14579-90-9 - Introduction

1,3-di-n-propyl-1, 1,3,3-tetramethyldisilazane is an organosilicon compound often abbreviated as DBDPS. The following is an introduction to the nature, use, formulation and safety information of DBDPS:

Nature:
1,3-di-n-propyl-1, 1,3,3-tetramethyldisilazane is a colorless to light yellow liquid with a special silicone structure. It has low volatility and high thermal stability.

Use:
DBDPS is mainly used as a flame suppressant and heat stabilizer. It can be added to plastics, coatings, polymers, rubber and other products to improve its flame retardant properties and thermal stability. In addition, DBDPS is also widely used in electronic products, cables, auto parts and other fields.

Method:
Generally speaking, DBDPS can be synthesized by N'-N,N,N-tetramethyl -1,3-Di/1,1,3,3-tetramethyldisilazane and N-propanol reaction. The reaction is generally carried out under an inert atmosphere and in the presence of a corresponding catalyst.

Safety Information:
Under normal use and storage conditions, DBDPS is relatively safe. However, as an organosilicon compound, care should be taken to avoid skin contact and inhalation. Appropriate personal protective equipment, such as chemical protective gloves, goggles and face shields, should be worn. When using DBDPS, please refer to the safety data sheet and operating guide provided by the vendor. In case of accidental contact or inhalation, seek medical attention immediately.
