Lonzacure M-DIPA 4,4'-Methylenebis-(2,6-diisopropyl)-aniline 19900-69-7 Lonza Crosslinking / Coupling / Curing Agents >> Amine Epoxy Resins Polyurethane Architectural / Decorative Soluble in chlorobenzene Insoluble in water @ 20°C Freely soluble in triethyleneglycole (@ 80°C) and n-butanol 4,4'-methylenebis-(2,6-diisopropyl)-aniline. Lonzacure M-DIPA is an excellent chain extender for elastomeric polyurethanes (PU) especially useful in systems cured at room temperature. It is also a curing agent for epoxides (EP) and an intermediate for organic syntheses. PU formulations based on Lonzacure M-DIPA are suitable for cast elastomers, RIM elastomers and coatings for construction industry. In EP it is suitable for tooling, prepregs, chemical resistant coatings, laminates and filament winding. processing at room temperature, good dynamics, good hydrolytic stability, low water absorption high % elongation at high modulus, high Tg (> 170°C), long shelflife of prepregs Benzenamine. Used as a chain extender for elastomeric polyurethanes and as a curing agent for epoxides in chemical resistant coatings for construction industry. Provides good dynamics, good hydrolytic stability and low water absorption in polyurethanes. Offers high elongation level at high modulus and high Tg (>170°C) in epoxides.
