Surfacol 420-440-465

Surfacol 420-440-465

Products Description

100% active, nonionic surfactants, silicone-free, APE-free, FDA compliant.

Non-foaming Dynamic Wetting Agent for reducing dynamic surface tension in waterborne systems including coatings, inks, adhesives, pigment dispersions, dispersed dyes, agricultural chemicals and ore floatation etc. also as molecular defoamer performance

Chemical Composition
100% Ethoxylated Acetylenic Diol, 

Modified based on SURFACOL 104 for better water solubility.

---SURFACOL 420
Ethoxylation Degree 1.3 moles
100% liquid lowest degree of ethoxylation, for best defoaming, HLB Value=4
Ethoxylation improves compatibility and allows higher dosage in water-based formulations resulting excellent dynamic wetting, especially suitable for high speed demanding applications such as aqueous wood coatings, auto coatings, industrial coatings, printing inks, overprint vanish, pressure sensitive adhesives and laminating adhesives, pigment dispersions, cement and agricultural chemicals etc. Surfacol-420 also used as a defoamer in some of these applications.

---SURFACOL 440
Ethoxylation Degree  3.5 moles
100% liquid low degree of ethoxylation, HLB Value=8
Medium ethoxylation improves compatibility and allows higher dosage in water-based formulations resulting excellent balance between dynamic wetting and foam control, especially suitable for high speed demanding applications such as aqueous wood coatings, auto coatings, industrial coatings, printing inks, overprint vanish, pressure sensitive adhesives and laminating adhesives, pigment dispersions, cement, agricultural chemicals and metal working fluid etc.

---SURFADOL 465
Ethoxylation Degree  10 moles
medium degree of ethoxylation watersoluble, HLB Value=13
Higher ethoxylation improves compatibility and solubility in water with low foaming tendency. Surfacol-465 shows higher electrolyte concentration tolerance and its higher cloud point allows applications under higher temperature, providing good dynamic wetting properties in functional coatings, inkjet inks, pressure-sensitive adhesives, fountain solutions, latex dipping, agricultural chemicals, metal working fluid and electroplating etc.
*** Higer degree of ethoxylation, better solubility in water, but weaker wetting and de-foaming performance.

 

Applications

SURFACOL 400 uses can be in following applications:

1. Printing ink
2. Flexo-and gravure inks
3. Metal working fluids
4. Fountain Solutions
5. Waterborne Internal Can Coatings
6. Pressure-Sensitive Adhesives
7. Emulsion polymerisation

General Dosage & Instruction
-General use levels at 0.1% – 3% based on total formulation.
-Adding surfactant at early stage of formulation for better dissolution.
-Moderate agitation for minimum 15-30 minutes for maximum mixing.
-Addition to the coating as supplied or as a pre-dilution is possible.
-Addition to the grind is recommended in pigmented systems.
-Applying ladder study for optimal dosage and conditions of addition.
