Product Details

M-CDEA

 

 

Product introduction:

Chemical name: 4,4'-methylenebis(3-chloro-2,6-diethylaniline)

Molecular formula: C21H30Cl2N2

Relative molecular mass: 379.38

CAS number: 106246-33-7


 

Physical properties:

Gray-white crystalline powder or granules, melting point 87-90 ° C, apparent density: 0.61-0.65 g/cm 3 , stability greater than 3 years. When reacted with isocyanate, the equivalent weight is 187.8-191.6. M-CDEA is soluble in toluene, xylene, DMF, DMSO, aniline, insoluble in water, completely soluble in 80 ° C triethylene glycol, 50% M-CDEA triethylene glycol solution from 80 o C was cooled to 40 ° C for 48 hours without crystallization, which was recrystallized from methanol.

Purity: 97.0% Min.

Moisture: 0.15% Max.

Among them LONZACURE M-CDEA GS is a granular product, LONZACURE M-CDEA PQ is a light color product.

 


Performance and use:

M-CDEA is a low-toxic, high-performance curing agent or chain extender approved by the European Union for food contact applications. The obtained product has good dynamic mechanical properties, temperature resistance, hydrolytic stability, light stability and low water absorption. M-CDEA can be applied to cast polyurethane elastomer, RIM elastomer, coating, adhesive, microporous Elastomers and thermoplastic polyurethanes. It can also be used in polyimides and as intermediates in organic synthesis. Used in epoxy resin curing agents, the product has excellent chemical resistance, acid and alkali resistance, high glass transition temperature Tg (up to 230 ° C).
