Product introduction

DABCO BL-11 (A-1) 70% dipropylene glycol solution of bis (dimethylaminoethyl) ether, strong foaming catalyst, commonly known as catalyst A-1 or A1 in domestic industry. A-1 catalyst is mainly used in the production of soft polyether polyurethane foam plastics, and also in hard foams for packaging. A-1 is especially effective in water, so it can reduce foam density. Its effectiveness in controlling the production of gas is about 80%, and the effect on controlling the gel reaction is about 20%. The catalyst has high activity and low dosage, and can control foaming and gelation time by adjusting the dosage of the series. The common use of A-1 and organotin catalyst can obviously improve the production tolerance of foamed plastics, ensure that no unnecessary quality problems are caused by careless operation or small errors in measurement system, and produce high-quality soft foamed plastics. A-1 catalyst is widely used in various formulations of polyurethane foams, especially in the production of high resilience, semi-rigid foams and low density foams.

Product specification

DABCO BL-11 (A-1) is a light yellow transparent liquid at room temperature, soluble in water; viscosity (25 C): 4.1mPa.s; density (25 C): 0.902g/cm3; flash point (PMCC): 74 C; vapor pressure (20 C): 1.3Pa; boiling range: 186-226 C.

Packing

It is packed in a clean, dry, sealed and leak-free special plastic drum with a net weight of 25kg.

storage and transportation

When transporting catalyst A-1, it should be strictly prevented from raining and contamination, and handled carefully to prevent leakage from collision with hard objects. When storing catalyst A-1, it should be stored at room temperature in a ventilated and dry warehouse to avoid damp environment, and the storage temperature should be kept below 25 C, avoiding sunshine exposure as far as possible, away from water sources and heat sources. In order to prevent moisture absorption and oxidation, it is suggested to fill the container with nitrogen.

Quality guarantee period

Under the correct storage conditions, the shelf life is 6 months from the date of production, and it can still be used after the expiration of the shelf life.

security information

Catalyst A-1 is toxic to some extent and should be washed with soapy water in time after contact with skin. Workers can wear eye shields or safety glasses to protect their eyes. Eye washing and washing equipment should be provided near the workplace. Personal hygiene should be paid attention to when working in places where products may be contacted. Washing products should be used to clean the skin contacted with products before diet, smoking and leaving work.

Leakage treatment

Prevent leakage as much as possible while ensuring safety. If minor leaks are found, they can be treated with sand or other absorbent materials and then placed in clean, dry containers for subsequent treatment. If a large number of leaks occur, the leaked materials should be collected for subsequent treatment. Material should be avoided from entering groundwater or surface water because it is not easily biodegradable. All leaked materials collected should be treated in accordance with the relevant regulations of the local environmental protection department.
