Applications and Performance：

QP-553 is highly miscible with standard organic solvents,such as alcohols, hydrocarbons and acetone.

QP-553 is practically insoluble in neutral water and reacts only slowly to form silanols and higher condensation products. Addition of a hydrolytic catalyst (inorganic/organic acids, ammonia or amines) accelerates the hydrolysis of QP-553 substantially. (Filler Modifier) QP-553 is used mainly to render a wide range of surfaces and materials water repellent (e.g.mineral fillers,pigment,glass cardboard). QP-553 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.

QP-553 is also used in the production of silicone resins and condensation-curing silicone rubber
