Reactivity
D-150 is highly miscible with standard organic solvents, such as alcohols, hydrocarbons and acetone.
D150 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 D-150 substantially.
Application and performance
D-150 may be used as water repellent to improve fillers dispersibility and reduces their sedimentation tendency.
D-150 may be used as an important component for sol-gel coating, and silicone resins.
For the manufacture of sealant materials RTV-2, D-150 can be used as a cross-linking agent.
