DESCRIPTION:
Blowing catalyst DMDEE is a high-boiling amine that can be used in flexible polyester foams, HR molded foams, and moisture-cured foams and coatings.
Blowing catalyst DMDEE is a good blowing catalyst that does not cause cross-linking.
When used in moisture-cured systems, Blowing catalyst DMDEE provides a stable prepolymer with a rapid cure.
Blowing catalyst DMDEE can also be used in flexible polyester-based urethane foams, as well as semiflexible foams and HR molded foams.
Blowing catalyst DMDEE 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, Blowing catalyst DMDEE plays a key role in the stability and polymerization of polyurethane prepolymer.
The product quality puts forward extremely high requirements.
Blowing catalyst DMDEE is an amine blowing catalyst particularly suitable for one- and two-component rigid foam sealant systems as well as flexible slabstock foams.
Blowing catalyst provides system tability in moisture cured polyurethane systems.

APPLICATION OF BLOWING CATALYST DMDEE:
Blowing catalyst DMDEE 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.
Blowing catalyst DMDEE accounts for 0.3-0.55% of the polyether/ester component.
Blowing catalyst DMDEE can be used in one- and two-component sealant foams as well as flexible slabstock foams.
Blowing catalyst DMDEE is an amine catalyst suitable for curing systems.
Blowing catalyst DMDEE is a strong blowing catalyst.

Security:
Blowing catalyst DMDEE 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:
Blowing catalyst DMDEE Should be sealed and stored in a dry, cool, ventilated warehouse, and sealed at room temperature.
Recommends that Blowing catalyst DMDEE be stored in a dry and cool area under appropriate ventilation conditions.
Each container should be closed tightly to avoid contamination with moisture or other negative influences that could change the products’ performance in the end use.
The optimum storage temperature is between 10 °C and 30 °C.
Lower and higher storage temperatures are not preferable and should be avoided.
