BELSIL ES 3007 is a clear, colorless liquid with a characteristic odor which can be used as surface modifier to generate hydrophobicity on inorganic fillers and pigments, e.g. titandioxide. BELSIL ES 3007 is widely used in surface treatment for pigments in cosmetic vehicles and composites. It provides compatibility improvements between pigments or inorganic fillers and organic polymers or solvents, allowing easy pigment (e.g. iron oxides or titanium dioxide) or mineral filler (e.g. ATH, MDH) dispersion. BELSIL ES 3007 can couple inorganic pigments and fillers to organic resins. Coupling typically improves the moisture and chemical resistance of the coating or adhesive. Good wetting agent for colorants or pigments.
