Dynamic Wetting Agents SURFADOL ® 541L Pure Solid CAS 126-86-3
SURFADOL ® 541L
Nonionic Dynamic Wetting Agent and Molecular Defoamer
SURFADOL® 541L Surfactant
Surfadol 541L surfactant has a unique Gemini structure, which brings a unique combination of performance benefits, such as surface tension reduction, foam control, and viscosity stabilization. The hydrophobic nature of Surfadol 541L surfactant typically results in significantly reduced water sensitivity compared to either conventional ethoxylated or anionic surfactants.
Due to its multifunctional properties, Surfadol 541L surfactant can be used in many water-based applications such as coatings, paints, adhesives, inks, pigment manufacture and dispersion, cements, metalworking lubricants, agricultural chemicals, and dye processing.
Easy-to-handle liquid preparations of Surfadol 541L are also available.
Special properties
- Quick migration, leading to low dynamic surface tension
- Ability to wet contaminated substrates
- Non-micelle forming
- Thermal and chemical stability over a broad range of conditions
- Prevents surface defect problems such as fisheyes, crawling, and cratering on low-energy substrates
- Reduces microfoam in spray-applied systems
- Improves pigment grind efficiency
- Reduces water sensitivity
- Defoams, deairentrains, and improves flow
- Enhances leaf and soil penetration while improving bloom and stability in agricultural chemicals
- Lubricates, wets, and prevents smut formation while eliminating hot spots in metalworking fluids
- Silicone-free, APEO free, non-toxic
Examples of application
- Water-based printing inks
- Water-based adhesives
- Dye processing
- Fountain solutions
- Waterborne coatings
- Metalworking fluids
- Overprint vanishes
- Agricultural chemicals
- Concrete and drymix mortars
Processing instructions
- Mix well when use.
- Added and mixed after other surfactants.
- Pigments, fillers or other solid should be added after Surfadol 541L surfactant has been evenly mixed.
