Description
4,4'-Methylenebis(2-methylcyclohexylamine), commercially known as Laromin C or Laromin C 260, is a cycloaliphatic diamine with CAS number 6864-37-5 and EC number 229-962-1. It carries no assigned E-code and is classified under HS code 29213000 within the amines category.
In epoxy formulation, this diamine functions as a stoichiometric curing agent, reacting with epoxide groups to build a crosslinked thermoset network with elevated heat and chemical resistance. It is applied in structural adhesives for automotive and aerospace assemblies, and in high-performance protective coatings where a low-yellowing, aliphatic cure profile is required.
This material is supplied as a clear liquid and is available in standard industrial drum and IBC packaging formats. It falls under REACH registration requirements for supply within the European Economic Area. Procurement teams should confirm current SDS documentation and lot-specific purity data directly with the supplier prior to ordering.
