Product Name:N,N'-di-sec-butyl-4,4'-methylenedianiline
English Name:N,N'-di-sec-butyl-4,4'-methylenedianiline
CAS No.:5285-60-9
Aliases:MBDA, MDBA, 4,4'-bis(sec-butylamino)diphenylmethane, 4,4'-di-sec-butyldiaminodiphenylmethane, 4,4'-methylenebis[N-(1-methylpropyl)benzenamine], Dinlink 4200, TIAH LINK 4200
Molecular Formula:C21H30N2
Physical Properties:Light yellow to amber transparent liquid; density approx. 1.0 g/cm³ (25°C); boiling point approx. 430°C (atmospheric pressure); flash point approx. 207°C; very low vapor pressure. Possesses secondary aromatic amine structure with low viscosity at room temperature, good compatibility with isocyanates, soluble in common organic solvents such as alcohols, ketones and aromatic hydrocarbons, and moderate reactivity.
Uses:Used as a polyurethane chain extender/curing agent in flexible foams, rigid foams, coatings, adhesives, sealants, elastomers and polyurea systems, typically at 1-5% of the polyol weight. In flexible foams it improves tensile strength, tear strength and load-bearing capacity; in rigid foams it increases compressive strength and dimensional stability while reducing brittleness. In MDI/TDI systems it enhances adhesion and surface quality; it is also suitable for spray polyurea and metal/concrete repair compounds, slowing gel reaction and improving substrate wetting and adhesion.
Technical Specifications:
Purity: ≥99%
Appearance: light yellow to amber transparent liquid
Molecular weight: 310.48
Amine value: approx. 361 mg KOH/g
Moisture: ≤0.1%
