Aldirez BH is an aldimine latent curing agent that hydrolyses on exposure to moisture, yielding a reactive amine crosslinker. Aldirez BH is specially designed for one component PU systems and is suitable for use with both aromatic and aliphatic prepolymers where it is used to prevent gassing in sealant and adhesive applications.
- Prevents the production of CO2 gassing which would result in bubbling and defects
- Enables bubble free curing at elevated temperature & humidity levels
- Suitable for use in aromatic and aliphatic prepolymers
- Very low viscosity
- Low temperature crystallisation stability (down to -20˚C)
