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.

Its rigid tricyclic backbone delivers elevated glass transition temperatures and chemical resistance in cured networks, directly influencing formulation performance and end-product durability.

In epoxy coatings, this diamine cures systems that require low yellowing, good UV stability, and hard surface films. This makes it a preferred choice for industrial floor coatings and protective topcoats.

Structural adhesives and sealants benefit from the crosslink density it provides, supporting high bond strength in demanding assembly and construction applications across various industrial sectors.

In the building and construction sector, it is used in grout systems, anchoring compounds, and concrete repair formulations where chemical resistance and mechanical strength are critical for success.

Polymer formulators also incorporate it into casting resins and composite matrices where a stiff, thermally stable network is required to meet specific engineering and performance requirements.

The product is supplied as a liquid and is available in technical grade, with supply typically offered in drum and IBC quantities suited to industrial formulation volumes for large scale use.

Buyers should confirm amine value and purity specifications with suppliers to ensure compatibility with target epoxy equivalent weight ratios and overall formulation stability during production.
