Applications
Crystic® VE 671 PA T LF is recommended for:
Chemical storage tanks & vessels
Corrosion barrier and structural laminate systemsGRP swimming pools
Certified corrosion-resistant tie layers (AS1838 compliant)Industrial corrosion protection
Linings and laminates exposed to aggressive chemicalsHand lay-up & spray lamination processes
Vertical or complex mouldings
Where sag resistance and laminate quality are critical
ATL Technical Support
ATL Composites provides technical guidance on corrosion barrier design, resin selection, catalyst optimisation, and laminate sequencing to ensure Crystic® VE 671 PA T LF systems deliver long-term chemical and thermal performance.
Processing & Handling
Crystic® VE 671 PA T LF is pre-accelerated and designed for cold curing. It requires only the addition of a medium-reactivity MEKP catalyst, such as Butanox® M50 or Butanox® LPT, typically at 1–2%.
Important: Catalyst and accelerator must never be mixed directly together.
Post curing is recommended to achieve optimum chemical, water, and heat resistance before placing parts into service.
