Polyurethane catalyst DMDEE

Overview:

Morpholine diethyl ether is used as a one-component polyurethane system (such as one-component polyurethane sealant, one-component polyurethane foam, one-component polyurethane The catalyst (or curing agent) in grouting materials, etc.). Since one-component polyurethane prepolymer requires long-term storage stability, bismorpholine diethyl ether plays a key role in the stability and polymerization of polyurethane prepolymer. The product quality puts forward extremely high requirements.

Physical and chemical performance:

Bismorpholinyl diethyl ether is colorless to pale 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℃;

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

Application:

2,2-bismorpholinyl diethyl ether is suitable for water curing systems, A strong blowing catalyst, due to the steric hindrance of amino groups, can extend the storage period of NCO components, suitable for the catalytic reaction of NCO and water in systems such as TDI, MDI, and IPDI; 2,2-Bismorpholinyl diethyl ether is mainly used in one-component rigid polyurethane foam systems, and can also be used in polyether and polyester polyurethane soft foams, semi-rigid foams, CASE materials, etc. It accounts for 0.3-0.55% of the polyether/ester component.

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

Security:

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

Storage and transportation:

Should be sealed and stored in a dry, cool, ventilated warehouse, and sealed at room temperature.

Packaging:

200KG/bucket Storage: It is recommended to store in a dry and cool area with proper ventilation. After the original packaging, please fasten the packaging cover as soon as possible to prevent the product performance from being mixed with other substances such as waterproof grade. Do not inhale dust and avoid contact with skin and mucous membranes. Smoking, eating and drinking are prohibited in the workplace. After work, take a shower and change clothes. Store contaminated clothes separately and use them after washing. Maintain good hygiene habits.
