BELSIL® ES 3007 is used to render a wide range of materials water repellent (e.g. fillers, coating of pigments etc.). BELSIL® ES 3007 is also used in the production of silane-crosslinking formulations.
Processing
General processing information:
BELSIL® ES 3007 is highly miscible with standard solvents such as alcohols and acetone.
BELSIL® ES 3007 is practically insoluble in neutral water and reacts only slowly to form silanols. Addition of a hydrolytic catalyst (inorganic/organic acids, ammonia or amines) accelerates the hydrolysis of BELSIL® ES 3007.
Using standard coating techniques, undiluted BELSIL® ES 3007 can aid in the dispersion of inorganic pigments and fillers in coatings and sealants. This can lead to lower viscosity in the formulated product and can improve the hiding power of a coating.
BELSIL® ES 3007 as a filler modifier: BELSIL® ES 3007 may be used pure or in solution to treat fillers, using suitable mixing equipment. It may be necessary to first pre-treat the substrate with water and/or a catalyst.
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.
