DMDEE

Overview:

Morpholine diethyl ether is used as a catalyst (or curing agent) in single-component polyurethane systems (such as polyurethane single-component caulking agent, polyurethane single-component foam rubber, polyurethane single-component grouting material, etc.). Since the one-component polyurethane prepolymer requires long-term storage stability, bismorpholine diethyl ether plays a key role in the stability and polymerization of the polyurethane prepolymer, which is also important for the bismorpholine diethyl ether Product quality puts forward extremely high requirements.

Physical and chemical properties:

The appearance of bismorpholinyl diethyl ether is colorless to light yellow liquid, soluble in water.

Typical physical properties are:

Viscosity (25℃): 18mPa·s;

Relative density (25℃): 1.06;

Boiling point: greater than 225℃;

Melting point: less than -28℃;

Flash point (TCC): 146℃;

Amine value: 7.9 to 8.1 mmol/g.

The purity of industrial products is generally ≥99% or ≥98%, and the water content ≤0.5%.

 

application:

2,2-bismorpholinyl diethyl ether is suitable for water curing system and is a strong foaming catalyst. Due to the steric effect of the amino group, it can extend the storage period of the NCO component, suitable for TDI, MDI, IPDI, etc. Catalytic reaction of NCO and water in the system; 2,2-bismorpholinyl diethyl ether is mainly used for single-component rigid polyurethane foam system, and can also be used for polyether and polyester polyurethane flexible foam, semi-rigid foam, CASE materials, etc., add 0.3-0.55% of the polyether/ester component.

Bismorpholinyl diethyl ether is an amine catalyst suitable for curing systems. It is a strong foaming catalyst. Due to the steric hindrance of the amino group, the NCO-containing component can have a long storage period. It is mainly used for single-component rigid polyurethane foam system, and can also be used for polyether type and polyester type polyurethane soft foam, semi-rigid foam, CASE material, etc.

 

Safety:

Dimorpholinyl diethyl ether can burn eyes and skin. In case of contact with eyes, wash eyes immediately with plenty of water and seek medical treatment immediately. In case of contact with skin, rinse affected area immediately with water. During the material handling, it is advisable to wear splash-proof goggles, and it is advisable to wear butyl rubber gloves, rubber lab coats and rubber boots.
