FiST 7064 is a two-component, ambient-temperature-cured structural foam with adhesive properties that bonds a variety of substrates and fills variable gaps.

It provides high strength at low density, fast reaction times and excellent adhesion, and is free of isocyanates and organic volatiles.

How to use

• Check each cartridge opening is free of obstruction before use
• Apply through a 10 mm x 24-element helical static mixer and purge until uniformly mixed
• Bulk: use meter-mix equipment with 316 stainless-steel contact parts and PTFE-lined hoses
• Remove excess before curing with a general-purpose organic solvent; avoid disturbing the bond during clean-up
• Paint surfaces exposed to UV (sunlight)

Typical applications

• Bonding and gap-filling between irregular surfaces
• Reinforcing substrates and retaining fasteners, inserts and brackets
• Sealing against dust and water
