Aldirez BH is our aldimine latent curing agent. It hydrolyses on exposure to moisture, producing a reactive amine crosslinker and benzaldehyde.
Our Aldimines are particularly useful in high-build polyurethane systems, as it promotes faster through-cure and doesn’t produce any carbon dioxide. It also speeds up the cure of low NCO containing prepolymers.
With good in-can stability with aromatic prepolymers, Aldirez BH is ideal for flexible joint sealants, elastic bonding adhesives and general sealing and bonding compounds.
