Aldirez A

Aldirez A is a bis-aldimine and works as an accelerator for moisture cure PU primers that hydrolyze on exposure to moisture, yielding a reactive amine crosslinker and an aldehyde.
Aldirez A is specially designed to accelerate cure in moisture cure PU systems and is suitable for use with both aromatic and aliphatic prepolymers. Aldirez A inhibits CO2 generation and it allows the formulator to accelerate the cure of PU primers with a workable application potlife.
Features
· Prevents the production of CO2 gassing which would result in bubbling and film defects and works as cure accelerator for 2K PU primers
· Enables bubble free curing at elevated temperature & humidity levels
· Suitable for use in aromatic and aliphatic prepolymers
· Very low viscosity
· Provides excellent low temperature cure
Typical Applications
· 2K PU primers for concrete and metal
