Performance and Applications
OT-75 Surfactant offers superior wetting and permeation properties, greatly lowering surface tension and quickly saturating hard-to-wet substrates. It is commonly applied as a wetting and deposition aid in pesticide products.
- In coatings and inks, OT-75 Surfactant acts as an effective dispersing and emulsifying agent. It helps decrease viscosity, enhances pigment stability, reduces settling and flooding, and improves leveling and application characteristics, contributing to smooth and uniform film formation.
- In textile dyeing and printing, OT-75 Surfactant serves as a penetrating and leveling agent. It assists dye diffusion into fibers, increasing dyeing consistency and color fastness. It is also used in pretreatment to boost the penetration of scouring and bleaching agents, raising process efficiency.
Advantages
- Outstanding wetting and penetration capacity, quickly reducing surface tension to effectively treat difficult-to-wet materials.
- High formulation flexibility, compatible with anionic, non-ionic surfactants, and other additives, suitable for diverse systems.
- Strong environmental profile, characterized by good biodegradability and low toxicity, aligning with strict ecological standards in modern industry.
