Cost-Effective Industrial Grade
Supplied in 200kg/50kg packaging (2-year shelf life), L62 offers long-term stability for bulk storage. Its customizable application (e.g., metalworking lubrication) reduces the need for multiple additives, lowering overall production costs.

Product Uses
Metalworking
Serves as a cooling lubricant in metal cutting/grinding: it reduces friction between tools and workpieces, extending tool life by 15% while preventing workpiece corrosion. Mix 2-5% L62 with water for optimal performance.
Pesticide Formulations
Acts as an emulsifier for pesticide active ingredients: it ensures uniform dispersion in water-based sprays, improving coverage on crops and boosting pesticide efficacy by 20%.
Coatings & Inks
Functions as a dispersant for pigments: it prevents pigment settling in coatings/inks, enhancing color consistency and reducing streaking in finished products.
For aqueous systems (e.g., detergents, pesticides), add L62 directly to water (stirring at 50-60℃ for 5-10 minutes) until fully dissolved.
For metalworking lubricants, mix 2-5% L62 with base oil or water (adjust concentration based on machining intensity).
Store unused L62 in a dry, ventilated area (≤30℃) to maintain stability; avoid contact with strong acids/bases.
FAQ
What is L62's shelf life?
It has a 2-year shelf life when stored in sealed packaging in a dry, cool area (≤30℃).
Is L62 compatible with acidic formulations?
Yes—its pH (5.0-7.0) allows compatibility with mild acidic systems (pH ≥4.0); avoid strong acids (pH <3.0).
Can L62 be used in food-related applications?
No—L62 is industrial-grade and not formulated for food, pharmaceutical, or cosmetic use.
