TCD Diamine

TCD Diamine (CAS 68889-71-4), also known as 4,7-methano-1H-indenedimethanamine octahydro, is a cycloaliphatic diamine used as a curing agent and crosslinker in high-performance polymer systems.

Where is TCD Diamine used?

• Epoxy coatings: cures systems requiring low yellowing, UV stability and hard surface films
• Industrial floor coatings and protective topcoats
• Structural adhesives and sealants: crosslink density supports high bond strength in assembly and construction
• Building and construction: grout systems, anchoring compounds and concrete repair formulations requiring chemical resistance and mechanical strength
• Casting resins and composite matrices require a stiff, thermally stable network.

Good to know: Buyers should confirm amine value and purity specifications with suppliers to ensure compatibility with target epoxy equivalent weight ratios and formulation stability.

Commercial specifications

• Drum and IBC quantities
