Description

Dextrol™ OC-180 is a phosphate ester surfactant primarily used in waterborne architectural coatings. Here's a detailed overview of its properties, benefits, and recommended uses:

Description

Dextrol OC-180 is the neutralized (potassium salt) form of an ethoxylated aliphatic alcohol phosphate ester. It is formulated to enhance gloss and color acceptance in waterborne latex paints and can act as a supplemental dispersant to reduce pigment flocculation. This surfactant does not contain alkyl phenol ethoxylates (APEOs).

Typical Properties

Chemical Type: Phosphate Ester (anionic)
Appearance: Clear liquid
Active Solids: 45 ± 2%
Moles of EO (Ethoxylation): 6
Gardner Color: 6 maximum
Viscosity: 400-900 cps (measured using Brookfield LV at 25°C, spindle #3 at 30 rpm)
Density: 1.07 g/mL (8.9 lb/gal)
pH (10% aqueous solution): 6.0-7.0
Flash Point: > 200°F (93°C, Tag closed cup)

These properties are typical values and not product specifications.

Product Benefits

Performance:
- Increases gloss
- Enhances color properties
- Improves substrate wetting
- Excellent wetting and dispersion of pigments
Additional Benefits:
- Low water sensitivity
- Inhibition of flash and nail head rusting
- May improve freeze-thaw resistance
- May improve open time and block resistance

Recommended Use Levels

In Paints: For flat, semi-gloss, and gloss paints, the recommended usage is 5-10 pounds of Dextrol OC-180 per 100 gallons of finished paint, corresponding to 0.5-1.0%.
In Universal Colorants: Recommended at 5-10% by weight on pigment to help disperse and stabilize pigments, enhancing color acceptance in water-based paints tinted at point-of-sale.

VOC Content

Dextrol OC-180 is formulated to be solvent-free, with non-detectable VOC content when tested using the standard U.S. EPA Reference Method 24.

Summary

Dextrol OC-180 is a versatile and effective phosphate ester surfactant that enhances the performance and stability of waterborne architectural coatings. Its ability to improve gloss, color acceptance, and pigment dispersion, along with its low water sensitivity and potential to improve other paint properties, makes it a valuable additive for various water-based paint formulations and universal colorants.
