APOLLO A3727 SPRAYABLE CONTACT ADHESIVE
APOLLO CONTACT ADHESIVE
Apollo A3727 is a sprayable, high heat resistance contact adhesive exhibiting fast solvent flash off and a long open tack time.
It demonstrates excellent adhesion to a wide range of substrates such as wood, decorative laminates, polyurethane foam, elastomers, plastics and metals.
In particular, the excellent hot bond strength of Apollo A3727 makes it suitable for the postforming of decorative laminates onto chipboard and MDF cores, using a wide range of static and continuous post-forming equipment e.g. Evans Rotork, Brandt Static, Bonding Systems.
APPLICATION:
Surfaces to be bonded should be clean, dry and free from loose particles dust and grease. Apollo A3727may be sprayed hot or cold. Hot spraying gives better atomization, better coverage and fast solvent evaporation. In conditions of high humidity, hot spraying will prevent a 'bloom' forming on the adhesive surface which would lead to poor bonds being made. Apply an even coat of adhesive to both surfaces to be bonded.
Allow a minimum of 2 minutes before mating surfaces.
Ensure intimate contact and coalescene of the adhesive films by passing the laminate through nip rollers or by platen pressing, using as much pressure and possible without crushing the components. Sustained pressure is not necessary. The high initial strength of the adhesive panels to be handled immediately.
