Thank God I found Homestead on time. I was able to give my elder family member a loving home which I could not give. Thanks to the Homestead community to help him go.

Amazing service and even more impressive behaviour. I liked their management system and how they treat the elders. . Ut enim ad minim

Substrate wetting Additive——AEOR 104 pigment and substrate wetting

2,4,7,9-Tetramethyl-5-decyne-4,7-diol; SURFYNOL® 104; CAS 126-86-3; Substrate wetting Additive; Nonionic Low-foam Super Dynamic Wetting Agent

AEOR 104 is a multi-functional surfactant that combines dynamic wetting and molecular defoaming in waterborne coatings, inks, paints, adhesives, pigment manufacture and dispersion, cements, metalworking lubricants, agricultural chemicals, and dye processing.AEOR 104 is available in liquid form in different solvent cuts. AEOR 104 Substrate wetting Additive 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 AEOR 104 Substrate wetting Additive typically results in significantly reduced water sensitivity compared to either conventional ethoxylated or anionic surfactants.

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
  •  
KEY BENEFITS
  • pigment and substrate wetting
  • very good foam control
  • reduced water sensitivity
