Lonzacure M-CDEA 4,4'-Methylenebis-(3-chloro, 2,6-diethyl)-aniline 106246-33-7 Lonza Crosslinking / Coupling / Curing Agents >> Amine Epoxy Resins Polyurethane Soluble in organic solvents Dispersible in polyols 4,4'-methylenebis-(3-chloro, 2,6-diethyl)-aniline. Lonzacure M-CDEA is an excellent chain extender for elastomeric polyurethanes (PU) and also a curing agent for epoxides (EP). It provides improved mechanical and dynamic properties which cannot be achieved with standard formulations. In addition it may be used as a precursor for polyimides and as an intermediate for organic syntheses. PU formulations based on Lonzacure M-CDEA are suitable for cast elastomers, RIM elastomers, coatings, adhesives, elastomeric foams and thermoplastic PU (TPU). In EP it is suitable for tooling, prepregs and chemical resistant coatings. excellent dynamics, excellent temperature resistance, low water absorption, hydrolytic stability, light stability excellent chemical stability against acidic and basic reagents, high Tg (up to 230°C), not toxic, approved for food contact in EU No hazardous Substance Excellent Mechanical Properties Excellent Dynamic Performance - Low Heat Build Up Superior Hydrolytic Resistance Temperature Resistance up to 130 °C Good Light/Colour Stability Benzenamine. Used as a chain extender for elastomeric polyurethanes and as a curing agent for epoxides in chemical resistant coatings. Provides very good dynamics, temperature resistance, low water absorption, and hydrolytic and light stability in polyurethanes. Offers very good chemical stability against acidic and basic reagents, high Tg (up to 230°C) and no toxicity in epoxides. Gives very good mechanical properties and low heat build up.
