Aerodux 500 - Sequoia Aircraft Corporation F.8L Falco Construction Manual

The following information is a reprint of Ciba-Geigy Instruction Sheet No. GW.10k of May 1981.
Resorcinol-Phenol-Formaldehyde Adhesive. Aerodux 500 is supplied in three grades: 500.F
(Fast), 500.M (Medium) and 500.S (Slow). Hardener 501 is used with each grade.
Aerodux 500 liquid resins mixed with Hardener 501, a resinous liquid containing filler, provide a
range of resorcinol-phenol-formaldehyde adhesives which are fully weatherproof and gap-filling,
and are expecially suited to the manufacture of large laminated timber structures. Aerodux 500
adhesives are also suitable for use in the production of heat-resistant composite structures, e.g.,
fire-check doors. They are resistant to acids, weak alkalis, solvents and boiling water.
Aerodux 500 adhesives are simple to prepare. Both resin and hardener are liquids, and are mixed
in a 1:1 ratio.
Aerodux 500 resins with Hardener 501 meet the requirements of BS 1204: Parts 1 and 2 (Type
WBP), BS 1203 (Type WBP) and DIN 68 705 (AW 100) and can be released in accordance with
DCI and ARB regulations.
The three adhesives are highly suitable for bonding a wide range of materials to porous substrates.
These materials include:
Wood, improved or densified woods, e.g., 'Hydulignum'.
Asbestos-based boards, brick, concrete, unglazed porcelains.
Rigid expanded plastics, e.g., expanded ebonite, polystyrene, polyurethane and PVC.
Industrial and decorative laminated plastics (phenolic resin-based or phenolic resin-
backed).
Leather, cork, linoleum, nylon.
