Genetic guidelines

Avoid air pressure settings above 7 bars as this can 
damage the spray gun

Only use VACTAC200 hot melt adhesive with the 
spray gun. New adhesives will need to be qualified by 
R&D before use

NEVER

leave the gun lying on its side while turned 

on. This will cause adhesive to run back into the 
chamber and jamming the gun.

Prevent contamination of the adhesive slugs. 
Particles in or on the adhesive slugs can block the 
nozzle of the spray gun.

Always follow current guidelines for adhesive dosage. 
Over dosage can cause delamination's.

Always consult AXVAC before potential changes of 
nozzle type. 

Hot melt adhesive should not be used for full surface 
joining.

For large glass pieces it is recommended to join fix-
points in the glass and adhere the fabrics from these 
inside the mould as opposed to applying adhesive to 
the entire ply outside the mould.
