Duomeen® TDO is an oil-soluble diamine surfactant that binds well to metal and mineral surfaces to provide a hydrophobic barrier coating.
Duomeen® TDO is a cationic alkyl diamine with a non polar fatty tail. It can be used as a filming amine or as wetting aid. Duomeen® TDO works well to adsorb onto metal surfaces and form a corrosion inhibiting barrier. it is frequently used for metal coatings that are subjected to marine climates. The same hydrophobic tails that prevent corrosion on metal also prove useful in waterproofing sealants. Duomeen® TDO can be used to improve the water resistance of construction and marine sealants. Duomeen® TDO is also an effective dispersing aid for hydrophobic pigments used in coatings, paints, and inks. Pigments that are dispersed with Duomeen® TDO have excellent color strength and rub resistance. In mining applications, Duomeen® TDO works well as a flotation collector for feldspar. Duomeen® TDO binds to the surface of feldspar making it hydrophobic making it easier to remove via froth flotation.
