Product Description

P-84 is a high-performance, mid-molecular-weight non-ionic block copolymer surfactant. Characterized by an engineered intermediate HLB value of 9–12 and an elevated cloud point of ~74°C, this 100% active copolymer bridges the gap between lipophilic and hydrophilic phases with outstanding thermal stability. It serves as an elite co-emulsifier, wetting agent, and structural stabilizer, ensuring exceptional formulation integrity and long shelf life in challenging, high-shear multi-phase industrial systems.

Key Applications & Technical Benefits

• Multi-Phase Emulsification: Functions as an exceptional co-emulsifier and coupling agent for oil-in-water (O/W) and water-in-oil (W/O) systems, widely utilized in advanced personal care, agricultural, and industrial cleaning matrices.

• Metalworking Fluids & Lubricity Modifier: Highly recommended as a crucial stabilizing agent and lubricity improver in semi-synthetic and full-synthetic metalworking fluids (MWFs), protecting emulsions from thermal splitting under severe high-speed tool cutting shear.

• Advanced Pigment & Additive Dispersion: Delivers elite performance in wetting and dispersing fine pigment particles, fillers, and mineral additives in water-borne coatings, effectively preventing hard settling and flocculation.

• High Thermal Stability: The high cloud point (~74°C) guarantees that the formulated emulsion retains its phase homogeneity and viscosity profile even in warm, highly demanding mechanical operating environments.
