Method of use

Adhesion and surfaces preparation:

Nature Clean, dry, free of dust and grease.
Priming When bonding, Formoa® Surface Activator may be used on non-porous surfaces. We recommend preliminary compatibility tests previous to application.

Application of the adhesive:

Formoa 066 can be applied by a manual or pneumatic gun onto only one part. Join the parts together within 40 minutes. When compressed, the bond line thickness should not be less than 1-2mm, in order to allow the correct curing and best performance characteristics once cured.
Onto large surfaces the adhesive can be applied in parallel lines, 20-40cm apart.
