Method of use

Adhesion and surfaces preparation:

Nature Clean, dry, free of dust and grease.
Preparation Clean with Formoa® Surface Activator
(bodyside and glass).
Priming Where no ceramic frit protector layer exists, use Formoa® Primer PG. We recommend preliminary compatibility tests previous to application.

Application of the adhesive:

Formoa Screen Extra 2 can be applied by a manual or pneumatic gun onto only one part. Join the parts together within 10 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.
