Lonzacure M-MIPA 4,4'-methylenebis-(2-isopropyl-6-methyl)-aniline 16298-38-7 Lonza Crosslinking / Coupling / Curing Agents >> Amines /Amides >> aromatic Epoxy (EP) PU - Prepolymers 4,4'-methylenebis-(2-isopropyl-6-methyl)-aniline M-bis Anilines are a novel class of toxicologically friendly and easy to handle polyurethane chain extenders for advanced two component polyurethane cast and spray applications where extremely high thermomechanical, chemical and abrasion resistance are needed. As epoxy hardeners they provide improved use temperatures, moisture absorption and impact resistance. Areas of use are coatings, aerospace, automotive and the general industry. Lonzacure M-MIPA is used as a chain extender for elastomeric polyurethanes (PU), curing agent for epoxides (EP), precursor for polyimides, polyesterimides and polyetherimides as well as an intermediate for organic syntheses. PU formulations based on Lonzacure M-MIPA are suitable for cast elastomers, RIM elastomers and coatings for construction industry. EP formulations based on Lonzacure M-MIPA are suitable for prepregs, laminates and filament winding especially in aerospace applications. good dynamics, good hydrolytic stability, low water absorption low water pickup, high Tg (> 170°C), high impact resistance Benzenamine.
