Description

Short description
G/Flex 650 is a liquid cured epoxy adhesive formulated for permanent waterproof bonding of fiberglass, ceramics, metals, plastics and damp or hard-to-bond woods. It offers improved flexibility compared with standard epoxies while providing structural adhesion for demanding repairs and assemblies.

Key benefits
  • Excellent adhesion to tropical and domestic woods that are difficult to bond
  • Adheres to dissimilar materials: fiberglass, ceramics, metals and plastics
  • Creates structural bonds that absorb expansion stresses, impacts and vibrations
  • More flexible than standard epoxies and polyesters yet stiffer than adhesive sealants
  • Easy 1:1 mix ratio, suitable for technicians and workshops
  • Can be modified with fillers and WEST SYSTEM additives for specific applications; suitable for wet-taping and fiberglass cloth

Usage & handling
  • Mix ratio: 1:1 (by volume)
  • Working time: ~45 minutes at room temperature
  • Pot life: ~75 minutes at room temperature
  • Initial cure: 3–4 hours; can be sanded or worked after 7–10 hours depending on conditions
  • Compatible with WEST SYSTEM fillers and additives to adjust viscosity and mechanical properties
